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]
