FHI on site 16/11/2022, morts were on the increase but weekly total numbers were not known as morting was ongoing. Lethargic fish observed in pen 4 five fish diagnostic sample taken. FHI to monitor. Mortality rate % was corrected from 2.77 on original report to 2.72 on 23/01/2023 after data resubmitted. Reason being a historical stock balance error on a supporting spreadsheet where original figure was taken.

Case Number: 2020-0464


Download Inspection of records carried out remotely on 29/10/2020
Lumpfish mortality has been low since input. Additional lumpfish input due for November
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 used as FHI thermometer had a battery failure.
Salmon deep in cages and difficult to observe, Lumpfish seen near surface and appeared in good condition. [Original PDF]

Case Number: 2022-0483


Download Micro jellyfish bloom during September, confirmed as Muggiaea atlantica. No morts directly attributed but some damage to gills likely.
AGD reported to be an issue with P4 being worst affected. A number of lethargic fish were observed in P4 and five were removed for diagnostic sampling. Site is below the mortality reporting threshold however it is likely that levels will be above the threshold by the end of the week.
All dead haul movements offsite. [Original PDF]

Peaks in mortality: 14/11/2022 - 2.72% to 26th December 2022 - 4.26% total of 520,638 fish lost due to AGD, complex gill health, jellyfish. These were all reported to FHI. 2023: 1.2% in march but within 6 week stocking period.
Pen 2 (S0) - CMS Pen 4, 6 & 7 HSMI (PCR) but no clinical signs
Ocean matter and otterferry were the sources of lumpfish populations. Currently only 2 cages are stocked with lumpfish.
Lumpfish mortality was checked and no large mortalites to note.
Ensiler has been out of action since 16th December 2022. Morts since then have gone to Invertote to be ensiled.

Alphamax - 18/07/2023 to 21/07/2023 whole site due to caligus problems. Site one week late in treating due to treatment boat breakdown.
Freshwater in December 2022 for gills, middle of February for gills and end of June - for gills/lice, preventative for AGD
Currently upgrading the seal pro nets specification - extending (doubling) panel round the side. Extra patch on lock off area
(hang from 5m ropes)
Seal fence is attached to 2.5m poles (7 or 8ft high) and stitched onto net. When carrying out treatments etc. the seal fence is lowered and remains stitched to the net.
During physical inspection of site, a couple of moribunds were observed on each cage. A small number of fish were jumping on each cage with the majority of the population shoaling deeper in the water column. Some 'whiteheads' were observed - lice damage due to alphamax treatment being delayed.
When sampling VMD - fish from cage 6 appeared healthy both externally and internally with approx 2-3 caligus lice load each.
The fish from cage 2 also appeared healthy externally and internally with 4 caligus lice load. However it was noted that the liver colour in the fish from cage 2 was very pale. No other abnormalities noted and the site had low mortalities along with no signs of clinical disease other than the few moribunds. [Original PDF]

Case Number: 2024-0039


Download 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.
Site has full suite of medicinal treatments if required, but site have been using FW, which was reported to give good clearances.
