Case Number: 2022-0227


Download This is Shuna points first inspection as part of the surveillance program. The site was registered in March 2022. It is replacing
Shuna FS0695 - Which will no longer be operated, under the conditions of the new sites licence.
No Cleanerfish mortality reported since input in week 24.
FISA - name of new net manufacturer
Enhanced containment inspection conducted as the site is newly registered.
Recommendations for improvement were made by 01/12/2022. [Original PDF]

Case Number: 2023-0029


Download Stock origin: Barcaldine Smolt unit, Stofinfiskur
Wrasse on site, wild caught from Orkney. Mortality on site low but furunculosis was observed on site and is attributed to spikes in mortality. Wrasse mortality since input- 5124
An inspection of the site was scheduled for the 08/02/2023 following repeated weeks of increased mortality above the reporting threshold. On site, pens 3, 7 and 8 were highlighted as the pens that had the highest mortality on site. Few moribund fish were observed in the pens, but those that were seen were lethargic and moribund. White ring-shaped lesions were also observed in some fish but only two were able to be caught for sampling with such lesions. 5 fish in total were removed and sampled for diagnostic purposes; 2 fish from pen 3, 1 fish from pen 8 and 2 from pen 7.
VMD samples taken from pen 3 and pen 8. Fish sampled were observed to be in a healthy condition. [Original PDF]

Dead fish incinerated on site. Contingency measures when excessive mortality experienced - material collected by Ferguson
Transport (boat and tankers) for disposal at Barkip, Dalry - not used this method on site since last year.
Recent mortality main causes associated with CGD and bacterial lesions.
Mortality - 46% since June last year, 54% since smolt input. 20.7% mortality in wrasse since input - attributed to handling / wellboat treatment. Currently mortality in wrasse up to 88 per week for site - last 11 weeks lost just over 300 fish
Site suffered extensive mortality last year as a result of micro jelly and algal blooms. There is still some continuing impact from those events with fish suffering from CGD and undergoing regular treatments.
Ongoing FW treatment for site to end 19 May, undertaken using the Inter Caledonia. AMX treatment 13/14 April - cages 7&3.
FW treatment for gills and lice
Stofinfisker stock reported to lack tolerance to treatment / challenge and handling.
One cage (cage 4) moved to Dunstaffnage FS0299 - to free up space for treating and discharging fish following treatment.
>1% weekly mortality - week 39-42 (2022); 48-52 (2022); 1-6 (2023); 9 (2023)
