Inspection reports

Case Number: 2023-0046


Download Salmon came on from Duartmore and Loch Na Thulle in April 22.
An input of wild caught wrasse was received over several inputs between June and September 22. Total input was 17,700.
Only medicinal treatments conducted were SLICE in June and August and Paramove in September, October and November.
All other treatments have been FW. Site reported a good clearance of lice following treatments.
Potential broodstock are moved off site to Outer Bay (Loch Droighniche) (FS0671) towards the end of the year.
Mortality above reporting threshold:
Wk51 2022: 11,123 (2.69%)
Wk50 2022: 14,754 (3.46%)
WK48 2022: 17,966 (4.01%)
Wk47 2022: 6,306 (1.39%)
WK46 2022: 8,813 (1.9%)
WK44 2022: 20,025 (4.12%)
Wk43 2022: 7,838 (1.59%)
Wk42 2022: 5,667 (1.14%)
Wk40 2021: 387 (4.77%)
Wk39:4,604 (10.18%)
Wk38: 7,716 (10.98%)
WK37: 11,133 (10.23%)
WK36: 16,036 (12.02%)
Wk35: 14,452 (9.24%)
WK34: 4,735 (2.63%)
WK33: 3,936 (1.79%)
WK32: 3,249 (1.36%)
WK31: 2,958 (1.22%)
Mortalities during both cycles were attributed to PD and AGD on site, exacerbated by harvesting.
The general population of fish on site appeared in good physical health. The fish in cages 2 and 15 are targeted by the local seal population and physical damage was evident on these fish. A seal was observed in cage 15 during the inspection. Divers arrived on site while inspector was present. No hole was discovered in the net at the time of inspection. An enhanced containment inspection was completed while on site.
The fish in cage 4 also had some physical damage observed, however this was instead attributed to a recent FW treatment, rather than seal damage.
Fish sampled for VMD appeared in good physical health on examination. [Original PDF]

Download Spring 2024 input - pens 3 & 13 from Duartmore (FS0770). Pens 9 & 14 from Loch Snizort East (FS1309) transferred in week 35
(freshwater treatment during transfer). The Loch Snizort fish will be harvested out by the end of October and the Duartmore fish will be transferred to Outer Bay (FS0671) in November (freshwater treatment planned for transfer).
Recent Mortalities: SAL Week 42: 1.35%; Week 41: 0.77%; Week 40: 0.79%; Week 39: 0.4%
WRA Week 42: 1.03%; Week 41: 0.38%; Week 40: 0.11%; Week 39: 0.27%
Salmosan treatment week 42. Elevated mortality in week 42 associated with the treatment.
The site was visited following elevated sea lice numbers reported by the company (10.39 adult females/fish in week 35). The numbers have decreased to below 2 adult females/fish in weeks 39-41 and no counts were conducted in week 42 due to the Salmosan treatment being carried out, however sea lice counts carried out during the inspection suggest that the average number of adult females/fish will be above 6 in week 43. The site is hoping to accelerate the harvesting of the Loch Snizort fish and the transfer to Outer bay so that the site can be fallowed earlier than originally planned.
The main population appeared in good condition, shoaling deep in the water column and with a good feeding response. Some lethargic fish were observed (max 2/pen) and no dead fish were seen on site. Skin abrasions along the flanks and head damage could be observed on these fish and on a small amount of the main population. No fish with red heads observed. The fish removed for the sea lice counts had some evidence of skin damage, especially between the anal and pelvic fin, however there was evidence of treatment/cleanerfish clearance as most of these areas were clear of parasites. The fish sampled for the VMD appeared healthy both internally and externally. [Original PDF]
