Caolas A Deas
Mowi Scotland Ltd FS1291Case Number: 2023-0475
DownloadPaperwork completed - 24/10/23. Site inspection and sampling conducted 25/10/23.
Site changed from 20 x 100m circles to 8 x 160m circles
Mortalities began to increase during end of August in to September and this was thought to corelate to drops in dissolved oxygen that the site experienced, when levels were at there lowest the site experience DO as low as 65% in August and dropping below 70% in September. The site had experienced some increase in jellyfish this summer, but not to levels that directly impacted the stock on site. The decision was made to reduce the biomass in the cages and move fish to other sea sites.
Mortalities in Pen 8 increased substantially between weeks 40 and 41, however, this was actually due to the fish in Pen 8 during WK 40 having lower level mortalities and appeared healthier being moved to Sconser Quarry on Skye. The stock in pen 8 during WK 41 was actually a split of fish from pen 1. Site keeps one of the pens fallow to allow treated fish to be returned to a different pen, due to each pen requiring 3 cycles through the wellboat to treat a whole cage.
Mortalities are currently being ensiled on site and also disposed of to White Shore Cockles.
Only medicinal treatments used this cycle so far is SLICE (January 2023, April 2023 and July 2023). A further SLICE treatment has been scheduled to being 31/10/23. Site has being using a wellboat with FW and FLS system for treatments.
Multiple infectious agents have been identified by QPCR, Piscirickettsia has been identified in QPCR samples
Sea lice levels have increased, with numbers for WK 42 2.72 adult female L. salmonis. This was reportedly partly due to disruption in FW treatments due to adverse weather. The FW treatments have recommenced on 24/10/23
LUM mortality- WK 39 - 1,660 (4.44%), WK 40 - 3,330 (9.24%), WK 41 - 3,850 (11.88%), WK42 - 3,185 (11.15%)
WRA mortality - WK39 - 2,239 (2.34%), WK 40 - 7,949 (8.5%), WK41 - 6,763 (7.63%), WK 42 - 8,558 (10.46%)
Site had two FW source inputs - Loch Garry (most of these have been moved to Sconser Quarry) and Glenfinnan
Ferguson transport vessel on site at time of inspection conducting mortality removal (uplift to basket and then transfer to storage tanks on vessel). Inter Atlantic also on site conducting FW/FLS treatment and splitting fish from Pen 7 to Pen 1.
Fish sampled from pen 7 for VMD appeared healthy. Approximately 30-40 moribund fish observed in Pen 8, 20-30 observed in Pen 4 and the remaining pens had <10 moribund visible at time of inspection. Good visibility in the cages at time of inspection
It was reported that the fish moved to Sconser Quarry have tested positive for Pasteurella skyensis, however, stock on Caolas
A Deas have continued to return negative results. [Original PDF]

Cooke Aquaculture Scotland Ltd FS0993Case Number: 2025-0418
DownloadRisk assessment inspected for CoGP management area not fallowing synchronously on a single year class basis.
The current stock was transferred in August 2025 from Fara West (FS1017) in freshwater with FLS treatment giving high sea lice clearance. Sea lice numbers have since began to increase and freshwater with FLS treatment commenced in week 40.
Treatment of the remaining 3 pens is due to be completed by tomorrow (07/11/2025).
Generally the stock on site appeared healthy and shoaling well. Approximately three to five lethargic fish were observed in each pen but all had a good startle response. Two exhibited physical damaged, attributed to the recent FLS treatment, but seemed to be healing. Sea lice levels observed on stocks reflected the sea lice count data. Some settlement damage around the caudal fin area of the fish sampled for VMD was noted but otherwise it appeared healthy externally and internally. [Original PDF]

During physical inspection of the fish, fish were shoaling well within tanks. No moribund fish observed. Fish for VMD taken from tank 3. Fish looked healthy internally and externally. [Original PDF]
Cole Deep
Scottish Sea Farms Ltd FS0489Case Number: 2025-0448
DownloadSite inspected after reports of increased mortalities which began week 43 (20/10/25), with mortality levels reported at 2.1%
(11,760). Mortality levels increased to 12% (64,080) the following week but have continued to drop in the following weeks but still remained above reporting level to present.
Health checks have identified AGD & PGD as the cause as a result of record high sea temperatures for the time of year. The water temperature was still >11oC as of 13/11/2025 but has dropped below 10oC in the last couple of weeks which has helped the situation. Recent health check have also noted a secondary bacterial infection on a few individual fish but a good appetite is still being observed.
Freshwater/FLS treatments have been conducted recently, with the most recent being carried out on 05-08/11/25. A further freshwater/FLS treatment is scheduled week beginning 08/12/25.
The site made the decision to start harvesting the fish early and are down to 3 remaining pens, 1 of which will be partially harvested 29/11/2025. The decision to completely harvest out the site will be made later based on the health of the fish. If the decision to completely harvest is made, the site will be fallow before Christmas.
Removal of moribund fish is taken place with fewer than 5 fish per pen being removed on a daily basis. Upon inspection of the remaining stock only 2-3 fish per pen were observed to be slightly lethargic but were unable to be caught for sampling. A few fish were also observed to have white caps from sea lice damage but appeared to be healing well and were seen to be shoaling well deep in the water column. [Original PDF]
Couldoran Hatchery
Bakkafrost Scotland FS0301Case Number: 2025-0422
DownloadLarger fish moving to Strondoir Bay in wk 47 - wk 48. Loaded onto lorry at hatchery then taken to Kishorn for loading onto wellboat.
Ensiled fish waste processed at Roc-Highland plant in Dornoch.
Water levels running low in late spring 2025. Water pumped from alternative loch and then the site was run on recirculation. A longer term plan to deal with the problem in the future is being put together by management team at the time of the inspection.
During inspection of the stock a small number of fish (11) were observed with saprolegnia on the dorsal fin. The fish (including the individuals with saprolegnia infection) were swimming and shoaling well. [Original PDF]
East Tarbert Bay
Bakkafrost Scotland FS1010Case Number: 2025-0425
DownloadMortality: No reported mortality events since 13/03/2023 (5 weekly, 4.05% due to PD). Wk 35 2025 (25th-31st August): 21%
(only 21 fish). At the time of this mortality, this was the last batch of fish before the current stock. East Tarbert Bay had transferred all fish on site in pen 1 (27,120) to Druimyeon Bay (FS0336), starting on the 23/08/2025. After all transfers were completed, when lifting the pen net on the 25th August, 21 dead fish were discovered at the bottom of the pen. The previous manager put this mortality down in week 35 despite the site being fallow. After reviewing the fish numbers, movement records off site and the circumstances surrounding that mortality record, it was decided that the mortality percentage for that week should be calculated against the number of fish transferred off site in the previous days. East Tarbert Bay therefore had a mortality percentage of 0.077% for week 35, 2025.
Morts ensiled and then sold for biofuel. Billy Bowie picks up and takes to Dundas.
Treatments: FW/FLS 25/10/2025 - for sealice. Alphamax/FLS: 07/09/2025 and 27/09/2025 - prescription seen, all cages treated due to sealice.
Health surveillance: Vets 23/09/2025 - Aquatic vets visit 9 days after fish transfer onto site. No issues found, signs of early maturation. Company biology team 15/09/2025 - Low PGD scores, signs of early maturation. Patogen report 10/10/25 - 19/20 positive Aeromonas salmonicida, 12/21 positive piscine orthoreovirus, negative for moritella viscosa, SAV, PDV, Pasteurella skyensis O2, Pasteurella atlantica + skyensis O1, 14/21 positive for PMCV and 7/20 positive for Yersinia.
Sealice: Sealice numbers have been low during period checked except since week 38 2025. Druimyeon Bay treated for sealice week 38 (3.6, mainly caligus) - it is theorised that during crowding the lice shed their eggs which went with the tide down to East Tarbert bay, giving rise to the increase in lice numbers. Normally treatments would be synchronous for both sites however the treatment boat was required elsewhere urgently therefore East Tarbert bay was not treated at the same time.
Treatments at East Tarbert Bay have reduced lice numbers. Last weeks figure is 0.45.
The site is currently being used as a grower site with and no full cycles have been carried out since 2021 due to mass mortality events at the time.
During physical inspection of the site only one dead fish was seen across the whole site. One exothalamic fish was observed in one pen and each of the six stocked pens had between 1-5 fish with dark colouration. In all pens the majority of fish were shoaling deeper in the water column. Of fish observed at the water surface, no lice were seen. One pen was being fed at the time of inspection and fish had a good feed response.
One fish was taken from pen 2 for VMD sampling. This fish appeared healthy internally and externally. The fish had 2 sealice on it at the time of sampling. [Original PDF]

Bakkafrost Scotland FS1233Case Number: 2025-0451
DownloadStocks on site include Q2 fish transferred from a seawater site and Q3 fish transferred from a freshwater site. Q2 fish arrived on site 12/07/2025 with Q3 fish beginning arriving on site between 22/07/2025 and 02/09/2025.
Mortality - Weeks 31 and 32, 2025 - 2.28% (11,646) and 3.29% (18,322) due to smolt transfer losses in the fish transferred from freshwater - these did not have to be reported to FHI as they were within the 6 week transfer window. Week 38, 2023 -
1.05% (9970) due to post treatment losses/AGD. Weeks 17, 20, 21 and 22, 2024 - 1.56% (3448), 2.96% (6310), 1.71% (3230) and 2.53% (4403) mostly due to PGD/AGD and post treatment losses. Numbers are low but percentage high as the site was harvesting to fallow at the time.
Treatments - Last cycle 2023/2024: Freshwater and FLS treatments in August, September, October 2023 and January, April,
May 2024.SLICE treatments in August, November 2023 and January 2024. This cycle: Alpha Max treatment July 2025. SLICE treatments August, September, October and November, 2025. Freshwater/FLS treatments August, September, October and
November 2025. SLICE treatments have been used as a preventative measure on site and all freshwater/FLS treatments were to treat AGD on site.
Health Surveillance - most recent company biology site visit 08.10.2025 - low levels of AGD and PGD seen visibly and gill swabs taken which were positive for AGD.
Physical inspection of the site was carried out on 26/11/2025 - due to adverse weather conditions all pens were inspected from the boat apart from pen 10 where a fish was taken for VMD sampling. No moribunds were observed on site and fish in pens that were being fed showed good feed responses. The fish observed in pen 10 were shoaling a couple of metres below the waters surface and the fish taken for VMD sampling appeared healthy both externally and internally and had 1 sea louse on it.
During the time of physical inspection the site was carrying out freshwater/FLS treatments on two cages.
Movement records were taken and transfer notes seen at the time of inspection and mortality and treatment records were also discussed. A remote inspection looking at all remaining paperwork was carried out on 04/12/2025. [Original PDF]

Bakkafrost Scotland FS0839Case Number: 2025-0042
DownloadSite inspected following reports of increased mortality week beginning 07/07. Mortalities on site had been attributed to PD.
During the inspection 15-20 lethargic fish observed across sites with 6 moribund fish observed within pen 4. The moribund fish were near the centre of the pen beside the top net support and were unable to be caught.
9 fish removed and examined at the shorebase, the 5 fish displaying the most significant internal signs were sampled.
Salmon on site are from two different FW sources, with the majority of mortalities occurring in one stock. A FW/SFLS treatment was conducted between 01/07 and 04/07 to cover all pens.
During routine water samples, micro jellyfish were observed and the site automatically implemented procedures to reduce the impact on stock. Numbers of micro jellyfish have reported to have dropped, but the site is still operating to procedures to address this.
A peak in mortality occurred the W/B 07/07/25 where mortalities of 66,371 (11.19%) were reported, mortalities reduced week beginning 14/07/25 to 39,114 (7.43%). The worst affected pens were Pen 4, which lost 17,827 (56%) of it's stock W/B 07/07 and W/B 14/07/25 lost a further 6,200 (45%) of the stock.
During the same period Pen 11 lost 12,362 (33%) W/B 07/07/25 and a further 7,432 (30%) W/B 14/07. At time of inspection the report mortalities for site W/B 21/07/25 (between 21/07/25 and 23/07/25) were 4,230 (0.86%) .
The site had received QPCR results the day prior to the site inspection, these identified pasturella skyensis, although no observations reported in fish sampled of signs consistent with pasturella skyensis. The site also received positive CMS results from gill swabs, but no result reported from heart sample. [Original PDF]

DownloadNext input will be cleaner fish: ballan wrasse. Wild caught most likely from around Skye.
Micro jellyfish were reported as the primary cause of the mortality, specifically Muggia atlantica.
Routine mortality is usually disposed of using ensiler on the barge. Mass mortality is being disposed of via dead haul to Pelagia
(in the Shetland Islands) and Whiteshore.
Barbed wire jelly fish observed visually with the naked eye on site (they cannot be collected using the plankton sweeps due to size).
First mention of barbs in log was 30/08. These were observed on and off until late Sept. Muggia were first observed in late Aug
2025 and have been the only species present in plankton samples since early Oct. Of recent Muggia has been at levels of 22-
80 jellyfish per m3 (since 09/10). Barbs peaked at 92 jellyfish per metre in August (30/08)
AGD was first picked up in wk 14 at low levels from clinical signs, although PCR tests were negative at this time. First picked up via PCR from gill swabs in wk 26 at low levels. Wk 27 the AGD was becoming more of a problem.
Vet report from Pharmaq on 14/10/2025: moderate levels of AGD reported. Biologist told verbally that the jellyfish damage must heal before treating AGD with freshwater.
AGD scores were at 2 (0= perfect, 5= very poor) in week 41 and remained high at 1.26 last week. Treatment started on
Monday before inspection. Treatment to last until this weekend (08/11-09/11).
Wk 35 AGD score was 1.65 which decreased to 0.53 following treatment in wk 35.
At the time of the inspection a treatment vessel was on site that had treated 5 of the 8 stocked cages. Cages 1,3 and 8 not treated yet as they were least effected. 142,845 morts this week. Mostly from cage 8 with 106,880.
Mortality worst in cages 4 and 6. Cages were treated by prioritising cages with highest mortality.
SLICE treatments carried out in weeks 33+34. Lice levels before treatments were 1.96 caligus and 0.15 for gravid leps. These figures dropped to 0.16 and 0.06 respectively.
SLICE treatment in mid-July wk 28+29. Lice levels before 0.97 for caligus and 0.28 for female leps. Before figures dropped to

Mowi Scotland Ltd FS0016Case Number: 2023-0497
DownloadLarge number of mortalities observed floating on surface of a number of pens. Site is actively removing mortalities, normal practice for mortality removal is uplift to bins and the bins are transferred to Ardintoul, the site are using the Aqua Scotia for mortality removal at present (whole fish removed from pens and transferred to tanks at pier. Mowi have also used the
Bakkaness for mortality removal with fish removed by uplift and ensiled onboard.
It was reported that the site conducted a FW treatment in mid September and followed this up with a hydrogen peroxide treatment at the beginning of October (07/10 to 10/10), the mortalities began reportedly to increase following this treatment, with pens 3,4, 7 and 8 reported to be affected initially, before all pens on site being affected. Operator has been conducting their own sampling and these results have identified CGD, they have also had Pharmaq Analytiq on site recently and the results from that visit/sampling also identified CGD, but also noted "no history of exposure to harmful phytoplankton or zooplankton despite extensive monitoring"
Site manager reported that although site has CGD, there have been no environmental issues this year. Sea lice numbers on site are extremely low with wk 44 count being 0 adult female leps, 0.01 mobile leps and 0.01 chalimus . Site currently in withdrawal for hydrogen peroxide (500 degree days) due to treatment being for gills rather than sea lice.

Ness of Copister
Cooke Aquaculture Scotland Ltd FS1043Case Number: 2025-0447
DownloadNess of Copister is primarily used as an S1 nursery site and is the only site operating within the Disease Management area
(DMA).
Mortality events had been reported to the FHI weeks 40 through to 42 and week 46. Main issue was complex gill issues, primarily AGD across the whole site. Week 47 mortality levels were above reporting level (2.74%, 30,823) but are yet to be reported at time of inspection. This is a reduction from the previous week.
Freshwater bath treatments began on site on 24/11 and aim to be completed by 07/12, weather permitting. A portion of the fish have been transferred to other sites for further growing and were given a freshwater treatment while in transit. Early indications show this to have improved their health.
On visual inspection of the site the vast majority of fish could be seen shoaling well deep down and responding well to feed. A small number of fish (5-10) per pen appeared slightly lethargic but had a good startle response so were not removed for sampling. There was a higher number of fish hanging out near the surface in 3 of the pens but this was due to them not being fed in preparation of treatment in the next couple of days.
2 fish were removed for VMD sampling and appeared in good condition with no external damage or haemorrhaging. Internal examination also showed the fish to be in good health.
The Biosecurity Measures Plan, mortality records, treatment records, sea lice records and Farm management Statement was inspected remotely on 19/11/2025. Movement records, waste transfer notes and surveillance results were inspected on the day of the site inspection, 25/11/2025. [Original PDF]
Seaforth
Mowi Scotland Ltd FS1042Case Number: 2025-0408
DownloadSite visited in response to reports of increased mortality at the site. Seaforth have reported over the 1% mortality threshold at the site between 22/09/25 - 12/10/2025. HSMI and unstable oxygen conditions have been the main drivers for mortality.
Company Vet also identified Pasteurella Skyensis on 6/10/2025. Some Gill pathology has also been identified between 6th
October and 17th October with elevated levels of AGD and PGD noted. Mortality has reduced significantly following treatments but some low level mortality is still presenting in stocks.
Following the increase in mortality at the site, a FW + FLS treatment was conducted between 14/10/2025 - 18/10/2025.
Immediately following the FW + FLS an infeed antibiotic treatment (Flofenicol) was administered which was fully completed by
25/10/2025. The site also treated with slice during the week beginning 21/08/2025.
Mortality on site has mainly occurred within pens 5, 6, 7, 8, 10 and 12. During the inspection of the site, moribund fish were clearly visible with approximately 50 - 100 per pen observed in 7, 8, 10 and 12. A healthy population of fish was also clearly visible where the bulk of the population were observed shoaling well and responding positively to routine feeding in every pen.
A 5 fish diagnostic was conduced and fish were removed from pens 8, 10 and 12 which presented the worst in regards to numbers of moribund fish in comparison to the rest of the site.

Mortality since the last inspection has been low, below reporting threshold for the last cycle and this cycle (after 2 weeks initial input) until Wk 43 due to AGD gill issues. Fish were treated with freshwater 1/11/2025. At time of inspection mortality for the current week was well below 1%.

2025. Last cycle - 2 freshwater treatments from October 2023 until the site fallowed in June 2024.
Health Surveillance: 18/09/2025 (External) - No lice seen, gills look good. Last internal company biology report 27/10/2025 - high AGD visible in most gills checked. Liver lesions on the morts are suggestive of possible pathological/environmental insult.
During physical inspection of the site water visibility was poor due to heavy freshwater runoff creating brackish water. One lethargic fish was observed but it swam off when approached. One pen was observed feeding and fish had a good feed response.
No lice were found during the lice count observation but around a quarter of the fish sampled had a low score for AGD. [Original PDF]

DownloadA remote inspection was conducted on 30/10/2025 – FMS, mortality, treatment, biosecurity, health surveillance and sea lice records were inspected. The remaining mortality and sea lice records up to 05/11/2025 and the movement records were inspected during the site inspection.
Risk assessment inspected for CoGP management area not fallowing synchronously on a single year class basis.
An ensiler at SSF Ltd mortality yard in Twatt is available but not routinely used as a method of waste disposal.
The current stock test positive for AGD (08/10/2025 third party report, 11/11 positive for AGD) and a hydrogen peroxide tarp treatment was initiated in week 42 with fish reported to have responded well to treatment. Some poor performers/runts were noted on input and were suspected of being failed smolts. The fish were vaccinated for IPN but a pooled sample of poor performers/runts tested positive (08/10/2025 third party report). Individual samples of the general population were taken and tested negative (03/11/2025 third party report, 8/8 negative for IPN).
The site is expected to be spilt down in January 2026 to Puldrite (FS0813) and fish will be transferred in freshwater.
Generally the stock on site appeared healthy and shoaling well. Two lethargic fish were observed across the site and both had a good startle response. Fish sampled for VMD appeared healthy externally and internally.

DownloadFish on site were transferred from Torhouse Mill, Glenkens or Loch Poolteil.
Site has been dealing with increased mortality for 12weeks, mostly attributed to complex gill disease following jellyfish damage. In addition, Tenacibaculum sp. has been identified on site. Under veterinary advice, reduced feeding and a starve period was put in place.
Last treatment on site was conducted from 27 to 31/10/2025 - Salmosan to target increased lice levels on site.
Result of Surveillance: Jellyfish damage with secondary infection with Tenacibaculum spp. (confirmed through PCR by
Patogen on 22/08/2025 and 03/10/2025). AGD, Branchiomonas custicola, Paranucleospora theridion all positive following samples sent to Patogen 29/10/2025.
During site inspection, 15+ moribund/lethargic fish were observed in each pen. Some fish were observed to possess lesions, with some of these lesions also seen in the general population deeper in the water column. 4 moribund/lethargic fish were removed for diagnostic sampling. All fish were observed to have gills in poor condition, with three fish also exhibiting lesions.
Discrepancies in the mortality events was observed between what was notified to FHI and the records held by the site.
Specifically from Wk 33 to WK 44. Updated notifcations have been provided to correct the mortality events we were notified of, which now match the records held by the site. The majority of changes are related to the %. Wk33, Wk36 and Wk37 notifications have had their count changed to 2430, 6780 and 6372 respectively from 3165, 5090 and 5588. Explanation was provided for the % errors: a software issue had caused the failure of removing culls relating to sea lice counting to occur. The business has removed a function that was causing this error and therefore going forward no issues should occur again. For
Wk33 mortalities, an old mortality notification template was used, meaning that an old incorrect count of mortality was noted. A reminder was provided to ensure that future mortality notifications contained correct information prior to submission. [Original PDF]

Pen 8+9 planned to be harvested out on 10/11/2025.
Last treatment was a FW + FLS from 17/10/2025 to 20/10/2025.
During the site inspection, between 25+ lethargic fish were observed in pen 8 and 9, with ~10 in all other pens. No noticeable lesions were observed during the site inspection, but some fish showed signs of healing lice damage on heads. Five moribund/lethargic fish removed and diagnostic samples taken.
Wrasse mortality (last 4 weeks): Wk44; 801, 3.59%;Wk 43, 947,3.48%; Wk42, 655,2.35%; Wk41,215,0.77%; Wk40, 645,
2.25%. No lumpfish in this production cycle.
Discrepancies in the mortality events was observed between what was notified to FHI and the records held by the site.
Specifically, Wk42 (notified of 26952, 9.72%; records show 17980, 6.47%) and WK41 (notified of 4355,1.55%; records show
3827 1.36%) 2025. Explanation was provided on the reasoning for these discrepancies: an amendment had been made as after counting the fish in the harvest tubs there was found to have been an overestimation of the mortality numbers.The site records are the correct and up to date figures. Updated notifications have been provided (12/11/2025). [Original PDF]

DownloadSite inspected following mortality reports above the reporting threshold.
5 cages still holding stock on site, decision on whether to hold fish to scheduled harvest date (July 2023) or bring forward the fallow date was due to be made WK 19.
Site experienced a peak in mortalites following FW treatments by wellboat (Intercaledonia). The FW treatments were reported to be 12 hours (between 08/04/23 to 15/04/23). Following the increasing mortalities samples were taken and Aeromonas salmonicida was the primary pathogen identified - vet report stated "Aeromonas salmonicide is likely to have been present during freshwater bathing, which alongside handling stress and/or previous handling through the cycle has resulted in a severe infection challenge".
The majority of mortalities are acute infections, with these fish showing no or very few external signs of furunculosis. The fish with acute infections displayed various internal signs, mainly haemorrhaging on the swim bladder, enlarged spleens and clear ascites. The fish with chronic infections displayed external signs including furuncles
Vet from Pharmaq Analytiq was on site during site inspection to conduct a follow up visit to previous sampling trips. They inspected recently removed mortalities and examined these externally and internally. They also opened a number of lumpfish mortalities.
Cleaner fish on site are from Otterferry, unsure of future stocking plans for cleaner fish, however, if they are to be used they will be source from within Scotland.
Fish on site vaccinated with PD3 vaccine - Salmon pancreas disease, infectious pancreatic necrosis and aeromonas salmonicida. Fish vaccinated at Barcaldine.
