(extended freshwater)
Causes of mortality: sealice treatment (freshwater ), tenacibaculum
SAL: Pen 8- still experiencing pressure of yersiniosis, morts are reducing. Entire site still continuing Florfenicol treatment.
It has been accepted by industry that freshwater treatments will lead to elevated lumpfish mortalities. No alternative solution was given. Site manager said that it is difficult to dewater lumpfish as a result of size and shape. Staff try to remove fish as much as possible with hand nets. Increased handling may also contribute to mortalities.
Elevated lice on site: scheduled hydrolicer treatment.

Fish input from Trilleachan Mor on 09/04/2024 (wk15). Site fallowed out previous crop on 04/04/2024. Risk assessment inspected 06/06/2024.
Stock Origin: pen 5, Lochailort, Fanad; rest of the pens, Inchmore, Aquagen
Harvests deadhaul and livehaul- to Blar Mhor.
Statutory inspection conducted following report from the business that clinical signs of Bacterial Kidney Disease (BKD) have been observed on 23/05/2024. The detailed sampling of fish by the business commenced on site following the observation of clinical signs at Seaforth (FS1042) and subsequent CDN placement. The stock origin of fish currently at Caolas a deas is noted as Trilleachan Mor (FS1118). Fish previously transferred to Trilleachan Mor originated from Seaforth (same batch of fish).
During the site inspection, all stocked pens were inspected and 5-10 lethargic fish were observed in the majority of the pens.
The majority of these fish were found to be deformed. From the ten fish that were removed, 4 were sampled following the observation of clinical sign relating on BKD.
The 4 fish sampled showed signs of swollen, grey, granular kidney, bloody ascites, swollen spleen with granules and yellow pseudofaeces.
Pen 5 on site was noted as the pen with increased mortality compared to the rest of the site; this is also the pen that originally during routine health surveillance from the business, clinical signs of BKD were observed.
On the day of inspection, pen 1 was receiving a passive grade/targeted harvest - permission to move dead fish off site was given by FHI on 27/05/2024.
Health team visit every 3 weeks.
A few wrasse were observed on site during site inspection. No records relating to cleanerfish because site did not think that there were cleanerfish on site. Site mentioned that cleanerfish may have been transferred from Trilleachan Mhor - ~5% remaining on site. [Original PDF]
