A few lethargic fish noted but fewer than one per pen. Fish removed from pens for vmd sampling appeared in good health with no internal signs of disease. Lice loads reflecting the numbers that have been reported.
Pen 4 & 13 morts slightly higher than other pens but still below reporting level but has reduced recently. PD confirmed on site but levels decreasing. LUM mortalities from 01/04 - 26/05/21 = 1,340 (2%).

Download Lumpfish on site from Ocean matters. Salmon transferred from Gometra input March 2021 - Moved in freshwater wellboat.
Cleaner fish were not transported in wellboat.
Morts - normally site boat and skipped at shore base. Due to increased morts Fergusons boat removal from site. Divers in daily to remove mort. Bakkanes - on board macerator. - numbers of fish on site will be reviewed following a fw well boat treatment.
PD runts earlier in the cycle. No SAV observed during current issues
Treatments; Salmosan treatment - June - 2 cages in wellboat. July - FW and Salmosan - all cages. hydrolicer treatment planed for this week. Hydrolicer 9/9/21.
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 Bakkanes - 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.
Mort/site/wk; wk35 0.8 %, Wk36 1.5%, Wk37 1.1%, wk38 6.2%, Wk39 4.5%, Wk40 21.96%, Wk 41 7.29% - part week.
Lice is persistent at both sites treatments are giving 85-95% clearance but resettlement is fast and treating every 3-4 weeks.
Seal ice peak 7.91 Caligus week 37.
No jellies observed in water samples. Upwell species were observed. mortality started wk 38 - attributed to environmental insult and anaemia.

Download Site inspection conducted on the 17/08/2022. 12 pens were transferred from East Tarbert Bay following increased mortality and lice burden on site. The transfers were conducted by the Ronjafisk, where the fish also were subjected to a freshwater treatment.
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.
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.
No moribund fish were observed on site, only scaling was evident. [Original PDF]

Peaks in mortality - 2022 wks45 to 49 (mort count for period- 142,565) mainly attributed to Pancreas disease and environmental conditions (water quality) reported to FHI during mortality event.
Peaks in mortality - 2023 wks11 to 30 (mort count for period- 71,447) attributed mainly Pancreas disease and environmental conditions (water quality) reported to FHI during mortality event. FW treatments were administered during this period, treatments attributed to some of the mortalities.

Records checked between 09/11/2022 to 10/06/2024 no peaks in wrasse mortality. However, 30,705 black losses was recorded for Ballan wrasse during this period.
There was 773 black losses recorded for mixed wrasse during this period.
Conducted routine FW/ FLS treatments in May 2024.
Site have noted slight increases in salmon mortalities. Suspected gill issues - gills have been scoring high with PGD. Expected to conduct FW/ FLS treatment at the weekend.
Site have observed recent increases in jellyfish numbers.
During the inspection it was observed some lethargic fish across the site, they were observed hanging to the outer edges of the cages. Fish were observed to be nosing into the tide/ current. Potentially gill related issues. 4 fish were removed for diagnostic sampling.
