Case paperwork completed 9/11/2020, site inspection conducted on 11/11/2020.
Peroxide treatment conducted last week all pens were treated, freshwater treatment planned soon.
Cleaner fish to be input soon.
Poor weather conditions made stock inspections difficult however no issues noted and the fish sampled for VMD seemed in good condition.
Holes were observed on three pens two of which were not large enough for stock to have escaped through however one of the holes was ~30cm, in diameter and was below the water line further along the same pen another hole of similar size had been repaired with cable ties. Site staff were to repair immediately. All holes were considered to be caused by seals. The location on the pen would reduce the likelihood that any fish had escaped. The manager was informed to report this to the FHI.
Freshwater treatments are planned for next week so pen count should be completed then.
On return to the lab a mortality event report of 37,281 (4.03%) was received by the Inspectorate for the site w/b 2/11/2020, the remote inspection was conducted on the 9/11/2020 but there was no record of this event having occurred, it was also not mentioned during the remote inspection or the site visit. Following discussion with the site contact regarding this omission, it was reported that the mortalities had occurred post peroxide treatment and were removed from the pens over the weekend and had not been input to the database.

Stock transferred onto site from Kingairloch (Loch Ness, Aquagen ova) in January and March 2024. Site was fallow for 6 months prior to transfer. Delayed input due to plankton in the area in October 2023, risk assessment completed for transfer between management areas. Salmon split into Marulaig Bay in May.
Lumpfish on site from Ocean Matters. Received first batch of locally wild caught ballan wrasse on 31 May (input into pen 7 with large grade as no lumpfish in this pen). Expect to input more wrasse to increase percentage stocked to ~2%.
Strategic treatment of fish with SLICE in April 2024. Freshwater treatment in May 2024 due to poor gill health.
Main cause of salmon mortalities is poor gill health and poor performers. Main mortality cause in lumpfish is Tenacibaculum
(three cages of lumpfish treated with florfenicol post delivery). Mortalities are removed daily using Foover and sent to
Whiteshore Cockles for disposal.
Two weekly mortality events above threshold not reported for previous cycle. In addition, the percentage for one weekly mortality event (wk 26 in 2023) was recorded incorrectly in the mortality event spreadsheet (reported correctly by company at the time). Corrected to 1.41%.
Fish feeding well, but had been on starve for 2 days due to presence of plankton. Approximately 1-3 floating dead fish seen in pens 1-6. Two moribunds removed from pen 1 plus two feeding fish from pen 1 for VMD, diagnostic samples taken from all fish. [Original PDF]

The site is split into two distinctive sections relating to development stage, a fry section containing 8 45m3 recirculation unit tanks and a separate parr section, consisting of 8 175m3 flow through unit tanks.
Fish in both sections were observed to be in good health, no clinical signs of disease were observed from the physical inspection of the site. Fish were observed shoaling well and responding positively to routine feeding regimes. Mortality has been low in recent months and the fish appear to be progressing well in their development stages.
A mortality event from 22nd - 28th August 2022 is still under internal review following a loss of 53.33% which affected all 8 tanks within the fry section of the site. It is believed that water supplied to the site had become contaminated prior to water intake which lead to a rise in hydrogen sulphide levels leading to significant mortality within the fry section. Following a deep clean of the sites water reserve and facilities, the site was restocked and no further issues have occurred.
The sites own thermometer was used to obtain a water temperature reading for biosecurity reasons. [Original PDF]

From mort report; "This mortality was in parr unit (separate from the fry unit detailed in wk18 mortalities). Issues with pH in water. Lag between pH buffer added and probe feedback. Changes have been made to probes and protocols for improved real time feedback to reduce lag and improve response. Mortalities in remaining stock being closely monitored and they may be culled. Discussed with and he will inform APHA".
Historic mortality event from 22nd - 28th August 2022 a loss of 53.33% which affected all 8 tanks within the fry section of the site. It is believed that water supplied to the site had become contaminated prior to water intake which lead to a rise in hydrogen sulphide levels leading to significant mortality within the fry section. Following a deep clean of the sites water reserve and facilities, the site was restocked and no further issues had occurred.
Currently in the fry section 8 tanks with 1309989 fish @ 0.7g which will be ready to move to the parr section in 6 weeks. Parr section was stocked on 10th-18th April 2023 from the fry section
Peak daily mortality in parr section; 8/5/23 34500 2.52%, 9/5 83768 6.26%, 10/5 134352 10.76%, 11/5, 140576 12.61%, 12/5

Records checked and adequately maintained; site details, mortality records and health surveillance records.
In the parr section the prob monitoring the PH is placed just after caustic soda or bicarbonate soda is added. This results is the readings from this probe jump up and down so the cut off from this probe has been over-ridden. There are 8 tanks in the cycle but only 4 were stocked at the time of the incident. 10 cycles prior to this one with no issues. 24/5/23 TMS used to cull remaining stock due to compromised (burnt) gills.
Health reports from 15/5/23 from Pharmaq; gills evidence of lamellar surface damage with adhesions, hyperplasia and lamellar fusion. Epithelial cell necrosis/apoptosis and detachment sometimes associated with debris containing filamentous bacteria and lower numbers of large segmented filamentour bacteria like organisms. Hyperplasit filament thickening and clubbing. All fish showed eosinophilic or hyaline globular inclusions within kidney and splenic macrophages. Post acute gill pathology may indicate recent irritant or toxic gill lamellar surface damage.
Poxvirus results from 12/5/23 - PCR 5/5 positive Ct values range 23.5-26.9
Cycle consists of; Tanks-probes- drum filter- biofilter - doser- probes- tanks - Also concrete mixing tank which had a thick biofilm above the water line but below the water lie was stripped clean. Thought combination of caustic soda and bicarbonative soda may have removed the biofilm into the system. [Original PDF]

Unhatched eggs not yet measured out as still given stragglers a few extra days. 10 comp hatch units with 8 trays each (80 trays total) 60 trays stocked. A few weeks fallow in between batches planned for cleaning and disinfection in January 2021.
Current batch of Ova arrived 20/11/2020. No treatments applied in the hatchery. Hatchery has it's own recirculation system, separate from the system for the fry unit. Single biosecure entry point to the unit. Plan to eventually have 4 inputs of ova to the unit every year to have fish ready each quarter, however implementation depends on the progression of building works and refurbishment of the other units (smolt).
Due to biosecurity concerns used sites own thermometer.

Site visit conducted accompanied by APHA Vet following reports of significant mortalities.
Initial mortality event report was wk 3 50,620 (3.56%), wk 4 30,488 (2.22%), wk 5 147,668 (11.01%).
During stocking of the site there was an issue with the pipework, a burr on a reducer resulted in some physical damage this was replaced and transfers continued without further issue. Mortalities continued to increase post transfer, some fungus was reported but following disease screening furunculosis was identified as the underlying cause of the elevated mortalities. In week 5, on veterinary advice, the fish were transferred to sea (Aird) to reduce the infection pressure within the system. The site was fallowed on the 6/2/2024, A full clean and disinfect was to be completed.
Due to the issues that have occurred onsite, the surveillance frequency could not be assessed appropriately as the frequency of movements on and off site were not representative of normal site operations, the site will remain medium risk. [Original PDF]

Mortality notification 2020: w/b 14/9/20 5g to smolting @ 2.73% fungus; w/b 21/9/20 5g to smolting @ 2.11% fungus & handling
Site currently short staffed and tanks were being checked during the inspection, so 1 or 2 morts observed in some of the tanks. One tank had 5-10 fish with visible fungus but these were all swimming actively. Overall water was peaty and no visible fungus observed in any of the other tanks (fungus is more visible in peaty water conditions). Some issues with fin nipping
(dorsal fins) recently on site, this was apparent across the site but more prominent is some tanks than others. This is due to fish taking some time to fully come back onto feed post vaccination and feeding not having been optimal recently as well as this strain of fish being thought to be more aggressive, but feeding rate has been adjusted and this is expected to resolve issues with fin nipping.

The mortality levels before the 21/12/2021 included the mortalities from the flow through unit at Russel Burn. For reference,
Russel Burn comprises of two units; a flow through unit and a recirulating smolt unit. The flow through unit was demolished on the 11/01/2022. Therefore, Russel Burn now only houses 7 tanks, which is also known as Applecross Smolt unit.
Nevertheless, the reported mortalities almost totally comprise of morts from the smolt unit.
Recent mortality w/b 03/01/2022 (week 1 2022)- 4.79% as a result of Fungus
Fish that were transferred on 27/12/2021 and 28/12/2021 to Aird reported a 2.19% post transfer mortality. Further smolts have been transferred as of 12/01/2022 to the SW site Aird. The majority of mortalities observed were in the smolt unit, with almost all affected stocks now fully transferred to SW sites. Pre-transfer checks were conducted.
Smolts went out yesterday- Aird sw sites. Majority of mortalities have been in the smolts which have now been transferred.
Pre transfer health checks are conducted. The remaining stock on site are being transferred to SW sites in week 5. There is one tank of Native Hebridean stocks at 54g average weight remaining and is planning to be transferred in week 14 2022.
These fish will be transferred to Sgeir Dughall and Greanamul. The remaining stock with lower levels of fungus are being monitored and treatment are available if required e.g. Aquacen as well as raising salinity levels to 4.0 with the addition of salt.
Vaccination occurs in the parr unit prior to smolt unit transfer.
Mortalities are disposed of in bins which are uplifted by Billy Bowie and taken to Dalry. This is a common process with
Applecross site.
In regards to transfers, the site is fitted with a pipe from the smolt unit 1km from the wellboat docking site.

Remote paperwork by 01/02/22. Site inspection carried out by 02/02/2022.
Fish that were transferred on 27/12/2021 and 28/12/2021 to Aird reported a 2.19% post transfer mortality. Further smolts have been transferred as of 12/01/2022 to the SW site Aird.
On 19/01/22, the fish in Stofinfisker stocked tanks 1,2 4 and 6 were noticed to be behaving strangely (loss of equilibrium and coming to the surface). At time of incident water parameters were checked and normal for ammonia, nitrite, CO2, pH, O2, alkalinity and salinity. Monitoring of the stock was increased with staff being on site throughout the whole night. Water samples were taken when the change of behaviour was first noticed and further samples taken during the event. These have been sent away for heavy metals.
20/01/22 - Mortality levels in the 4 affected tanks had increased to 90% and decision was made to euthanise the remaining fish with T.M.S. Fish were sampled for histology showed gill irritation and secondary liver and spleen pathology. Considered to be a toxic irritant to the gills - water quality or water bourne insult considered the cause. No conclusions but hydrogen sulphide thought to be the cause. The effected tanks have been cleaned and the pipes pumped through, Looking for a dead spot in the pipe work or bio filter. This is the 2nd cycle of fish through the site.
Mort removal occurring over two days and are disposed of in bins which are uplifted by Billy Bowie and taken to Dundas
Chemicals Dumfries. This is a common process with Applecross site. With the resent increase mortalities, morts have also been collected by Fergusons Transport for disposal at Dundas
Fish in tank 7, Native Hebridean origin, showed similar signs at the time of the event but the mortality levels were far lower.
This stock was not euthanised and have since recovered. No lethargic or moribund fish were identified during the site inspection. Mortality levels have greatly reduced post event and were only at 57 (0.018%) fish out of 321,696 at the time of inspection on week 5, 2022 (wb 31/01/2022).
Aquacen was only administered to the stock that perished/were euthanised. Fish remaining on site were not in withdrawal from

Timeline of mortality events:
A review of the biosecurity on site was undertaken prior to the transfer of fish into the smolt unit, where the farm was zoned off and additional biosluices were put in place to minimize horizontal contamination.
Fish were vaccinated into the smolt unit which ended on 11/05/2024. Pre-transfers tests showed that positive results for furunculosis were reported on 14/05/2024 in S04 (VHWP inspected on 20/06/2024 which showed timeline of testing and mitigation measures noted). Feeding rates had reduced following vaccination (15/05/2024) and it was suspected that treatment may be required. Mortality began to significantly increase on 16/05/2024. Aquatet (oxytetracycline) was administered on 15/05/2024 to 24/05/2024. As a result, mortality and moribund removal was increased to 24hr shift. Extra staff has also been brought in to support the mortality and moribund removal. A second rise in mortalities was noted on 01/06/2024, with a second round of Aquatet administered on 04/06/2024. Due to stock shortages Florocol was only admistered on 12/06/2024 (10 day treatment; end on 21/06/2024).
Health team inspected the fish on 04/06/2024 and subsequently on 10/06/2024, where latterly many moribunds were observed, with a significant majority population seen to be healthy and feeding well. Third party health report from the
11/06/2024 (bacteriology) confirmed sensitivity results, which highlighted that aquatet was partially effective but fully sensitive to Florocol.
Currently, there is an 8 week window between next crop in the smolt unit; plans are to clean and disinfect for two weeks and the reboot the biofilter for 6 weeks.
Business is currently reviewing procedures and planning future mitigation. Additional immunity is being considered for future populations but require further research and work with additional vaccines. There is also a focus on biosecurity, where procedures involve a cleaning protocol between populations, swab for pathogens and if there is evidence of specific pathogen, killing of the biofilter will occur. The biofilter will be cleaned with caustic soda, which will be added in circulation, followed by
AquaDes (periacetic acid). To ensure removal of gross bioflims, pressure washing will be conducted. Also, business used an
ATP swabs, which will confirm if any living material still present in the biofilter.
Peak mortality noted for the 1st cluster of experience mortality on 19/05/2024 with ~4.50%, specifically in tank 1 and 5. The second cluster of mortality had a peak rate of ~3.50%, where tank 2 and 6 saw the majority of the mortality.
Treatment Withdrawal: Aquatet ( remaining 774 degree days as of 20/07/2024); Florocol (150degree days; prescription seen);
SLICE (treatment began 17/06/2024; withdrawal period 200 degree days)
Site thermometer used due to biosecurity, thermometers are regularly checked against a mercury thermometer.
Site and paperwork inspection conducted 20/06/2024. During site inspection, fish in smolt unit observed to be swimming well and actively feeding. Very few moribund or lethargic fish observed in the tanks. Mortalities that were observed were found to have haemorrhaging on bellies and some exophthalmia. Some fish were observed to be swimming well but had evidence of large healed lesions. 5 fish lethargic and moribund fish were removed for diagnostic sampling. [Original PDF]

Applecross 3 new sites
Applecross Smolt Unit 2- almost complete and looking to stock 2-3 weeks time from Applecross Smolt unit. Was able to inspect all the site.
Applecross ongrowing 1- will be complete in August 2023 and was able to inspect some of the site
Applecross ongrowing 2 - will not be complete until October 2024 - not able to inspect any of the site.
One transfere line for all three sites - underground with no water return. Line out from each site joining I output pipe.
Smolt Unit 2 and Ongrowing 1 share a grading area separate from the sites. Ongrowing 2 will have its own grading area.
Sites will have site specific staff generally. Smolt unit 2 and ongrowing one are entered from a communal service corridor which has shared office and canteen space. Entry into the sites is via two separate rooms where PPE and disinfection will be carried out prior to entry. The rooms were available for inspection but sinks benches and storage for the PPE was yet to be added. Smolt Unit 2 and Ongrowing 1 have a one way fire door out of the site into the service corridor but these doors will only be used for emergency exit. Both sites will share a common food silo from where food will be piped into the sites. Ongoing 2 will have a separate food silo.
Each site will have a mort disposal cone which Morts will be tipped into and pumped to a mort disposal tank off site from where morts will be pumped into tankers for disposal. Destination not determined yet.
The plan is to grow the fish on site to 450g with an estimate of 10 million fish capacity once all three sites are running.
Vaccination will be carried out prior to input at Hatcher 2 and ongrowing 1 and 2.
All three sites will be full recirculation Smolt 2; 4 tanks 1185m cubed, Ongrowing 1; 2300m cubed, Ongrowing 2; 2300m cubed.
• Info on site separation, connectivity and movement of staff and fish between different areas/sites. Is access only from separate external doors to each site? Or are there internal doors/passages for moving between sites? Are there any fire escape routes which compromise site separation and biosecurity?
Fish will be moved on from the Applecross Hatchery for ongowing at Applecross smolt unit and Ongrowing 1 and 2.
Ongrowing 2 is not build and is due for completion in October 2024. I therefore recommend that authorisation for this site is considered at a later date when the site can be assessed. From conversations it seems that the site will be totally separate from smolt unit 2 and Ongrowing 1 although attached.
Smolt unit 2 and Ongrowing 1 are physically septate with floor to ceiling walls. They will share a service corridor which will include shared canteen and office facilities however to access each of the sites you will need to pass through one of two
PPE/disinfection rooms on either side of the service corridor. One for each site. In addition each site will have a emergency exit which will operate one way from the site into the service corridor. I was informed this would not routinely be used and only used in emergencies.
At the time of inspection the PPE/disinfection rooms were empty but I was informed disinfection points, PPE storage facilities and sinks would be put in place prior to stocking. The emergency exits were operating as a two way door but I was informed this will also be changed to a one way door with the standard fire door bar on one side. My inspection of Ongrowing 1 was limited as it is still a building site – due for completion in August 2023. I was able to view the shared service corridor and two of the tanks. I was not able to access the water treatment area for Ongrowing 1. I was informed staff would generally be assigned to work at only one site.
There is also a second area that serves the two sites. A communal grading area which is accessed externally and can supply fish to either Smolt unit 2 or ongrowing 1.
Provided the sites are operated as described I saw no risk of cross contamination between the two sites. [Original PDF]

Toxic ammonia issue in 26/07/23 - 01/08/23 caused by a blocked waste discharge pipe. Approx. 213,000 fish (31%) lost in total. Facility had been open for 2 months before issue and this was the first batch of fish on site. The blockage was caused by a foreign object being dropped. The pipe now has a grate over it to stop anything similar happening in the future. The pipe was unblocked asap and fish transferred to sea.
Prior to toxicity issue, mortality was increased due to salinity supply issue on site. This increased Saprolegnia and approx.
21,000 fish lost (2.3%). The salinity supply issue has since been rectified. The fish were sent to Tarbert South. Veterinary approval received to transfer the fish to sea.
Ongrowing 1 to be stocked in December 2023. Ongrowing 2 to be stocked in Q3 2024 (approx.)
Salinity can be increased post vaccination if health issues arise. Background salinity kept at 2ppt and raised to 5ppt to treat minor issues such as fungus post treatment.
Fish smoltification slowed artificially by controlling light exposure and temperature. Temp is kept at a constant 12 degrees C.
Before transfer to sea, light exposure to be increased. [Original PDF]

On the date of inspection mortality was 1,800 fish for the site, with the highest numbers of mortality occurring in the middle of the pen group. Moribund fish were near the surface and particularly in pen corners. A number of fish were also observed gasping on the surface or working their opercula. Pens were being aerated. Lions Mane jelly fish observed on site and some fish were seen to have signs of interaction with jellyfish tentacles. Upon inspection of the gills of the fish removed, evidence of mild gill damage was observed, attributed to PGD by site staff. Site began H2O2 treatment on the day of inspection based on veterinary advice. The company currently operates both Ardessie A and B as one site. Veterinary reports are for the two sites referenced as one. Site advised that when conducting veterinary site visits to distinguish between the two sites. A bung was observed missing on one of the mort bins stored at the shore base, site staff reminded to ensure all bungs remain in place for biosecurity. A seal was observed near the site but predator mitigation was in place. Observed cleanerfish mortality is low.

Increased mortalities reported weekly since w/b 6/12/21 due to SRS and complex gill disease.
Yesterday trial peroxide treatment of 2 pens, this has caused increased mortality in the treated pens so have put off treating the remaining pens for now.
Vet report says mortality is driven by gill issues (complex gill disease) not bacterial infection. PGD, AGD, anaemia, environmental gill insult.
Looking at different treatment options like freshwater. However gills are damaged and any handling is likely to increase mortalities. Discussion on-going as to how to manage the situation.
Some sort of environmental damage possibly jellyfish or plankton bloom at some point. Gills damaged PGD in
September/October, then issues with AGD which were thought to be improving until situation started to deteriorate again in
December with complex gill disease causing large level of mortality (all reported). Water temperature still fairly high for the time of year around 9C.

Mortalities removed by dead sock and ensiled at Ardmair shorebase before disposal by biogas or incineration. Ardmair is currently divided into two pen groups, A and B. At the time of inspection the site was experiencing approximately 600 mortalities per day. Pharmaq Analytiq diagnosed complex gill disease in week 35 with AGD present. Upon inspection fish behaviour was lethargic with numbers of moribund fish observed near the surface and around the corners of pens. Recent mortality has occurred at both pen groups, with group B more affected. Mortality per pen on group B on the day of inspection was approximately 70 per pen with population N23 (currently in pen 5) the worst effected. The smaller grade fish were significantly more affected than the large grade. The fish on pen group A were displaying similar clinical signs of disease, although was not as wide spread. H2O2 treatments 23 & 24, 30 & 31 August and 01 September. Samples taken for diagnostics were pooled, two fish from population S6 (currently in pen 6 on pen group A) and 3 fish from population N23

Fish came on from Clachbreac and Loch Gairloch.
Fish were FW treated during transfer and also received FW treatments in August, September and the most recent one on
24/11/2021. Paramove was used in August 21 but lice numbers have remained <2 throughout the cycle.
Wrasse mortality since input is 1,500 (~1%).
Fish appeared in good body condition with the exception of some individuals displaying seal damage. Two wrasse mortalities and one salmon mortality observed across the site.
Fish carcass was discovered on site, outwith the net of cage 5. Suspected seal predation. Dive reports inspected from the previous day (7/12) and noted that a hole was discovered in the net of cage 7 measuring 8 mesh across. The hole was stitched immediately and an initial escape notification was received by the business on 08/12 - no fish are expected to have escaped. The nets on site are HDPE and are tensioned. Top nets are also deployed on all the cages. Site no longer uses
ADDs and no longer has a MML. Business is considering moving to predator nets beginning of next year. Divers were on site on the day of inspection, dive report was requested from the business - no further holes were discovered in any of the nets.
Site was inspected as satisfactory with regards to containment on the day of inspection.
Fish sampled for VMD appeared healthy and displayed a good feed response. [Original PDF]

Site had experienced a drop in feed, health screening identified piscirickettsia, this was treated with Aquatet and mortalities attributed to this have dropped.
Feeding response has reportedly increased over the last few weeks and the stock displayed a good feeding response at time of inspection. 4 fish removed for VMD appeared healthy. 3 dead observed across site, not fresh dead therefore not sampled, these were removed by site manager during inspection.
Visibility was good at time of inspection, 5 dead observed across site, not fresh dead, therefore not sampled. 7 lethargic fish observed across site deeper in the water. With the exception of the 7 lethargic and 5 dead, the fish were shoaling well.
Site is stocked with wrasse and lumpfish, numbers have been increased on last cycle and now aiming for 7% stocking of cleaner fish. Cleaner fish are now fed from the barge through the same feeding system as salmon, may also reintroduce the feeding stations around the outside of cage if required.
Site has replaced the hamster wheel top net supports with poles around the cage. Site manager prefers these as it removes equipment from the water that the fish could damage themselves on.
Site hoping upgrade cages from 12 x 120m circles to 8 x 160m circles
Site utilises ROV mortality removal system, which reportedly works well, also capacity to use uplift system if required.
Following confirmation of piscirickettsia, the site has been operating separately from the other Mowi sites in area and not sharing staff or equipment. [Original PDF]

Fish were transferred onto site from Loch Lochy and Glenfinnan in April 2020. Stocking density has been significantly reduced this cycle.
Thermolicer treatment was completed last Wednesday (12th) and average sea lice numbers have dropped to below 0.15 for all stages.
Ensiled waste is collected by Billy Bowie and taken to Energen, Cumbernauld.
Site manager reported good health and has observed a high feed conversion rate within the stock on site.
Site has done both live and dead haul harvests this cycle.
Fish were sitting deep in the water and only 3 lethargic fish were observed across the site. On the fish that were observed, some physical damage was noted but fish were active and demonstrated a strong escape response.
Lumpfish mortality across the site for April was 4.4%. Lumpfish observed on site appeared to be in good health.
Very few wrasse observed across the site. Mortality for the month of April was 1.2%.
Fish sampled for VMD appeared healthy.

21/10 - gill treatment started and mortality started to flare up.
Stoffinfisker and Aquagen on site, both have experienced similar levels of mortality. Recent mortalities on site have been attributed to complex gill issues, Rickettsia and Moritella. Mortality is constant across the whole site, however pens 6, 9, and 3 appear to be worst affected.
Cleaner fish mortality - LUM - 182,756 - 100% main cause has been flavovirus - 86,614 mortalities recorded. <100,000 not recorded.
Wrasse mortality - 31,484 Since input across the site. Background mortality.
Additional information on lumpfish mortalities -
During the inspection it was found that the site had suffered 100% mortalities of their lumpfish since input. Of these 86,614 were recorded with cause and around 100,000 had not been recorded. This has been referred to the Animal and Plant Health
Agency, as they have responsibilty for welfare. As ~100,000 mortalities of lumpfish were not recorded, these were not reported to the FHI, or the company vet.
Only 3 cages inspected on site due to timing constraints.

Any unviable eggs and hatch fails are removed via discharge pipe and end up in the collective Barcaldine ensiler.
Counts for unviable eggs occur at 65% development.
Movements of green eggs from Aquagen:
Occurred on 18/12/2023, 04/01/2024 and 11/01/2024. Trial batches: 12/12/2024 and 15/02/2024
Currently, next input into green egg unit not confirmed yet. Once fallow, site will be cleaner and disinfected and shutdown until a new date is set for an input.
Formaldehyde used on site to prevent/treat fungus (prophylactically). One treatments have been conducted: 16/02 (250ppm for 25mins). Flushed until all traces of formaldehyde removed (tested). Current plans to treat once per week.
Trial batches are also currently in the facility and unviable eggs have been removed. Viables ova will be culled prior to them hatching and will be disposed in ensiler. First trial: ~66000 unfertilised, unviable or mortality after shocking. Second batch

Fish on site will not be harvested. The site is used for smolt production before fish get moved off around 2.5kgs to neighbouring sites for final ongrowing and harvest.
Fish have been performing well so far with no significant health challenges. No medicinal treatments on this crop (with the exception of tricaine used for weekly sea lice counts); only FW baths combined with a flush have been completed on site and is reportedly resulting in 80-95% clearance.
Companies biologist will be visiting the site in wk32 to perform gill and lice checks along with water sampling.

Site was visited earlier in the year, but due to high water temperature, EC inspection had to be rescheduled.
Wellboat is expected on site this week after the inspection for a FW treatment.
Fish came on from Loch Shin, Garasdale and Yetts O' Muckart. Fish have been feeding and growing well. AGD has been diagnosed on site and is the main cause for mortality. HSMI has also been detected on site but is not causing signfiicant mortalities. Mixed stock from Stofinfisker and Aquagen. Stofinfisker stock have not been coping as well with the AGD and have made up the majority of the mortalities in recent weeks. Wk46 mortality event has been attributed to AGD combined with a period of bad weather and the site being unable to FW treat. FW treatment has been scheduled for the weekend following the inspection.
Site is being used as a nursery site and fish will be transferred to Skelwick and Moclett in the new year. Passive grading will be done in January and the largest fish will be moved first.
Fish were sitting deep in the water but those that were observed appeared in good physical health and were active in the cages. 2 moribunds and 2 mortalities were observed across the site. No other clinical signs were observed so were not sampled.

Site has poles for top nets rather than the central support, these were reported to work well at the site and cope better with large motion through the site. Also planning to fit these to the Mill Bay site.
Fish will be split to the Mill Bay site at beginning of 2022 after it has undergone fallow period. With fish at both sites being grown to harvest. All dead haul harvests at site. Bay of Holland has a smaller tonnage than Mill Bay, so may have been used as a nursery site, however, for this cycle some fish will be grown to harvest.
Mortality removal conducted using ROV, this was reported to work well.
Mortalities very low on site, no issues noted or observed. Fish removed for VMD appeared in very good condition with no sea lice.
A thermolicer treatment was conducted in early October, this reportedly gave a very good clearance
Site uses an Aquascale to measure weights of fish, this was reported to be very accurate and removes the need to handle fish for sample weighing, used especially on run up to harvests.
Currently 11 x 100m cages on site, grid has capacity for 16 x 100m cages.
No dead, moribund or lethargic fish observed during the inspection, CAS were training two new members of their health team whilst conducting gill scores. Mortality removal was also on-going during the inspection, using an ROV which goes between

On the day of proposed inspection, inspector informed that 4 seals were in observed in pen 12. Site was due to start harvesting pen 12 on day of site inspection, however due to seal observation, pen is required to be secure prior to the commecement of harvest. Divers were called immediately and inspection of the net was conducted 2.5 hours after seals were seen in pen. Efforts were made to coax seals out of the pen via the pens, however seals did not cooperate.
The stock on site are from Barcaldine Smolt Hatchery (Stofinfiskur).
The site visit was planned following recent weeks eleveated mortality, above the reporting threshold. The main cause of mortality on site was attributed to PGD, CMS and AGD. Most recent health report highlighted that post FW treatment (which concluded 22/12/2022) gills have improved.
All nets on site are Seal Pro nets, dating back to 2017. The mesh size of these nets is 36mm x 36mm squares. The net in pen
12 was last inspected in 16/06/2021, with strength tests highlighting overall satisfaction by Morenot.
Divers arrived on site and conducted a dive survey the net of pen 12. Five holes were identified with the biggest whole being 2 x 2 mesh squares. Divers on 25/01/2023 patched the net using cable ties and net rope. Dive checks usually occur monthly.
The nets after the production cycle are then sent back to Morenot for servicing and repair. Following the service, reports are generated to determine suitability of the net in the next production cycle.
At the start of the cycle, the site operates a double net system, with a smaller inner nylon net that is removed once maximum biomass density allowed by the RSPCA welfare standards is reached. There are plans in place for the nets provider to change to Knox nets for the next production cycle – continuing to be Seal Pro nets. In addition, the double net system will be reintroduced but with a larger and more robust inner net that will not need to be removed during the production cycle. In addition, the pen design will change to have higher poles as well as custom netting that is more durable.
From the size of holes observed from the dive report it was determine that no salmon would have been able to escape, not did a seal enter via this route. The theory is that the seals were able to get in the pen by hauling themselves over the hand rail and under the top nets which were pushed back to allow the site to start harvesting. The site staff, prepare the site for harvest to allow well boat access to the pen. To ensure that seal are not able to access the pen again, bungee cord has been used to tie the skirt of the top net tighter to the pen net. Divers were also present on site on the 26/01/2023 and 27/01/2023 to check the condition of the remaining pens on site which are scheduled for harvest, with the exception of two pens. Two remaining pens will be on site till March 2023 when site fallows. [Original PDF]

Fish came on from Barcaldine Smolt Unit and originated from Stofnfiskur.
Mortalities started increasing in wk33 and have remained above 1% across the site since. Samples taken by Pharmaq in
September 21 confirmed the presence of AGD, HSMI and SGPV.
Site has been destocking through harvesting. Worst affected cages have been targeted first. Harvest ongoing and site will likely be fallow by the end of the year.
Weekly lice counts have remained relatively low since input, although the site has been treated to prevent lice counts increasing. Site received thermolicer treatments in wk17, wk25, wk26 and wk28 and a hydrolicer treatment in wk30. Alphamax bath treatments were done in wk29 and wk32, but the site manager has reported that the addition of cleanerfish has significantly helped reduce and keep lice numbers low.
Combined cleanerfish mortality since input (July 21) is at 2%. Cleanerfish observed during site inspection appeared healthy - no cleanerfish moribunds or mortalities were observed across the site.
The majority of the fish on site appeared in good health and were active. 3 mortalities and 8 moribunds were observed across the site, 5 moribund fish were removed for diagnostic samples.
A boat was due to arrive on site later this evening to harvest a further cage. Site is doing live haul harvests to South Shian processing plant.

During site inspection, seagulls were observed landing on bird net and weighing it down. Site has highlighted that birds are an issue but all mitigation measures in place. In addition, an upside down fish was observed in pen 8, removed to inspect it and deemed that no clinical signs were observed and therefore no diagnostic sample taken.
1 fish was removed for VMD sampling and was observed to be in healthy condition. Fish on site were observed to be shoaling well and feeding well too.
In addition to the routine inspection, a statutory inspection was conducted due to confirmation of BKD at Chalmer's Hope
(FS0993) - within one tidal excursion of the inspected site. The inspection was conducted to rule out signs of clinical BKD. No fish were observed with signs of clinical BKD. [Original PDF]

Concussion main cause of physical damage, looking to install bird poles to mitigate further damage.
Site uses environets, these seem to work well on the circle pens. A couple of pens had some warping of the handrail, this was reported to be due to completing swim-throughs when the temperatures were high, the plastic becomes slightly more maleable and when the weight of the wet net is supported on the handrail some warping occured. A trial of dyneema environets is ongoing with one pen fitted, the net is significantly lighter reducing strain on the pen structure.
The water was very clear allowing a good inspection of the stocks. Wrasse and lumpfish all appeared in good health. The salmon appeared very jumpy however no issues with lice are reported and the fish sampled had zero lice burden. Due to the issues with concussion the 'hamster' wheels are being replaced with bird poles.

Inspection taking place following several mortality notifications since mid-July being over the reporting criteria. First mortality event reported for wk 28 at 1.01% (10.597 fish) and peaked at wk 33 at 5.24% (49,691 fish).
Recently mortality has reportedly been falling since wk 33. The mortality notification for wk 34 was down to 3.69% (33,209 fish).
Mortality has been attributed to multifactorial causes as PD, SAV, AGD, PGD, Pasturella skyensis and Rickettsia have all been identified on site. Caligus levels are reported to be rising at wk 30. Rickettsia being treated with florfenicol and is reported to be effective. A freshwater treatment has been carried out on 28/05 - 09/06 to deal with AGD and caligus. Another freshwater treatment was due to take place on the week of the inspection but has been postponed to reduce potential for physical damage following a successful antibiotic treatment
Pasteurella skyensis test positive from 07/08/2023. Fish vaccinated against this.
Antibiotics (florfenicol in-feed) used on site, finished on 22/08/2023 after a week long treatment.
Cage 2 mortality highest this summer (from Loch Ness). Loch Ness fish went to cages 2 and 6. Mortality in cage 6 is in line with other cages
Fish reportedly feeding well on week of inspection. Feeding has increased substantially since antibiotic treatment
At least one of the biologist team on site each week.
Fish from Loch Lochy and Loch Ness (both hatched in Loch Ailort)
Cages are 100m plastic circles
Background mortality is dealt with by ensiling. Due to increased mortality skips are being used currently. Two companies are used to dispose of increased mortality. One (J.A. MacDonald) takes mortality to Whiteshore Cockles and Dundas and the other (Billy Bowie) disposes of fish at Barkip and Dundas.
Peroxide treatment ended early on 11/08/23 as fish in cage 2 did not respond well to treatment and mortality increased. Water temperature at the time was about 15 degrees C.
Thermolicer treatment from 19/06 - 22/06 and 10/07 - 13/07 to deal with lice levels
Peroxide used on 17/7/23 and 11/07/23 both to treat for AGD
Alphamax treatment from 27/07 - 30/07 and 30/08/23 - 06/09/23 to treat rising Caligus levels
All lice treatments are reported to be successful.
Feed supply issues (caused by excessive heat where the feed was stored at the feed mill) meant that the fish ate less feed than planned for the 8 weeks before the inspection.

It has been accepted by industry that freshwater treatments will lead to elevated lumpfish mortalities. No alternative solution was given. Site manager said that it is difficult to dewater lumpfish as a result of size and shape. Staff try to remove fish as much as possible with hand nets. Increased handling may also contribute to mortalities.

Stock Origin: pen 5, Lochailort, Fanad; rest of the pens, Inchmore, Aquagen
Harvests deadhaul and livehaul- to Blar Mhor.
Statutory inspection conducted following report from the business that clinical signs of Bacterial Kidney Disease (BKD) have been observed on 23/05/2024. The detailed sampling of fish by the business commenced on site following the observation of clinical signs at Seaforth (FS1042) and subsequent CDN placement. The stock origin of fish currently at Caolas a deas is noted as Trilleachan Mor (FS1118). Fish previously transferred to Trilleachan Mor originated from Seaforth (same batch of fish).
During the site inspection, all stocked pens were inspected and 5-10 lethargic fish were observed in the majority of the pens.
The majority of these fish were found to be deformed. From the ten fish that were removed, 4 were sampled following the observation of clinical sign relating on BKD.
The 4 fish sampled showed signs of swollen, grey, granular kidney, bloody ascites, swollen spleen with granules and yellow pseudofaeces.
Pen 5 on site was noted as the pen with increased mortality compared to the rest of the site; this is also the pen that originally during routine health surveillance from the business, clinical signs of BKD were observed.
On the day of inspection, pen 1 was receiving a passive grade/targeted harvest - permission to move dead fish off site was given by FHI on 27/05/2024.
Health team visit every 3 weeks.
A few wrasse were observed on site during site inspection. No records relating to cleanerfish because site did not think that there were cleanerfish on site. Site mentioned that cleanerfish may have been transferred from Trilleachan Mhor - ~5% remaining on site. [Original PDF]

Fish came on from Lyrawa Bay (FS0054) and after slightly elevated mortality following transfer, the fish are reported to have performed very well on the site with low mortality levels since. AGD scores have also been very low.
Site has only used Tricaine for sealice counts since input. Site manager shared his observation that leps are becoming more prevalent in the water so a hydrolicer treatment has been scheduled for next month (March), alongside harvesting the site which is currently ongoing.
All harvests are deadhaul.
Majority of population appeared healthy and in good condition. A few individuals were noted across the site that displayed physical damage as a result from a hydrolicer treatment that was conducted at the end of 2021.
No moribund fish or mortalities were observed in any of the cages.

Salmon were moved from Fara West (FS1017) to Chalmers in Wk30. Mortality data is from input.
Salmon originated from Ardtaraig Hatchery (FS0648) and Yetts O' Muckart (FS0371) (mix of Stofinfisker and Aquagen). Yetts fish have been feeding and performing well. Few moribunds observed in the cages stocked with fish from Yetts (1-6). Cages stocked with fish from Ardtaraig (7-12) had high numbers of moribunds that were dark in colour, most exhibiting exopthalmia and some physical damage to flanks with visible haemorrhaging along the throat and ventrum. Fish were removed from these cages for diagnostic sampling.
Mortality events above reporting threshold:
Wks 48, 49, 51 and 52 2022 - all events attributed to poor gill health on site combined with environmental insult.
Wk4 2023 - also attributed to poor gill health and environmental insult.
Wks48 and 49 mortality events were not reported as required. Mortality notifications for these weeks were submitted retrospectively, NFA.
Last crop had a hydrolicer treatment in March/April 2022, followed by a thermolicer treatment in April 22. Current crop have only had a Salmosan treatment in July following transfer from Fara West and Tricaine for sea lice counts and sampling.

Fish came on from Fara West (FS1017). SW to SW RA available for inspection. Fish originated from Yetts O' Muckart
(FS0371) and Ardtaraig (FS0648). Site was diagnosed with BKD in August 2023 and CDN is currently in place on site
(CDN2023001). Mortalities have been low since the last inspection.
Site is currently deadhaul harvesting to Stromness before fish are taken to Kirkwall for processing. All fish waste from the site is taken by bulker to Dundas Chemicals for further processing.
Salmosan was completed in Dec 23 and a hydrolicer was on site at the beginning of April 24. No other treatments (medicinal or mechanical) have been done since the last inspection (with the exception of anaesthetic for lice counts).
The CoGP FMA is not fallowed synchronously and a RA for this was available for inspection.
There were several moribunds observed in almost all of the cages on site during the inspection, exhibiting dark bodies and exophthalmia. The moribund fish that were observed had a higher than average lice load but the lice load on the general population reflected records. The site currently has a CDN for BKD. Some also had physical damage to the flank and head which was attributed to the recent hydrolicer treatment in the 2nd week of April 24. The general population of fish that were sitting deeper in the water were difficult to observe but appeared healthy externally and were actively shoaling in the cages.
The fish sampled for VMD appeared clinically health externally and internally and had good body condition. 1 moribund was removed and opened for internal examination. No gross pathology was observed so no diagnostic samples were taken on this occasion.
The site is currently harvesting 3 days a week and is expected to be fallow in the coming weeks. No live movements of fish have taken place since the last inspection so no records collected.
Paperwork was inspected remotely on 02/05/24 by . Site inspection was completed by , shadowed by . VMD fish was sampled by under the supervision of .

The stock comes from October 2020 Stofnfiskur (Benchmark, Iceland) eggs, arrived in Mingarry hatchery (FS0145).
380,000 2021 S1 smolts were transferred to Tarbert South (The Scottish Salmon Company) in September 2021. 20,000 smolts were found dead upon the arrival of the wellboat. The suspected cause of death points to smoltification issues, even though the pre-transfer chloride tests proved that the fish were ready to go to sea.
100,000 fish remain on site split between two tanks. These fish will be transferred as 2021 S0 to Scotasay (TSSC) on the 19th of October 2021.
The site will then be stocked with the fish currently held at Loch A'Clachan (FS0627) after a 2-3 week fallow period.
The salmon were dipped at 1g, 5g, and 10g against ERM and injected at 50g with Alphaject 2:2 and PD vaccine.
The fish were then treated with formalin to prevent infections post vaccination.

On the date of inspection the site was stocked with 11 cages. The site is now on the harvest plan, one cage has already been harvested and two other cages are on starve with plans to harvest this week.
Cloudin have had a successful cycle and have incurred an approximate mortality of 5% since input. Upon physical examination of the stock, fish were observed responding well to routine feeding regimes and were shoaling well. There was 1 fish in cage 2,
2 fish in cage 5 and 3 fish in cage 6 that were observed with severe damage to the tail. Only one fish from cage 5 was able to be removed for closer examination and diagnostic samples were taken from this fish. This was the first fish with this condition witnessed by the site manager who claimed to have not seen a fish with this condition in the history of the site. Other than described above, no other clinical signs of disease were observed on site.
Cloudin has seen a spike in sea lice levels recently. The most recent sea lice count was taken on 03/02/2023 and accounted for an average of 4.02 AF. The site are planning to conduct a hydrolicer treatment as soon as possible. This will be the first intervention treatment for sea lice this cycle. Each pen is fitted with lice skirts and have historically worked very well at this site.
Sea lice figures for the cycle have remained very low up until week 4 2023. There was no physical sea lice damage observed on site during the physical inspection of the stock.

Last mortality removal carried out 13/02/2020 by divers, usually mortality removal is carried out daily using dead baskets, however severe weather over the past few weeks has prevented staff accessing the site regularly.
Further inspection carried on site under case 2020-0129 in order to inspect records not available at Croabh Haven and site equipment. CNA report issued under case 2020-0129 but copied to this case for reference.
Escape investigation
On 17th January, site staff observed structural damage to cage 4, positioned in the middle of the east grid. Divers attended site on the same day to inspect the cage further, a vertical hole in the net of cage 4 was discovered, approximately 1-2 metres in length, the hole was repaired by divers. The incident was reported to the fish health inspectorate on the same day confirming the loss of 73,600 fish. No recapture attempt was made due to the poor weather and fish not being visible at the surface. The remaining fish in the cage were then transferred to Cage 11, Cage 4 is now fallow.
The steel bars are connected to the stanchions via a bracket, fixed in place by a pin and nut. The design of the pin and nut assembly is such that the thread of the pin should be destroyed when the nut is fixed in place so that it is unable to unscrew. In this instance the nut appears to have come off, allowing the pin to come loose and the fixing to fail.
The cages installed on Colonsay are the Aqualine Midgard System model. All cages where removed from site at the end of the last production cycle and taken to Kyleakin for refurbishment and maintenance. This included the installation of the steel bars, previously dyneema ropes had been used. Refurbishment work was carried out by Specialist Welding on behalf of Aqualine, an Aqualine technician was present during the work being carried out. Following completion of the refurbishment the cages were transported in batches back to Colonsay where they were installed back at the site, this work was carried out by Mowi staff. Installation of the cages took place over several weeks. An Aqualine technician was on site for 1-2 days during the installation. After the first 8 cages had been installed, inspection showed that a number of the fixing pins had lifted out of position and some cases the nut was not in place. Specialist welding attended site and replaced missing nuts and tightened all fixings. All cages and nets where inspected by site staff and divers before fish were stocked. Dive inspection records are held on site barge and so were unavailable for inspection.
During the investigation there was no evidence of records being in place for the following:
• Product specification sheets giving details on the equipment used (specs taking into account the environmental conditions equipment will be subjected to on site)
• Manufacturing guidance documents for the installation of the steel bars.
• Works sign off records to show cages had been inspected as satisfactory prior to being transported to site.
• SOP or guidance document for inspection of cage equipment on site.
During the investigation, the conclusion section from an independent investigation carried out by Scale AQ (Aqualine parent company) was inspected. The complete report was not made available for inspection.
The conclusion stated that:
• Net fastening points were incorrect – net fastening between main rope and floating collar are on handrail post.
• Occasional use of under-dimensioned ropes (10-12mm) observed for attachment of main rope on other inspected cages.
• Incorrect fastening of nets means it does not retain brackets in absence of tendon system – causing handrail posts to detach from brackets.
Mowi staff and dive teams are inspecting the remaining 13 cages on site when weather allows, at time of inspection 8 cages had been inspected, with fixings being tightened. New steel plates are being made which will be installed on the current fixings, these will enclose the pin and bolt assembly to aid in holding the fixings in place. [Original PDF]

Following an extreme weather event (Storm Brendan) a loss of fish from pen 4 occured due to equipment failure. A pin that holds the base units that house the stanchions in the correct position on the horizontal axis failed. The base units and some stanchions had slid along the pen ring buckling the walkway due to the failure of the metal bracket. Plastic stays holding the stanchions in place had 'popped out' allowing the stanchion to lift up out of the holding bracket and resulting in the handrail collapsing into the pen beneath the waterline as well as a 1-2m tear in the net. It was reported that 73,600 fish had escaped.
A bracket has been placed around some of the pins to prevent excessive lifting. Divers have beeen onsite re-tightening the nuts (on all pens) that hold the pins in place.
Last visit to the site was 7/11/2019, partly completed an enhanced containment inspection (2020 - 0050) on the
18/2/2020 but this was completed on the mainland as access to Colonsay has been challenging due to weather and flight issues. The enhanced containment inspection was completed during this visit to the site.

Large variation in sizes within the cages, with many runts/poor dooers observed across the site. No moribund fish were observed and 3 mortalities were noted across the site. Not fresh dead so not sampled.
Fish sampled for VMD appeared healthy externally and internally.
Escape investigation -
Seal was observed in cage 5 during the inspection. No obvious breaches in containment were identified during the inspection.
Divers were called to the site and were in the cage the same day. Findings to follow.
UPDATE 08/07/22: The incident was reported to have been a result of a froyer ring connection failure. Divers repaired the 1m hole in the net of cage 5 on the same day the seal was observed in the cage. The fish were moved into four other cages on the site and the net removed for repairs. All the froyer ring connection points (16 per cage) across the site are currently being replaced. The winch dyneema lifting ropes and the tension bar bolts are also being replaced across the site.
UPDATE 22/03/23: Recommendations in relation to the above case were made for implementation by 20th March 2023.

All stocked pens were inspected with only 4 moribund fish observed across the whole site. The stocks were observed shoaling well and responding positively to routine feeding regimes. Two fish were displaying clinical signs of disease were captured in the mort sock which were removed for diagnostic sampling. Fish sampled for VMD appeared health both internally and externally.
Mortalites are ensiled on site during more normal levels of mortality, during the mortality event the site sought removal assistance from the Ben Mowi vessel which has an Ensiler on board.
Following the event, the sites company vet diagnosed AGD as the main driver for mortality. The site recently treated with freshwater from 09/10/2023 to 17/10/2023.
Sea lice levels were low at the time of inspection, the most recent treatments were Slice in may 2023 and AMX in July. [Original PDF]

Dunvegan pier. Mortality events had been reported to FHI.
No moribund or lethargic fish observed, however, low stocking densities in most cages on site as site was harvesting all cages to fallow, no intention to use site again. Ferguson transport boat on site at time of inspection removing mortalities, these were going directly in to tankers on the Ferguson boat. Large number of dead observed floating on surface of one cage, which was being emptied by Ferguson boat and divers. Due to COVID-19 physical distancing requirements, this cage was not accessed.
It was reported that CGD and jellyfish bloom were cause of moralities. [Original PDF]

Acts as nursery site for Salmon up to 1.5kg before they are moved to Ardessie and Ardmair. No harvests from this site.
Current stock from Loch Merkland and Loch Shin (Migdale smolt). Wild wrasse caught in Loch Broom.
The fish are currently on photoperiod, which seems to help diminish seal activity. Seal curtains also in place. The site experienced issues with heron predation in the winter so they have installed two bird scarers (long pole with moving fake bird attached), which appear to work well at deterring the animals.
The cloudy weather during the site inspection made it harder to see the stock, however good response was observed during hand feeding and the fish coming up to the surface appeared healthy. No moribunds or dead fish were observed on site. All fish sampled for the VMD looked healthy both internally and externally. No sea lice observed.
The site has never had to use therapeutic treatments to control sea lice and have managed to achieve a level of zero adult females throughout the production cycle using cleanerfish alone. [Original PDF]

During ECI inspection of Quoys Hatchery, inspector noticed that the ova coming onto the site were from Coutts Mill. This site was made inactive November 2016. An unannounced inspection of Coutts Mill was then carried out. Seems to be a lack of communication within the company led to this. Relevant paperwork was submitted to FHI post inspection and site was reactivated 19/11/2020. Enforcement Notice is being prepared to issue to the operator.
At last inspection the company stated that they had no plans on using the site again so it was made inactive. But brood fish from Turness (FS0451) were brought onto the site October 2019 and subsequently stripped through November to December
2019 then culled. The site was then fallow from 7 December 2019 until 1 October 2020 when more brood fish have been brought onto site from Bay of Cleat (South) FS0595 and are due to be stripped November. Company are planning to repeat this process for 2021.

Site has installed "seal fencing" on all stocked cages. This consists of SealPro netting stitched to the top of the SealPro net, approximately 1-1.5m high, attached to top net poles or additional poles. This has reportedly been very effective at preventing seals accessing pens over the hand rail, additional panels of netting have been installed around netting of each pen and extend above and below the waterline. Operator has regular discussions with Knox nets, who attended the site on 21/02/24, and are also in discussion for specifying the next generation SealPro nets to be installed for next generation of fish.
No containment issues noted at time of inspection.
2 fish sampled for VMD, both appeared in good condition. No sea lice observed on fish removed for VMD sampling. AGD gill scores have reportedly been elevated and a FW treatment was conducted w/b 12/02/24, well boat counts of stock aligned with the numbers that were expected for each pen.
2 dead fish observed across site, these were removed by site staff at time of inspection. 3-4 lethargic fish observed per pen, some deeper in the water column and displaying varying degrees of physical damage.
Site had positive results for Piscirickettsia salmonis, however these have reportedly reduced with the reduction in water temperature and no positives detected in November sampling. Vet conducted an inspection on 16/02/24, but no report was available yet for the visit.

Paramove treatment conducted in week 43, post treatment mortality to the weaker, non feeding population. Mortality has begun to decreased following treatment.
Morts; 31/10 - 8/11/22 -9 Days 6758 fish 1.18%/site lice levels at last count ; adult female - zero, total 0.33 all stages wild caught wrasse on site; Skye, Wrasse mortality has been low
Paramove treatment week 43 for gill issues. 5 slice treatments since input, last one 18/9/22
Site thermometer used as error in T146
87000 morts in October from 99235 totals morts since input.
On inspection moribund fish observed in pen margins. Lesions observed on many fish, some single deep lesions and some fish with many lesions all over body surface. Lesions appeared in August prior to mort issues and bloom.
Mortalities generally incinerated on site but with increased mortalities incinerator unable to manage. Morts are been taken whole and stored at the shore base in Loch Spelve as this site is currently not stocked, is the only site in the disease managements area and Dunstaffnage does not have a suitable shore base. Morts been collected by Billy Bowie. Transport doc are at Spelve shore base so could not confirm the final destination of morts. [Original PDF]

Currently divers are removing about 200 morts/cage/day.
There were a number of mortality disposal methods available for the two sites;
• Billy Bowie- whole in skips to Barkip Biogas (collection docs observed).
• Gogar – Energen Bio Gas- to Dunnswood Road, Cumbernauld (collection docs observed).
• They have a new well boat the Buccaness - hydrolicer and macerator/ensiler. Can hold 1000 cube of morts, current morts on- board of 200 cube. - material ensiled with formic acid. Then it will be pumped off into tankers and used as biofuel but uncertain currently of final destination. The boat was present during our visit.
• Fergusons boat for mort removal had been used but was not on site during our visit.
Collection docs were available for inspection from Billy Bowie and Gogar. Capacity for mort disposal was in my opinion adequate and staff numbers at the sites were increased to deal with the mortalities with staff being brought in from other areas. Divers were also present at the time of our visit for mortality removal.
Lice; caligus peaked wk37 at 10.37. Increased mortality had prevented treatment and there was evidence on site of lice damage on some fish.

Fish were input on site for the first time in wk17. Fish were input at ~150g and were noted to be soft as well as possess reduced amount of mucus. The stock on site originates from two hatcheries: Applecross Smolt unit and Girlsta Hatchery. The fish from Girlsta are a mix of stofinfiskur and Aquagen.
During the site inspection, fish were observed to be jumpy. In addition, a freshwater treatment and transfer was occuring to reduce the biomass on site so that in the next 3 weeks a SLICE treatment can occur. The freshwater treatment was being administered by the Ronjafisk and exposure to freshwater is ~1 hour. Transfers were to Druimyeon Bay, where 5 pens from
East Tarbert Bay had already been moved to.
From health surveillance conducted on site, 2 pens (1 and 7) were confirmed to have PRV. No clinical changes were observed and is currently not the primary suggested cause of increased mortality on site.
Caligus levels extremely high in Wk 29, 30 and 31. Micro jelly bloom occurred in the week of input, which agitated gills primarily. Then the arrival of Lion's mane jellyfish exacerbated gill issues on site further. Mild AGD observed in gills of fish.
Diagnostic samples taken from pen 1. Sampled fish were moribund and lethargic. In addition, signs of loss of equilibrium where beginning.

Mortalities have been very low throughout cycle since stocking. Monitored daily by camera. First fish likely to be harvested in the next few months.
Sea lice counts very low. Sea lice skirts were in place prior to stocking and just recently removed. Two slice treatments administered one in April and one in July - July treatment due to slight rise in Caligus numbers observed. No other treatments conducted, company generally favour freshwater for sea lice treatments, however other methods are available - chemotherapeutants and optilicer. Details of decision making process for choosing intervention not written into sea lice management plan - to look further into this.
Top nets and predator nets in place - no issues with predation except some bird pecking earlier in cycle which was prevented by tightening sagging top nets.
All records except movement records inspected by remotely.

Site inspection and paper work conducted by , observed by .
Site inspected in rough weather, visibility was poor and fish were residing deep within the pen. No moribund or lethargic fish observed during the physical inspection of the site.
Routine sea lice counts were being conducted during the time of visit, externally no clinical signs of disease was observed.
Moderate to severe gill damage was observed in most fish checked during the lice counts with most fish checked scoring high for PGD. There was a bloom of muggiaea atlantica (micro jellyfish) confirmed at the site in early October which has compromised gill health along with a touch of seasonal AGD. Staff have been monitoring the site daily for plankton levels and has confirmed that jellyfish counts in recent weeks have decreased. With the water temperature on site decreasing the site is hopeful to see an improvement in gill health in the coming weeks. Mortality has remained low and below reporting threshold for this production cycle.
The site treated with FW in week 42, Pen 3 suffered a treatment loss of 5,904 fish resulting from a handling error. Site still below reporting threshold for the week despite this loss.

Last site inspection conducted on 26/10/2022.
Additional inspection carried out due to high mortalities reported to the FHI in weeks 48 and 49 2022 attributed to CGD, AGD, and treatment loss. This had to be done remotely because of weather issues and airport strikes.
Week 48 - 6.8% 55,944 fish
Week 49 - 7.7% 58,269 fish
A bloom of Muggiaea atlantica (micro jellyfish) compromised gill health in early October, along with seasonal AGD. Mortalities began to increase in week 47 and a wellboat freshwater treatment was carried out on 6/12 as mitigation. This however, resulted in higher mortality numbers. The site switched to hydrogen peroxyde treatments in the following days (12, 13, 16, 18,
19/12), which have been more successful. All affected cages have now been treated, and will be retreated in the coming weeks.
Only one cage on site is not being treated as it's not displaying gill issues/mortalities. The fish are Aquagen stock rather than
Stofnfiskur.

Following consecutive reports of mortality, a site visit was planned for the 24/01/2023. Weather did not permit the inspection of the site on the 24/01 and was rescheduled for the 25/01. Paperwork was inspected on 25/01/2023.
A bloom of Muggiaea atlantica (micro jellyfish) compromised gill health in early October, along with seasonal AGD and most recently diagnosed with CMS. PGD however is the main cause of mortality (24/01/2023). Following a passive surveillance inspection on the 20/12/2022, mortalities continued to be above the reporting threshold. The site conducted its last hydrogen peroxide treatment on 19/12/2022, which was found to be successful. No further chemical treatments have been conducted on site since 19/12/2022. FW is planned to be the next treatment and if weather permits begins w/b 30/01/2023. The FW treatments will target pens believed to cope with handling and attempts will lastly be made in pens 1, 2, 10, 11 (worst affected).
Harvest of worst affected pens is an option. Due to weather and prioritising mortality removal from site, fish health visits have been limited since 20/12/2022, however next scheduled visit along with routine histology, bacteriology and PCR is planned for the 26/01/2023.
The stock origins are from Girlsta Hatchery and Barcaldine Smolt Unit; with primary input of fish from Langa Isle (East) in
September and one pen stocked with transferred fish from Holms Geo in November, respectively.

FHI contacted business for further information and to conduct a PSI.
The business had also previously reported increased mortality w/b 06/04/2020 - 29874 (1.77%) - attributed to post treatment losses (freshwater).
Additional weeks mortality checked: w/b 30/03/2020 - 1800 (0.1%). w/b 20/04/2020 - 3901 (0.2%)
No other peaks in mortality during this production cycle.
The freshwater treatment was for AGD, carried out using a wellboat. Treatment beginning 06/04/2020 and finishing the following week, all 20 cages treated at 2 cages per day. Poor weather during a couple of days caused crowding to take longer, with fish being left in crowd for longer than usual, thought to have exacerbated losses. Pens 9 and 10 worst affected. Mortality has fallen significantly during most recent week (w/b 20/04/20). No further treatments are currently planned.
No other underlying health issues, sea lice numbers low.

Storm Ellen struck. In a yellow warning area for high winds from Wednesday into Thursday. Wind: southerly
NO attempt was made to capture fish. The issue of recapture was discussed with local fishery boards.
There has been an increase in the number of local fishermen visiting the area. The site staff are unaware if any salmon have been caught.
Last Thursday 10:00-10:30 call from site letting senior management know that the whole group of cages in the northern half of the site were moving north. Thursday the group was secured by a well boat and tug boat. 6 pens were intact, 4 were damaged
(in the northern half of the site). Divers were in on Friday together with an ROV. Holes in pen 1 (which was written off) and 4 were detected. Four pens were harvested and morted (figures below)
Pen 1: 48,124 (total), 29,125 (dead) 18,999 (missing),
Pen 2 and 3 all harvested (morts - cage 2: 150, cage 3: 1,125)
Pen 4: 46,195 (total), 216 (morts), 16,144 (harvested), 29,835 (missing)
All harvesting on Friday and Saturday. All processed by Tuesday.
Site staff were on site on Thursday, they returned to shore early in the morning when conditions deteriorated. They could see from the cameras on site the pens were moving. The team drove north up on a hill overlooking the site and could see the pens were moving north. The cages swung around 180 degrees north west (clockwise) due to the wind coming from the south east.
The Ronja Fisk well boat and a tug were nearby and attached a bridle rope to a cage to secure the pens. All ten cages were attached to each other.
DC arrived at about 16:00. A tug was operating nearby in Loch Fyne and was called to secure the cages between 16:00-19:00.
Tug called Kingdom of Fife. Most southerly pens and grid buoy attached to tug. Ronja Fisk were also attached to most southerly cages to hold them in place over night. Team on site by about 6am on Friday. Started working to assess damaged pens at 10am. The cages were secured to the grid already. The fish were removed from the pens next. Divers arrived at 8am with an ROV at 10-11am. Took about two hours to check the pens with ROV and divers. The hole in cage 1 was repaired using a sweep net. The sweep net had a lead weight holding the bottom tought and the top was secured to the water line of the netting. Cage 4 was repaired by divers using thread to secure the holes. Fish from cage 2 were harvested first. Had to start on cage 2 as it was on the outside of the grid and the easiest to access. Once this pen was moved out of the way the other pens could be tended to. Then pen 4 and pen 3 harvested. Morts from pen 1 being removed whilst harvesting and removing fish from other cages. Morts removed using "Foover" and uplifts. The "Foover" uses jets of water to move fish into basket and then uses a ROV to bring basket to surface. Morts placed on a mort bin on work boat and either ensiled on the barge, or transferred into skips on Ferguson work boat. Once skips at shore they would have been transported to either Dundas or
Energen Biogas in Cumbernauld. Billy Bowie supplied skips and Ferguson Transport the lorries and boats to shift the waste.
What caused holes is unknown on pen 1. Pens 4 had a buoy wash into it causing a hole. The deformation of pen 1 probably meant that the net had undue stress in places that it wasn't supposed to causing a hole to rip. However this is unconfirmed.
Broken mooring ropes has been sent to Aberdeen for assessment. Multiple mooring lines snapped. Once one went that put more stress on other ropes causing a chain reaction, this is also unconfirmed. Unknown at present how many ropes snapped.
Harvesting of stock was undertaken by Ronja Fisk, Ronja Harvester and Ronja Challenger. Grip fisk and Ronja Viking on stand-by. All fish from affected pens went to Mallaig for processing. All fish to Ireland were planned to be harvested anyway.
Fish not counted on site as the pens have been ROV and diver checked and no holes were found. There are no plans to count these cages as it is thought very unlikely fish escaped without any holes detected.
No attempt made to recover fish due to safety concerns associated with bad weather. has been in touch with fisheries boards. Local people have been seen trying to catch fish using a rod and line but it is unknown if anything has been caught.
Cages moved approx. 200-300m.
WRS from the wild, LUM hatched at Anglesey (Mowi owned).
LUM and WRS were harvested out of the affected pens and were culled at Mallaig.
Mortality before the incident was slightly elevated caused by gill challenges and harvesting.
LUM came onto site at 27g-35g and some are around 120g at the time of the remote inspection. LUM are now between 27g -
120g as they have come onto site at different times
Last lice count was done on 16/08/2020 due to the site staff being busy with harvesting and dealing with latest incident.
Four damaged cages to move off the site the day of the physical inspection. These will go to Kishorn for repair. Since the aerial footage the cages have 'sprung back' into a circular or near circular shape. Nets sent to Knox base in Kilbernie for washing and repair. If the nets are not repairable they will be disposed of by Knox.
Foover removed fish into tubs on a work boat. Morts disposed off in three ways. Ensiler capacity on barge is 64,000L and that was filled up. Second route for disposal was Billy Bowie skips sitting on a Ferguson transport boat. The skips on the work boat were unloaded into Billy Bowie skips on Ferguson transport boat (each skips holds about 12 morts tubs full) and these were then taken to Tarbert where they were unloaded onto a truck and taken to either Dundas or Energen biogas in Cumbernauld disposal points. Third method was the mort tubs on a Mowi work boat were taken to the harbour where a Billy Bowie tanker will meet them to suck whole fish out of the tubs and taken to Energen or Dundas.

In the last two weeks in the area of Loch Etive 19 pens have been treated, 6 are on harvest plan and 4 remain to be treated.
Have been using well boat and trap treatments, Azasure, Salmosan and Alphamax. Currently have two wellboats for the area, one for 8 days and one for two weeks. Recent heavy and persistent rain will reduce the salinity in the loch and hopefully reduce reinfection.
Had been harvesting at an increase level but the main harvest boat was pulled by company operators (not F0456) to work on their sites so rate of harvest has been greatly reduced. Hope to be getting the harvest boat back. Currently harvesting 12-14 tonnes/day but if they get the harvest boat back this can increase to 200 tonnes a week. [Original PDF]

Business notified FHI regarding the increased unexplaied mortalities since wk 22 2023. Report of mortality noted that fish may be experiecing gill issues as a result of low DO in the loch.
During site inspection, pen 6 and 8 were noted as pens experiencing the highest mortality on site. Mortalities have only been affecting smaller fish on site; larger and passively graded fish have not been experiencing any issues. Interesingly, pens on the side closer to the shore were more affected. Only one moribund fish was observed and sampled for diagnostic testing. Fin damage on some fish were observed in pens 6, 8, 7, 10. In addition, no lesions or gross pathology was observed. Pens experiencing increased mortality have been put either on starve or partial starve to reduce stress.
Data loggers have been deployed on site to monitor temperature and DO levels. DO dropped to a minimum of 78% overnight from 06/06 to 07/06.
Two year classes stocked on site; 2021 and 2022 with fish from Rocks Lodge and Kinnaird Mill Trout, respectively. Both stocks since input have been doing well, with low mortality recorded, until wk 22 2023.
Fish removed from pen 7 for diagnostic sampling - stock origing: Kinnaird Mill Trout. Input to site on 14/4/2023.
Mortalities on site have been removed via the foover system; has been very effective. Daily removals occuring. [Original PDF]

Paperwork, site inspection and sampling by , observed by . conducted an Inspector Competency audit.
Stock details and BMP inspected 11/10/23 before site inspection, remaining paperwork completed on site on 12/10/23.
10 x 100m pens on site, 9 stocked at time of inspection. Site manager reported that site had consent for 12 cages. All pens fitted with seal pro nets, triple panel at the water line and the base of the net.
Last EC inspection was 15/05/21, SLA was conducted on 06/10/21.
Site experienced high levels of L. salmonis during autumn 2021 and Autumn 2022, this was reportedly due to algal blooms within the loch which prevented treatments being conducted. Site manager reported that August 21 the sites experienced a quick resettlement of L. salmonis, which was attributed to a failure with the filters on the treatment boat (Skamik system).
1-2 fish observed per pen, with lesion behind dorsal fin, these fish were very active and shoaling with the general population, no dead or moribund fish observed during inspection. Most recent health reports detailed no conclusive bacteriology findings for cause of lesions.
Fish in most easterly cages observed facing in to the current, which was reportedly much stronger than usual due to increase water being released down the river Awe from the power station following the prolonged period of heavy rain. All fish appeared healthy and pens away from the two pens at the eastern end of the pen group, were shoaling normally. Fish sampled for VMD appeared in good condition, with no sea lice visible.
Unsure of future plans for site at present, currently applications in for changing species on site from RTR to SAL, outcome of those applications will determine the next stocking date, at present the site is due to fallow by the end of the year. [Original PDF]

Input of fish next week. 195,000 at average weight of 200g.
Largest fish (everything over 3kg) on site being emergency harvested at the time of inspection and over the next 3-4 weeks.
Usually harvest fish at 4.5kg but having to harvest early due to pre-empting lice issues.
Reportedly a substantial lice burden. Just Leps, very few Caligus on site.
Blair Mhor processing factory has had to close down due to COVID which hindered efforts to remove fish from area.
Some evidence of gill issues consistent with a plankton bloom. Pharmaq was the company who took the samples and reported on 16/08/2021. Site staff usually take water samples and check themselves to look for plankton but have been unable to due to staff numbers. This staffing issue appears to be long term issue due to poor quality of staff joining the company.
Larger fish are experiencing a higher mortality rate.
New "Skamik 1.5" lice cleaning system used on site. The system uses brushes and jets of water to remove lice. It was used on
Skye (Organic Sea Harvest) before using in Loch Etive and reports were very good. They used it on site at Etive and lice clearance was very good and mortalities were low. Following the treatment lice numbers rose sharply on site. It is thought that there was a leak in the lice collection system that allowed lice to be discharged back into the sea, however, this was not confirmed by Skamik team
Escape: Pen 8 (S8) net lifted before treating. Alphamax bath treatment was about to be used but was aborted as the fish looked distressed during the crowd. Divers called in to check for morts after the crowding and they spotted a hole in the net, this was immediately repaired using cable ties. The hole was approximately 2m x 0.5m (no shape reported), hole 2-3m below base line. Nets are about 17m deep. Net raised by 7m before the treatment. Well boat on site on Monday following remote inspection to count fish and final notification will be sent once this has been completed. Site staff looking up and down Loch looking for escaped RTR. Some RTR caught in River Awe, approximately 40 fish caught. The fishery trust senior fisheries biologist has been in contact with the company about the catches. The site staff are currently in the process of installing seal pro nets on Etive 6. All nets in Loch will be delivered to site by the end of the financial year. They will be installed as they arrive and when staff have time. About 5 years ago there were no seal problems on site but recently there have been more seals observed close to site. Two Ortec systems being used in Loch Etive, on Etive 4 and Etive 6. Been in use for approx. two years, and there was a marked reduction in seal numbers and morts caused by seals when it was first installed, but the affect has reportedly reduced over the years. Many more seals in area being observed by staff. Etive 6 is closest to Connel bridge where most seal activity is.
Increase mortality on Etive 4 and Etive 6. Mortality on other sites in the Loch has been slightly higher than average. Divers used to take fish out but dive team was out of action for 10 days due to COVID. Boat breakdowns also hindered the removal effort. Issues with getting dead fish out of the cages and off the shore base. Biggest issue was getting fish out of the cages.
Divers always used. They had issues getting enough skips to shorebase to shift the fish. Billy Bowie and Gogar used to remove skips. Most of pick-ups were Billy Bowie. Low bridge that has to be passed under to get to the shorebase so Billy
Bowie can only use small skips to remove waste or they won't fit under the bridge. Tide is also an issue and they can't use uplifts in strong tides. Incinerator has been removed as it kept breaking down. Hoping to get a new one soon. Mass mortality
SOP submitted via email. Reportedly followed during the mortality event. Was last reviewed at end of August this year by health manager since the increase in mortality in the area. Actual procedures have not been changed, just the wording of some sections. In the future the Skamik will not be used again as it was not tried and tested. They will only use tried and tested methods to reduce lice numbers. Hoping to use a Ferguson boat in the future to remove fish directly from cages and place the removed fish onto skips on the deck of the boat. These could then be taken away by boat.
Observed daily cage inspection record kept on barge
Whole of Loch Etive not fallowed synchronously. Etive 3, 4 and 6 being emergency harvested at the time of the inspection.
Emergency harvested conducted as the site manager is pre-empting issues from the lice.
Final escape notification has been changed since the initial notification. On the initial notification it was though that the hole observed by the divers was caused by a seal. However, the reason for the hole being created has been revised and now the dive team think the hole was caused by a down weight being dropped too quickly by an inexperienced member of staff.
Currently there are many inexperienced staff on site. [Original PDF]

There have been new facilities (J building) added within the Salt Water unit, and have been on stream since December 2021.
Site details will change to reflect additions.
The majority of the fish that are transferred onto site are from the Evanachan Marine Hatchery.
In the next couple of months, site is actively trying to increase production of ballan wrasse and broodstock. In process of sourcing wild caught ballan wrasse from a fishery. Upon arrival to site, these will be put into quarantine. Previously fish have been caught from Isle of Skye and Mull.
Regarding disposal of mortalities, morts are recorded daily and removed. Upon removal they are frozen and the incinerated.
Site is looking at possibilities to ensile mortalities for future use, due to the high cost related to incineration.
Fish are transferred on and off site via Solway or Migdale Transport. No processing occurs on site.
In the nursery units, fish are fed with live feed such as artemia, rotifers and cryopreserved barnacle larvae. Then all fish are fed with various dry commercial feeds.

Fish came on from Barcaldine Smolt Unit, mix of Stofinfisker and Aquagen (cage 2 and 4) and aquagen only (cage 3). Site manager reported a significant variation in size between stocks, with the stofinfiskers not performing as well as they Aquagens.
Furunculosis, AGD and PGD have been detected on site. Fish were reported to have had lesions resulting from the infection however a course of Aquatet was completed in September and the fish have been reported to be feeding well again and gaining weight. Lesions had reportedly healed well following course of treatment.
Farmed lumpfish were imported from Ireland in December 2022 but staff struggled to remove them before a 12hr FW treatment so all were lost as a result, with none remaining on site. APHA have been made aware of this.
Wildcaught wrasse were stocked onto neighbouring Fishnish B site before being moved into Fishnish A in Dec 22. The site was also stocked with wrasse during the summer months over several inputs in June, July, August and September. Since input the site has lost ~50% of the wrasse. A total of 26,206 was input into the site, and the majority (12, 854) were lost during a FW treatment in December 22.
The wrasse that were observed on site generally appeared in good physical health. There were a handful of individuals observed across the site were slightly lethargic.
Mortality events above reporting threshold:
Wk37 2023: 4,364 (1.11%), wk38: 11,319 (2.92%), wk39: 5229 (1.39%), wk40: 4160 (1.12%), wk43: 5587 (1.54%).
Slice was administered in June, followed by a FW treatment in May, thermolicer treatments in June and July and an Aquatet treatment in September.
Moribunds were observed in all cages, but low numbers (~1-2). 5 moribunds were removed from cage 2 which was the worst affected cage in terms of mortality and diagnostic samples taken. Several poor performing fish were observed, particularly in cage 4. These were not moribund but were anorexic and some spinal deformities were noted.
Fish sampled for VMD appeared in good physical health externally, internally and responded well to feed.
Site staff informed inspector during visit that a seal had entered one of the cages on site recently. This had not been reported to the FHI as required and a retrospective notification was requested. Cage 4 was slightly mishapen which the site manager had attributed to strong currents at the site and a spell of bad weather recently. This had resulted in the top net being stretched and it had lifted away from the bottom net, leaving large gaps where predators could ingress.

Site had a Salmosan treatment in June, a thermolicer treatment was done in July, peroxide in September and Slice towards the end of September, beginning of October 21.
Fish were sitting deep in the water, but those osberved appeared to be healthy and were active. Lots of wrasse observed in the cages which also appeared to be in good health. 8,791 wrasse were input over June, July and August 21 and only 190 mortalities have been recorded since then. Site manager reported their effectiveness in keeping lice numbers low.
1 mortality was observed across the site. This was removed at the time of inspection.
Fish sampled for VMD appeared healthy and demonstrated a strong feed response. [Original PDF]

Fish came on from Barcaldine (a mix of Aquagen Elite and Aquagen). Both stocks are reportedly performing well. A small number of moribunds were observed across the site but no other clinical signs of disease were observed so not removed for diagnostic sampling.
One cage of farmed lumpfish were transferred onto site from Fishnish (A), but staff struggled to remove them and were all lost during a 12hr FW treatment. APHA have been informed. Wild caught wrasse from around Orkney, Oban and Skye were stocked onto the site over several inputs in June, July, August and September and have been performing well. ~300 mortalities have occurred since input.
Slice treatment was completed in December 2022, January, February and March 2023. A FW treatment was done in May, the thermolicer was on site in June and July and a course of Aquatet was completed in September. Fish were vaccinated against
IPN and Furunculosis while in the FW hatchery.
Biomass on site is higher than preferred. Due to the water temperature dropping significantly in the weeks following the
Aquatet treatment, the withdrawal period for the Oxytretracyline may exceed 55 days. The fish have been sampled for residues and the site is awaiting results. If the fish have withdrawn from the treatment then the site will be passive graded and 9 harvests will occur between now and the new year to reduce biomass on site.

AGD diagnosed on site and levels are remaining at moderate level.
Fish were removed from feed for a prolonged period during the summer months under veterinary instruction due to increased levels of jellyfish experienced on site
VHP, FMS and BMP all state mortalities are getting incinerated on the site barge, however, mortalities from this site and
Fishnish A are both being transferred in mort tubs back to a common skip at the shorebase before being uplifted by Billy Bowie and taken to Barkip for ensiling.
Tricaine was recorded in treatment record when Optomease was used.
Site staff informed inspector during visit that a seal had entered one of the cages on site recently. This had not been reported to the FHI as required and a retrospective notification was requested. With this said, the site was inspected as satifactory in terms of containment at the time of inspection.

Two stock of fish on site at the time of inspection from Landcatch and Applecross.
Wrasse caught from wild from around Mull. No average weight taken. All wrasse ballan caught between 12cm - 24cm. One cage not fully stocked with wrasse due to availability issues. The cages will finish stocking with wrasse soon. Artificial kelp on site.
FLS system in use on site during the inspection. The clearance of lice and survival rate is reportedly increased compared to other lice treatments. Hydrolicers no longer owned by company. FLS also used in March as lice numbers were slightly increased. A treatment was conducted in May due to AGD. Company policy is to use FLS as well as freshwater treatment if lice are observed on site prior to treatment for AGD.
Sites on Mull reportedly get PD each year. PD resistant fish are being bred in Western Isles and the plan is to stock them onto sites in the future.
Site switched from TMS to Optomease to anaesthetise fish. Switch was made due to ease of administration and safety.
Product contains benzocaine.

Site inspected after company reported increased mortalities wb 10/07/2023. All pens showing similar levels of mortality. No specific pens showing elevated levels from other pens. Cleanerfish mortality levels have not significantly increased as in the salmon stock on site. Site diagnosed with PD at the end of February 2023 but mortalities did not increase. AGD also recently high but did not show increased mortalities. AGD levels were reduced through FW treatment. Cause of recent mortalities is being put down to a combination of PD, jellyfish damage and AGD but with environmental factors being the main driving force.
Secondary Tenacibaculum also said to be driving mortality levels from recent health reports. Neighbouring site of Geasgill also had high levels of Muggiaea on site recently.
Site currently carrying out FW treatments which had started the day prior to inspection. A 6 hour FW treatment per pen is being undertaken and expected to finish within a week. Wrasse are being separated out so are not going through the treatment process. 2 pens had been treated by the time inspector was on site and looked to have improved from the stock in the remaining pens. Fish were seen to be swimming slower with slight gasping for air but wouldn't necessarily be classed as lethargic as they were responding and diving adown when approached. 2 fish were caught for sampling but only pale gills were observed. The wrasse on site did not appear to be suffering to the same extent with no wrasse observed gasping for air.

Salmon came on from the Ormsary Smolt Unit (FS0575) and Applecross (1 cage of this stock remains on site) and were performing well until a period of elevated mortality during June and July. The elevated mortalities were attributed to PD, combined with FW treatments. Mortality has since reduced and has been below the reporting threshold since wk41.
Slice treatments were completed early on in the cycle (in Dec, Feb and Mar) and only FW treatments have been conducted since.
Site normally grows to harvest, however fish were split down and 2 cages were sent to Lamlash for ongrowing. Lamlash lies in a different CoGP area (M-48) and a different disease management area (20) to Geasgill (M-37 and 16a). Lamlash is the only site in its DMA and both sites hold the same yearclass of fish. Lamlash was also fallow prior to receiving fish from Geasgill.
Wrasse that were on site at the time of transfer, were moved across to Lamlash with the salmon. A risk assessment was completed and was available for inspection.

PSI carried out following report of increased mortality by business - w/b 10/08/20: 61,188 (8.07%)
Recent transfer of fish onto site from Inchmore (FS0226). 200,000 on 13/08/20 and 105,000 on 14/08/2020.
On days of transfer site temperature recorded as 17.2 °C and 17.4 °C respectively. Dissolved oxygen levels on site were normal.
On the 14th, fish transferred on 13th appeared lethargic and mortality began to increase. Water samples showed no significant plankton levels. Examination of the fish, showed some minor gill pathology. A significant amount of vaccine was observed in the gut and increased levels of adhesion were also observed. No plankton was observed in the gut. No other pathology was observed.
Fish had recently been vaccinated at Inchmore with PD7 and a Pasteurella skyensis vaccine.
Subsequent water samples on 17th and 21st showed increasing levels of plankton with Asterionella sp and Cyanobacteria identified - 25/ml and 70/ml respectively, however by this time mortality had reduced significantly.
Mortality affected only the newly introduced stock, with a loss of approximately 20%. The mortality is attributed to a stress event, potentially influenced by the transfer of the stock, high temperatures and increasing plankton at the site.
The following week (w/b 17/08/20) mortality fell to 672 across site. The two weeks before the mortality event, mortality was 11 and 35 across the site respectively. [Original PDF]

Fish came on from Inchmore (FS0226) and Lochailort (FS1269). Fish were meant to be 65g at transfer, but were closer to
90g. Fish appeared healthy pre-transfer, however following transfer, Saprolegnia developed and mortalities began to slowly increase. Treatments of Pyceze and Aquacen have been completed to control the fungal infection.
Mortalities are incinerated on site, however large culls are stored in IBCs at the shorebase before collection by Billy Bowie and taken to Dundas or Barkip for disposal.
On day of inspection, some cages were being loaded into lorries for transport to Eilean Grianain (Carradale) (FS1176).
Inspector observed good crowding in the cages that were being pumped into the lorries.
Site is made up of 2 cage groups (Salmon Bay and Black Bay). Fish were difficult to observe as they were sitting deeper in the nets and the water was dark in colour. Selected nets were raised to aid removal for VMD sampling. Fish that were observed in the raised nets were active in the cages, however infection with Saprolegnia was evident across the site. Mortalities were observed in most cages, however few moribunds were observed. These were being removed by handnet during the inspection and were examined. Some individuals had significant fungal growths around the head, tail and flank.
Fish that were sampled for VMD were mostly healthy externally and internally, with the exception of a few individuals which had fungal growths on the body. [Original PDF]

Site inspection and diagnostic sampling could not be carried out as weather conditions were unsafe. The site is scheduled to be revisited in due course.
The site was stocked between 30/11/2022 and 07/12/2022 with fish sourced from Migdale and Barcaldine. Cages 1, 5 and 6 hold Migdale fish only and pens 2, 3 and 4 are stocked with Barcaldine only.
Following incial input to the site some post transfer mortality occurred up to two weeks post transfer. The site was treated with
FW followed by a peroxide treatment on 25/01/2023 in order to combat AGD which was confirmed by the company vet on
10/01/2023. Following treatment, gill scores for AGD have decreased and an overall improvement to gill health has been observed. Mortality onsite however is still elevated with the three cages stocked with Barcaldine fish accounting for the majority of mortality on site. Approximately 50% of the mortality on site in recent weeks have been reported having lesions, positioned around the vent and flank. Approximately 40% of the mortality accounted for in recent weeks has been recorded as having an unknown cause, where no obvious clinical signs of disease have been associated with these fish and 10% has been classified as input failures.
Most recent vet report 10/01/2023 - Positive for AGD, no other significant results. Further samples have been taken since the
10/01/2023 however the report has yet to be issued.
Mortality removal - Secured in site specific mort tubs transported to shore then transferred to SEM Energy Ltd. Most recent pick up, 07/02/2023 940kg.

Most recent fish vet report dated 06/02/2023 detailed AGD detected 7 out of 14 samples on 22/02/2023. Histology samples taken detected no further pathogens from fish sampled.
On the date of inspection the weather was fair, with good visibility into each pen. During the time of inspection, site staff were conducting routine mortality removal which allowed for closer observation of the fish onsite. Cages 1 and 6, stocked with fish sourced from Migdale (Loch Damph) were observed shoaling well and responding positively to routine feeding regimes. These fish have been at sea a little longer than the rest of the site, input in October 2022. Mortality in cages 1 and 6 have been low throughout the current production cycle at Gletness compared to the rest of the site, these fish are the largest of the site, averaging around 1 kg. 7 fish in cage 1 and 8 fish in cage 6 were observed with lesions to the flank. VMD samples were taken from cages 1 and 6, no internal signs of disease were observed.
Cages 2, 3 and 4 are stocked with fish from Barcaldine smolt unit. Mortality has been significantly elevated in these cages over the past 6 weeks, accounting for the majority of the sites mortality. Many fish were observed in these pens as having circular, uniform lesions to the flanks and around the vent. Many fish with lesions were lethargic and moribund. Less frequent behavioural signs of clinical disease observed included flashing / loss of equilibrium and spiralling. Fish from cage 5 (Migdale -
Loch Shin) displayed somewhat similar clinical signs of disease to cages 2,3 and 4 in smaller numbers, with an additional observation of mild dorsal and tail fin rot observed. 5 fish were removed for diagnostic sampling from cages 2, 3 and 5.
Gletness currently operates as a nursery site, plans are in place to transfer the current stock to Sweening Voe 3 on 22nd
March 2023.

Inspection conducted remotely via Microsoft Teams, no physical inspection conducted at site.
Two initial notification submitted in February 2021 (MSe250221SAL1 and MSe220221SAL1). During the latest event a seal was observed in the cage, and in the earlier event a hole was discovered by the net cleaning team. No fish were thought to have escaped during either event.
The company used to use a person with a MML who was deployed to sites around Loch Fyne when required. He will no longer be used due to a change in law regarding MML's
The site now has a license to use an ADD, required during a recent policy change.
Weather before both incidents was windy, but the wind was not enough to cause an issues by itself.
Fish will be harvested on Saturday from cage 9. Most recent notification.
About 38,533 lumpfish were input on the site. Left with about 2,000 over the site. Unsure exactly how the LUM have died.
Maybe due to increase procedures around within the cage e.g. net washing etc. Estimate taken from observing cleaner fish on the sorting table during grading. No moribund fish were observed during the cycle. TSSC biology team were notified but there were no moribund fish to sample.
LUM hatchery reared from Ocean Matters.
Although initial notifications for escapes were received, it is thought no fish have escaped.
All lice treatments using Hydrolicer this year, Optilicer also used last year. Lice numbers have not caused any issues.
Mse220221SAL1 - cage 10, most south westerly cage. Initially net lifted to stop fish escaping. Then a patch was placed over the hole by yhte dive team, using nylon thread to secure it. Fish moved to another cage (cage 5) as the hole was big and they had capacity on site. Hole possibly caused by the net rubbing on a bridle during bad weather (manager is 99% sure this was the cause). The bridle rope was the only thing close to the hole. Edges of the hole were frayed suggesting that it had rubbed on something. Fairly sure there was no snag as the hole did not have clean edges that you would expect from a snag. FNC8 system (flying net cleaner, distributed by Akva Group) is remote controlled and comes equipped with HD cameras and lights to see any damage. One cage is cleaned every week during which the nets are checked for damage. FNC8 travels between sites in the area (disinfection takes place between sites). External company (Inverlussa) comes in to inspect and adjust bridles at end of cycle. The company has attended since escape.
Seal pro nets will be used in the next cycle. Always been many seals on the site. They have had problems on and off for several years. They did have a contractor with an MML but no longer due to policy change.
MSe250221SAL1: possibly caused by seal. The edges of the hole were not as frayed at the first event. Little significant boat activity close to cage, so unlikely to be caused by boat handling. The hole was small but so was the seal. The seal swam out of the cage once the edge of the net was dropped and the divers chased it out. Patch placed over the hole and stitched onto net using nylon thread. Fish will be harvested out of the cage by Saturday (20/03/21), the fish will be counted off the site. Should have numbers next week. The net will not be used on site again as they are switching to seal pro nets.
All nets have seal blinds at the bottom
Although cleaner fish were on side during time when the breaches in containment occurred, it is thought very unlikely that any escaped as there are very few left in the cages and both the salmon and cleaner fish were very low in the water column and the holes were closer to the surface.

Grumbling mortality wks 37 (2020) - week 16(2021) attributed to background PD - low mortality. wk 48 2019- Percentage mortality slightly higher in company records than what was reported to FHI - 1.32% - Site manager explained that extra fish were found at end of cycle and that’s why number has changed in fish talk.
Issues with black loss (less fish retrieved at end of cycle or grade than expected) at end of cycle with cleaner fish. Site manager suspects that mortality is not being identified where cleaner fish stick to sides of pen and don’t end up in mort basket before rotting away. Site manager mentioned that efforts are being made to reduce black loss. Site are trialling new and different hide set ups and increasing the amount of hide available to Cleanerfish. This will help provide sanctuary during rough weather as well as reduce stress.
Cleanerfish mortality (last 4 weeks)

Freshwater treatment being undertaken this week using Ronja Fisk. Each cage is being treated for three hours.
More freshwater treatments in April (same time the fish were graded and split with Gigha) and August. Treatments were reportedly successful and cleared AGD very well.
Swabs taken every two weeks for AGD wk 42 mortality was increased due to lice treatment (alphamax). Not thought to be caused by treatments itself but caused by crowding of fish prior to treatment. The whole site was not treated due to issues with crowd, just 1 cage treated.
Hydrolicer used in wk 42-wk 43. Reportedly successful. Worked better than failed alphamax treatment as they aren't needed to be crowded for so long.
Biologist visited in wk 42. Taken blood samples. They noted the gills were in poor condition but lice and plankton levels were low
Caligus numbers were an issue since last inspection and were up at 13 (average per fish) in week 42 but that fell to 0.6 after hydrolicer treatment. No physical damage caused to fish
Last treatment using SLICE in July. Treatment was prophylactic as lice were not at a level that they would usually treat at. The treatment did reduce lice numbers.
LUM mortality elevated in wk 42 lumpfish mortality due to treatments and harvests.
Harvested 4 cages already. Site has been continually harvested since wk 42 and this will continue until early next year when the site is fallow. Largest fish being harvested first.

High winds prevented access to site, paperwork completed at shorebase. Site staff were unable to undertaken daily duties at site due to adverse weather. Site observed on camera's at shorebase and large swell going through site which is exposed, especially to westerly winds. Fish are fed from shorebase feeding station, they were observed shoaling well.
Site manger reported that mortalities have decreased as water temperatures have decreased, although temperatures are still reported to be over 14oC, (14.2oC was displayed by site systems at time of inspection).
Site staff controlling/monitoring feeding from shorebase reported that wrasse could be observed feeding on sea lice, where as the lumpfish didn't display the same behaviour. Bakkafrost are reported to be moving from lumpfish to wrasse for cleaner fish and these were reported to be the last batch of lumpfish that will be input to a Bakkafrost site.
The pens on the westerly side of the site were reported to be worst affected by microjellies (muggiae), although all cages suffered mortalities. From most recent health report muggiae were still being observed in the 5m and 10m trawls, although other species of micro jellyfish were now at lower levels.
Site reportedly trialled skirts to keep microjellies out of cages, these were reported to be ineffective, aeration was also used and this was reported to have a positive effect, with the numbers of microjelly fish observed in cages reportedly almost half of that outside.
WRA mortality w/b 09/10 - 13 (0.07%), w/b 02/10 - 71 (0.36%), w/b 25/09 - 255 (1.29%), w/b 09/10 - 459 (2.26%)

Most recent treatment (non medicinal) was freshwater on 16/11/2021 for 6 hours. Site manager said that this has helped reduced AGD on site. Mortality has reduced below the reporting threshold for Wk47.
Targeted harvesting has occurred, where most affected pens were harvested out. Pens 1 and 2 were harvested out wk47 and pen 7 was harvested on 02/12/2021.
Site was struggling to treat the AGD as a result of unavailable well boats to do the treatment. When freshwater became available, the treatment was limited to 3 hours, where it should have been 6 hours. As a result, lice numbers increased and fish subjected to hydrolicer treatment.

Site inspection stopped early due to an unsafe sea state, only 4 stocked pens inspected.
Site manager not present during the site inspection as he was on annual leave, the remaining paperwork was inspected remotely on 14/08/2023.
At the time of inspection, Gravir was stocked with 567,879 SAL at an average weight of 2.4kg in 12 120 meter pens. Visibility was poor on the date of inspection due to the rough sea state however clinical signs of disease were observed in some of the stocks visually inspected. Pens 1 - 4 were inspected due to mortality onsite at the time being predominant in these pens.
Approximately 10 fish were observed as being very lethargic / moribund in these pens. Most fish however were just out of reach to the hand net when attempts were made to capture due to the conditions on site at the time. Two fish from pen 1 and two fish from pen 2 were removed for diagnostic sampling. The stock were observed on camera back at the shorebase following the onsite inspection. Healthy shoaling populations of fish were observed in each pen.
The stock at Gravir were diagnosed with PD in early May of 2023 and have been recording mortality above the reporting threshold since 28/05/23. Mortality attributed to gill health has also occurred since 03/07/23 onsite, believed to be caused by an increase in jellyfish numbers in the area. Two recent reports detailing the results of health survailance on the stock have showen positive results for AGD and furunculosis, dated 25/07/2023 and 04/08/2023.
Most recent treatments were concluded on 07/07/23 and 28/07/23 which consisted of 6 hour freshwater bath treatments followed by FLS.
Freshwater and FLS treatments have been conducted regularly since December 2023 this production cycle at Gravir, initially the site was treating with freshwater using one hour bath treatments increasing to 3 hour bath treatments around March/April, and more recently to 6 hour bath treatments. The site has sustained a 100% mortality of its cleanerfish stock this production cycle. 353 wild caught ballan wrasse were input on 21/10/2022 and 70,932 Lump fish were input between 02/11/22 and
07/12/2022. From inspection of the cleanerfish mortality records, the last recorded mortality for wrasse onsite was in week 7 of
2023 and for lumpfish week 15 of 2023.
During the visit a member of site staff explained that the majority of the cleanerfish mortality was due to fish being lost during freshwater and FLS treatments. There was some doubt over whether the cleaner fish had been removed prior to these treatments. It was confirmed by the site manager during a remote inspection on 14/08/2023 that they had not been removed prior to treatment. From inspection of the Lumpfish mortality records, approximatly 22,000 fish had a recorded cause of mortalty from input untill week 15 of 2023 as AGD, the remaining stock was unaccounted for within the sites mortality records.
Site is stocked with fish from Geocrab, Applecross and Hebridean smolt.
Mortality removal onsite is usually carried out by whiteshore cockles, who remove whole fish waste from the site mort skip, positioned at the shore base. With the recent increase in mortality, excess mortalities have been removed and ensiled using the Bakkaness vessel.
REG inspection conducted as water temperature was over 14 degrees.
One issue was raised regarding the sites movement records : Movement of fish offsite to Portree (FS0708) in March 2023 was not recorded in the sites movement book. Issue raised with site manager and the record has since been updated. No further action required.

Site inspected in order to conduct a further round of diagnostic sampling following increased, further mortality at the site since the date of last inspection, which was 31/07/2023.
Gravir has been harvesting the site out since the start of August this year, during the physical inspection of the site, only one pen remained stocked with 6,000 fish. Due to the size of the pens (120m) only a small number of fish were observed during the inspection, two fish were captured and removed for diagnostic sampling. Of the fish observed during the inspection, clinical signs of disease were observed. Fish appeared extremely lethargic and moribund, some fish presented with a loss of equilibrium in their swimming behaviour and other were observed as being anorexic.
Recent health checks conducted by the companies vet revealed positive results for furunculosis and AGD, which is consistent with the diagnostic findings achieved during the last FHI diagnostic.
No treatments have taken place since the last date of inspection. [Original PDF]

Fish from Landcatch FS0575.
Site thermometer used as the battery on the inspectors died.
On physical inspection of the site, two pens were actively being lifted for harvest. The slight crowding brought fish closer to the surface where they were observed. Fish showed no signs of distress, very few lice and appeared healthy. In the other two stocked pens four and six moribunds were observed. The rest of the population were shoaling deep in water column which was hard to see. Any fish observed appeared healthy with few lice - these fish are being harvest tomorrow.
Fish for VMD samples were taken from pen 4. On examination only two caligus were observed on each fish. Internally, both fish appeared healthy but one had fat on its spleen. [Original PDF]

5 pens to be transferred to West Loch Tarbert in October due to temperature variations being too high in West Loch Tarbert in the summer while the temperature profile in Cheesebay is colder and more stable.
Lumpfish will be delivered in November to be stocked at 6-10% - from Wales
Salmosan treatment start of September 2021.
Peroxide treatment week 38 2021.
Stock from two different hatcheries. One stock performing worse than the other - not feeding well, lethargic, growing slowly and positive for AGD. Pen 12-13 worst affected, lost 3.5% in week 38.
2 small holes found in pen 12 at 0.5m depth initially thought to be caused by predator damage. Three seals observed on site. incident reported to FHI (Marine Scotland incident reference: MSe061021SAL1) and said to be caused by lumpfish feeder rubbing against already patched net. The holes were repaired upon discovery and the following corrective action will be taken: feeders will be pivoted away from the net to leave a greater distance between them to prevent future holes. In some cases feeders will be removed of cages completely where they are not required. No fish have been lost.
Site currently replacing all top nets.

Remote inspection carried out 18/05/2022. Site to be visited following reports of increased mortalities.
A number of seal attacks occurred starting from week 14 2022 which account for most of the mortalities. AGD has also been identified as the additional cause of mortality in the stock transferred from Grey Horse Channel Outer (01/04/2022) This stock has been performing poorly since input, not feeding well and growing slowly. Pens 4, 6, 7, 11, 12, 13, 14.
Harvesting has begun in April and the site is expected to be fallow by August 2022.
Mortality events: weeks 41, 44, 45, 51 & 52 2021 plus weeks 6, 14 - 17 2022 reported to FHI.
Mortalities for weeks 10 & 13 2022 not reported to FHI, see mortality events for additional info.
During the site inspection no moribunds or dead fish could be seen in the cages containing Glenfinnan stock. Some seal damage could be observed in the main population. The pens containing the fish moved from Grey Horse Channel Outer also had a small number of anorexic and lethargic fish near the water surface. Three fish could be sampled and brought to shore for further checks and upon internal examination it was found that they were sexually maturing. No gross pathology was observed. The fish sampled for the VMD looked healthy both internally and externally with minimal sea lice load. [Original PDF]

Remote inspection carried out 18/05/2022. Site to be visited following reports of increased mortalities.
The main cause of mortality has been attributed to seal predation. Complex gill disease issues have also been identified and an extended freshwater treatment was conducted in week 18, which exacerbated mortalities but alleviated the gill problems.
The site is in the process of changing nets from nylon to SealPro to try and reduce seal damage. Two nets are left to change and these are the pens still experiencing higher mortalities, the remaining cages are currently experiencing background mortality numbers.
Mortality events: weeks 40 to 44 2021 plus weeks 3, 6, 9, 10, 12, 14, 18, 20 2022 reported to FHI.
Week 11, 13, 17 not reported to FHI, see mortality events for additional info.
The weather conditions during the site inspection made it harder to observe the fish as they were deep in the water column.
Fish with seal damage could be observed swimming amongst the main population. The site staff was observed removing mortalities from one of the nylon net pens and the majority of the dead fish also presented seal bites. A small number of anorexic, lethargic fish was also seen in most cages, however these fish would swim away when approached. Three surface dead fish seen on site. Very little sea lice was observed on the fish.
The stock has been problematic since input - not feeding well, lethargic, high percentage of poor performers. Some of the fish were transferred to Grey Horse Channel in early April to thin out the cages. Three lethargic fish from this stock were removed from Grey Horse Channel and upon internal examination, it was found that the fish were sexually maturing. No gross pathology observed.
Harvesting will begin at the end of May and the site expected to be fallow by August 2022. [Original PDF]

When fish were transferred from Teisti Geo to Holms Geo in August 11th 2020, a fire occurred on the well boat. The fire cut all power to the well boat and the wells could not be oxygenated. The fish could not be removed from the wells. This caused the death of 29,000 fish.
In the last cycle of fish 28,000 (19.08%) fish died in July 30th 2018. A crash in oxygen levels over night (reportedly due to a plankton die off) caused the death of 6,500 fish. The fish were immunocompromised due to CMS. Fish killed as a result of
CMS numbered 21,500 fish.
No sea lice treatments yet this cycle.
Caligus numbers on the way up, so SLICE has been ordered for the site and they will be treating using SLICE on the week of the physical inspection.
Caligus numbers elevated, but Lep numbers still very low.
Treatment intiated on individual cages once the lice count hits average of 0.01 adults females per fish. Bath treatments not synchronised between sites.
Currently no AMA in place as regional manager recently left and there was no body to conduct meetings between the two companies.

Q3 total mortality from input to date - 35.97% (690,554). Attributed to poor egg quality/failed eggs.
29% of that total occurred during the first 5 weeks. Mortality during the last 4 week period was 0.96% (24,183). Attributed to deformaties. Ova were a mix from Ireland and Dumfries.
Q4 total mortality from input to date 29.5% (982,778). 27.94% of the total losses occurred during the first 11 weeks incubation.
Mortality in the week before the inspection was 0.19%. Total mortality over the last 4 week period was 1.35% (41,179).
Q2 total mortality from input to date 19.22% (764,733) over an 8 week period. Mortality in the 2 weeks before the inspection was 0.59% (20,758). Total mortality over the last 4 week period was 4.46% (161,403).
Peaks in mortality all occurred within the first 6-weeks post stocking so were not required to be reported. However, business has reported these and a record has been made for them.
Fish observed in the tanks generally appeared in good health with only a few individuals displaying some damage to fins as a result of nipping.

Stock on site are a mix of Aquagens from Hollyrood in Dumfries and Stofinfisker. Next egg intake is due on Friday 7th April from Stofinfisker.
2022 Q2 smolts will be moved off to Hellisay, Grey Horse Channel and Cheesebay in May 23. Parr are also moved off the site to Loch Lochy, Glenfinnan and Loch Garry.
Elevated mortality was observed in both stocks following intake, but was attributed to failed/unviable eggs and poor egg quality. Although these mortalities occurred during the first 6 weeks post-stocking and so were not required to be reported, they were reported to the FHI and a record has been made.
Slight increase in mortality following vaccinations last week, but below reporting threshold. Fish vaccinated with Micro6, PD1 and Ridgeway Skyensis.
Site treats prophylactically at first feeding, generally one treatment per week of Cress and Aquacen until the fish reach ~0.7g.
Thereafter, the site only treats fish when required. Saprolegnia is often observed post grading so Q2's received a Cress and
Aquacen treatment last week following vaccination.
All age classes on site appeared in good physical health during the inspection and were active in the tanks with good feed responses demonstrated.
Fish sampled for VMD appeared healthy externally and internally.

Inchmore is made up of a Hatchery unit, a fry unit, and an ongrowing unit. The hatchery unit consists of 4 facilities (A, B, C &
D) and the fry unit has two sub units (A&B). Between the early hours of Friday 04 to Sunday 06 August 2023 (wk 31) Fry Unit B sustained a significant mortality of 1,132,880 fish (69.67%).
The cause of this mortality is currently unknown, the fish in this unit were transferred over from hatchery units C & D the previous week. There was an initial transfer related mortality of 420,040 fish (16.85%) immediately post transfer into fry unit B, however the mortality reduced and recovered soon after the initial transfer. Following this transfer (week 30), Fry unit B received its first routine treatment of formalin and cress at the beginning of week 31 (31 July - 02 August 2023) which saw a reduction in mortality from 13,027 on Monday 31 July to 3,944 on Thursday 03 August 2023 in the unit. The same batch of formalin and cress were also used to treat other units within Inchmore which did not sustain any mortality. Following the mortality event in week 31, the current stock left in Fry unit B have recovered well and mortality has now reduced to normal levels. PCR and Histology samples were taken from fish in Fry Unit B on Friday 04 August 2023, along with water samples by
MOWI's fish health team, results of which are still pending.
Upon the physical inspection of the remaining stock in Fry unit B, fish were observed shoaling well and responding actively to the movement of the fish health inspector and the site manager whilst walking around the tanks. A few lethargic / moribund fish were observed around the mortality filter in each tank. Tank 3 and 13 in Fry unit B sustained the highest count for mortality during the mortality event in week 31 of the tanks still remaining that contains stock, so fish were removed from these tanks for diagnostic sampling.
Inchmore's ongrowing unit is made up of two smolt sub units (A & B). Another significant mortality event occurred between week 28 to week 30 within smolt unit B, which is stocked with a mix of Q3 Stofnfisker and Aquagen fish. The mortality event peaked between weeks 29 and 30 which occurred immediately post vaccination. Mortality in this unit rose from 3.89% in week
29 to 8.49% in week 30. It is thought that this mortality may have been due to some form of compromisation from high losses which occurred previously in the production cycle at incubation. In week 31 mortality in this unit reduced to 0.42%, all Aquagen tanks received a post vaccination treatment of formalin and bronopol following the mortality the previous week, fish now appear to be doing well again.
From the physical inspection of smolt unit B, fish were observed shoaling well and responding positively to routine feeding regimes. The water quality appeared slightly dull and murky which was limiting to visibility, this was due to a recent clean of the unit's biofilters. A few lethargic/moribund fish were observed around the tank's mortality filters, several fish with deformities were also observed during the inspection of this unit. Fish were removed for diagnostic sampling from tanks 5 and 8 as these tanks were most heavily impacted by mortality during the recent event.
Mortalities amounting to anything less than one tonne are incinerated onsite, any excess mortality is removed by BR solutions as whole fish waste.

Last inspection to site was a diagnostic on 08/08/2023. Records have been checked from last ECI inspection 18/04/2023.
4 hatcheries, 2 fry units and 2 smolt units
Waste - if large volumes they will get an uplift to Barkip Biogas.
Started vaccinating in week 10 and will be vaccinating for another week.
Recent Mortalities: Q3s - Wk9: 1.46% (59,472), Wk10: 0.7% (27,891), Wk11: 0.75% (29,803), Wk12: 0.42% (16,640) - all mortalities due to failed hatchings and fish deformities. Q2s - Wk9: 0.05% (2333), Wk10: 2.23% (94,888), Wk11: 1.11%
(46,276), Wk12: 1.48% (60,854) - all mortalities were due to failed hatchings (just finished hatching late last week).
Previous mortality peaks over threshold: the Q3's for 2023 Wk30: 9.39% (172,726 fish) - after the jump in mortalities the health team investigated and concluded mortalities were due to specific genetics - Only 0.9% mortalities during this week were from the stokinfisker fish.
Bath treatments - Smolts: Aquacen and Pyceze 23/03/2025 (500dd). Last year due to compromised eggs there were lots of fungus resuting in bronopol formaldehyde and Cress treatments.
Health report 20/02/2024: 1/14 tested fish was positive for flavobacterium psychrophilum. Fish were sampled and tested after some fish in Fry B were lethargic and had lesions on their sides. Fish sampled showed nothing of significance internally except lethargic fish had not been feeding.
Week 4 and 5 2024 eggs were culled out (2.5million) due to failed eggs (Aquagen stock) - lost 16.09% (302,098 eggs) in the first week on site.
Site's own thermometer used due to biosecurity
Paperwork and physical inspection carried out 25/03/2024. During physical inspection, 3 tanks in the fry units had approx. 2 or
3 mortalities. Fish in the fry and smolt units were swimming well and in tanks that were being fed (some tanks were on starve due to upcoming vaccinations), good feed responses were seen. Fish that had just been vaccinnated and transfered into the smolt units had recovered from the anaesthetic and were shoaling well. In the hatcheries, staff were picking out fish with deformaties. Fish for VMD sampling were taken from the fry units (pre vaccinaction) - all fish appeared healthy for externally and internally. [Original PDF]

TREATMENTS
Tanks in affected unit were treated with Aquacen and Pyceze Tanks 1,2,5,6,9,10,13,14,15 were treated first .Tanks
3,4,2,8,11,12 treated the following day. These tanks were seeing higher mortalities due to the delay.
Last treated 22/05/2024 - started treating 17/05/2024 - bath treatments of Aquacen (500dd) and Pyceze (0dd) in withdrawal
Reason for treatments day apart was to reduce impact on the bio filters.

The majority of the fish population appeared to be feeding and swimming well. There was some fish hanging around the sides of the tanks that appeared lethargic with signs of fungus but were responding to feed and external stimuli. Site are expected to conduct further treatments the following week. Mortalities have significantly reduced since treatments. Wk 21 mortalities were reducing by approximately up to 50% per day. Samples were not taken.

Site currently consists of 6 x 60m circles, stocked with 2 pens of 2021 year class (48,183 @ 1.407kg) and 4 pens of 2022 year class (96,121 @ 1.430kg).
No inputs to site since Jan 2023, fish are normally input to site before being split to other sites within Loch Etive. Current applications in planning system to change species from rainbow trout to Atlantic salmon. It was reported that the intention was thought to be to use the sites as nursery sites if successful in changing species. It was reported that no fish had been taken on to site with the intention of fallowing the loch (dependant on out come of planning application) of rainbow trout.
No issues noted on site, fish were observed shoaling well and no sea lice were observed on the fish sampled for VMD.
All sites within Loch Etive are now reported to have seal pro nets with triple panelling at the waterline and the base of the net.
Historically it was reported that from mid November the salinity in the sea loch drops, until spring the following year, which reduces the need to conduct sea lice treatments.
Sites have switched to Aquafarmer in June 2023, prior to this records are in a different system.

Business reported unexplained increased mortality for wk 22 2023. Site inspection was scheduled for 07/06/2023.
During site inspection, only two pens were stocked on site which were both experiencing increased mortality in week 22.
Following the inspection of stock, no moribund fish were observed. Fish were observed feeding well and no clinical signs of disease were seen so no fish were removed for further inspection . Fish in these two pens have been placed on starve to reduce stress and see if this lowers mortality.
Site had deployed data loggers, measuring DO and temperature since wk 22. Trends in data showed that DO drops to ~71% over night. In addition, from the plankton trawls conducted, there are no signs of harmful algae currently involved in unexplained mortalities. Visibility in the loch is currently limited to 3m however.
Diagnostic sampling has been conducted on site to establish reason for mortalities experienced in wk22 - on day of inspection, still awaiting results. Health visits are usually conducted weekly, but have increased following the issues experienced on site.

Increased Mortality since wk 13 2024: Following report of increased mortality within the Q4 fish, received on 11/04/2024. Initial report for w/b 25/03/2024 noted poor performers in Q4 fish. Following samples being taken on 26/03/2024 and 28/03/2024, results returned on 02/04/2024 positive for Flavobacterium psychrophilum (RTFS). Under veterinary advice, site started treating for RTFS with florfenicol on 04/04/2024 (10 day prescription inspected; end date 13/04/2024; 500DD withdrawal).
Health report from 13/03/2024 was also inspected - showed that samples were taken from fry within the hatchery, to screen for
Flavobacterium, salmon gill pox virus, IPN, SAV, PRV, PMCV and Yersinia. This increased surveillance was conducted due to health challenges in previous cohorts.
Health sampling by business was conducted 15/04/2024 and confirmed salmon gill pox virus and Costia in Q4 fish, as a secondary infection. Treatment began in all tanks on 17/04/2024 with Aquacen formaldehyde and Pyceze/Bronopol under veterinary advice (200ppm and 400ppm respectively).
Mortalities occurred in all tanks similarly; A site inspection and diagnostic test was carried out on 17/04/2024, where 5 tanks were sampled (~60 fish removed). During site inspection, the I-J tanks with fish experiencing increased mortality were inspected and in all tanks, a few fish were seen with pale bodies and darker heads. Few mortalities were observed in the top hat of the tanks. In general, fish were observed to be swimming well and noted to be feeding better.
Site is currently planning to improve and stabilise the water input from environmental influences by installing new filters/disinfection equipment. Currently there is no filtration in I-J rows, except for in the hatchery. Plans to review and improve filtration on side currently being conducted, which includes installing 10micron mesh filters, and potentially disinfection. Works should commence in May 2024.

Inspection of records carried out remotely on 29/10/2020
Caligus levels increased during July and August, resulting in increased mortality of fish, Alphamax treatments carried out reduced caligus levels significantly (91% - 97% per cage) and mortality fell as a result.
Recent mortality levels in lumpfish have been low (0.05% - 0.1%). Increased lumpfish mortality occurred during July and
August from 8% up to 25% during w/b 03/08. Mortality attributed to caligus damage and secondary bacterial infection. FHI were notified of this increase at the time. Lumpfish treated with Alphamx alongside the salmon, mortalities have subsequently fallen to low levels since September.
Wrasse mortality has been very low throughout the cycle.
Application in to MS-LOT and council for using A.D.D on site, as a contingency, seal presence around site is very low.
Site thermometer use as FHI thermometer had a battery failure.
Salmon deep in cages and difficult to observe, Lumpfish and wrasse seen near surface and appeared in good condition. [Original PDF]

Site inspection undertaken to observe procedures for transfer of stock onto site, following reports of feral farmed fish being caught in Loch Shin.
A lorry consisting of 4 tanks arrived on site where each tank was subsequently unloaded to a tank of equal size that is secured onto a transfer barge holding 2 tanks. The barge is then towed out to the site where the fish are then pumped into the pens. All pipes are securely fastened and manned at both ends with water and oxygen levels constantly being monitored. A sample of net to be used on site is taken to source site prior to transfer to ensure it is a suitable size for incoming stock.
No issues were observed with the transfer process, with all pipework securely connected. All equipment appeared in good operational order and site procedures were followed.
A total of 1,131, 247 were transferred onto the site in May 2023 for the 2023/24 production cycle. The final output of stock from the site to sea water came to 1,068,032 with a total mortality count through this cycle of 53,577 (4.7%). There was also 2 culls during grading in August and October 2023 of 9,368 fish. This then brings the total number of fish on output, mortalities and culled for this cycle to the same number of fish upon input.
The average weight of the stock on output in February/March 2024 was 97-100g. There was a small output in October 2023 with an average weight at the time of 46-50g.

Stock origins:
Kames Hatchery: pen 1 = deeper than the rest, growth best in own stock
Westmill: pen 2&3 = really aggressive feeders (larger fish on site due to larger size at input at ~350g).
Glenkens: pen 4
Seal predation was observed in pen 1 but no mortalities associated. To prevent any interest from seals around the pens, live net change occurred; nets changed from 18mm mesh to a 25mm mesh with heavier twine (Boris nets).
Site has had experience with Caligus problems previously, with some physical damage observed but treatments have been effective in reducing lice burdens on site.
Last treatment on site was on 05/05/2022: Salmosan.
Medicines are kept at the hatchery in a locked cupboard/room. Only T.M.S and disinfectant kept at the shorebase.
Any future harvests on site will occur via a new boat (deadhaul) and landed on pier, rather than previous methods of a harvesting by pushing pen to the pier and pumping fish to harvest station on the pier.
Fish sampled for VMD was observed to be in a healthy condition.

Fungus, mainly saprolegnia has been observed on site, but is only present in low numbers and is being managed successfully with no significant mortalities.
Water was very dark during the inspection so was difficult to observe the fish. Those that could be observed, appeared in good condition with only a few individuals displaying signs of fungal infection. Some fin damage was noted in most of the tanks, but manager advised that this damage had come in on the fish but was being mitigated through the use of four feeders in each tank to reduce aggression/fin nipping. He reported that this had worked well and the damage to fins as a result of nipping had reduced since the fish arrived on site.

In week 26 the site identified a large increase in numbers of micro jelly fish (Obelia) whilst conducting routine plankton checks which resulted in acute gill damage leading to an initial spike in mortality in week 26. The levels of mortality reduced in wk 27 following a reduction in plankton levels that week however mortality began to spike again in week 28 to present as a large population have developed very pale gills (anaemia from blood loss) following the initial insult which is causing on-going higher mortality. Plankton levels are currently low. The site are currently undergoing targeted harvests to reduce biomass.
Site inspected in a calm sea state, sun and little cloud cover which allowed for good visibility of the stock. From the physical inspection of the site, the visible population of SAL appeared lethargic and slow moving in all pens.

Site inspected in a calm sea state, sun with little cloud cover which allowed for good clear visibility of the stocks.
From the physical inspection of the site, a large population in each pen was observed shoaling and moving actively. There were approximately a dozen to two dozen lethargic / moribund fish observed in each pen. 5 fish displaying clinical signs of disease were removed for diagnostic sampling. The gills of all 5 fish were very pale and anaemic, indicative of a recent environmental insult, internally the fish appeared healthy, with no clear signs of disease observed.
The site is currently using both wrasse and lumpfish, both species were observed during the inspection with both stocks appearing healthy. No clinical signs of disease were observed across the site in either of the two cleaner fish stocks. Lumpfish are from Bantry (Ireland) and Wrasse are wild caught from Scotland.
In week 26 the site identified a large increase in numbers of micro jelly fish (Obelia) whilst conducting routine plankton checks which resulted in acute gill damage leading to an initial spike in mortality in week 26. The levels of mortality reduced in wk 27 following a reduction in plankton levels that week however mortality began to spike again in week 28 to present as a large population have developed very pale gills (anaemia from blood loss) following the initial insult which is causing on-going higher mortality. Plankton levels are currently low. In recent weeks the site have been conducing targeted harvest to reduce biomass, the site is now planning to fallow by the end of this month as mortality is still elevated and on-going.
Site thermometer used to record water temperature as T309 was faulty.
18/07/2023 - 3/6 fish sampled tested positive for pasturella, 6/6 positive for AGD.
Cleanerfish mortality : Wrasse - Week 28 to Week 31 was 0.41% (60 fish).

Site inspected to carry out escape investigation and enhanced containment inspection, following incident which may have given rise to the risk of escape occurring when FHI last inspected the site on 04/12/2019.
Site has been experiencing increased seal predation over the last few months, new ADD system has recently been installed on site, subsequently mortalities attributed to seal damage have reduced over the past month.
During inspection 1-2 lethargic fish were observed in the majority of cages. In cage 4 several lethargic fish with lesions visible on the flanks were observed. % fish were removed for diagnostic sampling. The remaining lethargic fish observed on site were removed from the cages and dispatched.
Fish sampled for VMD appeared healthy.
Escape investigation
During a the previous FHI inspection on 04/12/2019, a seal was observed in cage 5, the seal was then seen to leave the cage.
Divers arrived on site the same day to inspect the cage and net and discovered a hole near the base of net, approximately
25x15 mesh squares in size (nets on site have a mesh size of 15 mm). The hole was repaired by the divers. It is suspected that the hole was caused either by seal damage, or possibly by the lift-up system cone rubbing against the net during recent storm conditions Dive reports indicate that fish were observed to higher up the water column in the cage, no fish were observed outside the cage, and in the following days feed levels had not dropped. The APB completed and submitted the escape notification form to the FHI on the same day, noting that it was suspected that no fish escaped during the incident.
Divers returned to site on 06/12/2019 to inspect all other cages on site, no damage or holes in nets were found, all support ropes for lift up systems were tightened. Prior to the escape, divers inspected cages and nets on 29/11/2019 with no holes or damage observed.
At the time of the escape the site had an OTAK A.D.D. system on installed on site. Following the incident frequencies on the
A.D.D. were adjusted and an additional A.D.D. system (Ace Aquatec) has been installed on site, with both systems running.
Mortality attributed to deal damage have fallen since.
Nets on site are currently STAR mesh, these are due to be replaced with Seal pro nets at the end of this production cycle. Seal pro nets are currently being installed on the neighbouring Vuia Mor site. [Original PDF]

Kyles Vuia completed stocking for its current production cycle in December 2022 with stock from Kinlochmoidart and Jubilee
Loch Shin. The Salmon stock have performed well so far this cycle with good growth being achieved and mortality onsite remaining very low.
From the physical inspection of the stock, fish were observed shoaling well and responding positively to hand feeding at the pen side. No clinical signs of disease were observed onsite during the inspection. Fish sampled for VMD appeared healthy both internally and externally.
The site conducted its latest precautionary Slice treatment at the end of April which has been successful in maintaining low lice levels to date.
The site sustained high mortality to its lumpfish stock early in its current production cycle. Six lumpfish were sampled by the company vet on 23/01/2023 with all fish sampled showing pathology consistent with severe systemic bacterial septicaemia.
Following this diagnosis the descion was made to cull the remaining lumpfish stock on site. [Original PDF]

Site is stocked with organic fish that came on from Inverpolly (FS0264) and non-organics sourced from Inchmore (FS0226).
Organics are reported to be performing well. The non-organics have been impacted by Saprolegnia, attributed to issues with filtration at the hatchery.
Elevated mortality in wks42 and 43. Attributed to vaccination losses and fungal infection.
Fish have been vaccinated with Micro6, Micro1 PD and Pasturella skyensis.
Clinical signs of PKD were observed in fish sampled on 18/09/23, however fish behaviour and mortality trends did not raise concerns at the time. Prevalence will be closely monitored.
Dead fish and waste from the site is now incinerated on site. Culls are stored in IBCs at the shorebase before being collected by Billy Bowie and taken to Duranta, Middlesborough.
The majority of fish were difficult to observe as they were sitting deeper in the water which was very dark in colour as a result from high volumes of rain in recent weeks. Fish that were observed at the surface were infected with Saprolegnia and fungal growths were prevalent in every cage of fish stocked from Inchmore. Organics have not been so badly affected.
Staff were on site at time of inspection treating non-organic stock with Pyceze and Formalin. Moribunds and mortalities were actively being removed from the cages following treatment. Fish are due to be transferred to sea in the coming weeks.
Fish sampled for VMD appeared in good health externally and internally and food was present in the gut of all fish. [Original PDF]

2 different stocks on site, mortality consistent across the site.
Main issue on site has been gill health challenges, with one health report suggesting anaemia as well. Fresh water treatments have been conducted 20/08 9/10, 5/10/2022. Mortality has dropped after these, however it has risen again shortly afterwards.
Gills show moderate pathology, comprising lamellar inflammation, epithelial proliferation and vascular disturbances. Lesions are suggestive of a combination of factors, including infectious (Desmozoon lepeophtherii, Ca. Branchiomonas cysticola) and non-infectious (environment, handling) insults. No amoebae are detected, but some of the hyperplastic lesions present may reflect previous amoebic gill disease pathology.
Mild to moderate inflammatory pathology is noted in the heart sample; changes are suggestive of a viral infection, possibly piscine reovirus (PRV). eDNA samples are currently being processed to find out which organisms are present in the water.
Very few (1-2) moribund fish observed. Fish which appeared externally healthy were seen congregating around air diffusers.

Fish came on from Applecross and performed poorly in the first 2-3 weeks following transfer. However, have been performing really well since with low mortality and low lice numbers observed across the site. SLICE was administered in December 23 as a prophylactic and no further treatments have been conducted since. Last crop were FW treated in combination with FLS which resulted in good clearance.
Sealice counts:
Site stocked in wk50 2023. No lice counts have been above the CoGP treatment threshold since input. Previous crop went above the CoGP treatment threshold for a couple of weeks but numbers quickly reduced following FW and FLS treatments.
Company biologists attend the site every fortnight to take routine swabs and bloods. Additional samples are only taken if there are concerns regarding fish health.
Divers attend the site monthly to conduct sub-surface inspections of nets and moorings. Site has access to its own net washer so nets are also visually inspected every 10 days.
Fish on site were sitting deep in the water on the day of inspection so were difficult to observe. 1 mortality was noted across the site and no moribunds were observed in any of the cages. Box nets were deployed to catch fish for VMD sampling. The fish that were observed in the box nets were in excellent body condition. Gills appeared healthy and no lice were observed on the fish removed for sampling. [Original PDF]

The vet is on site today (21st August) waiting for histo results, and then a vet report will be sent out in the next few days regarding the current on site mortality.
Fish were observed shoaling well deeper in the water. Although a lot of fish were observed which appeared lethargic, these fish were very reactive and swam off quickly. 8 dead observed across site, with exception of cage 8 where 20 dead were observed on surface, not fresh dead, these were removed by site staff at the time of inspection. The site staff that usually operate at this site were assisting with a FW treatment at Gob na Hoe, and were due to return to site in the afternoon to do daily checks.
Jellyfish numbers increased quickly over a short period of time, resulting in the high losses week 33, mortality numbers were decreasing, but still elevated. A FW treatment was due to be conducted during week 34/35, it was hoped that this would help alleviate some of the losses due to gill issues. If the FW treatment isn't successful, the Norwegian Gannet is booked for early
September and will harvest the whole site over a few days.
Uncertain of future stocking of sites within the DMA.

Sealice treatment aboard well boat (Ronja Superior, 22/06/2020) Azasure, whole site treated but only cage 6 had increased mortality attributed to this. Fish were held for 3.5 hours. 13,699 atttributed purely to treatment in cage 6. Fish did not react well to treatment, maybe due to stressful sweep and CO2 levels was slightly higher in well reportedly caused by worsening weather conditions. Fish in well appeared blue and stressed on discharge. Mortality was increased in 3 days post treatment then returned to background level. Fish health manager took samples and tested for CMS and HSMI, both results came back as negative.
