Wrasse mix of wild caught (from GB) and farmed (Otter Ferry).
The site is composed by two pen groups: Reintraid and Torgawn. One dead runt was observed during the inspection and 6 fish with tail damage, possibly caused by seals as the farm manager explained they have been suffering from predation lately.
They have tried to increase the tension of the predator netting to help mitigate the issue. These fish were swimming very actively within the pens. The main population displayed good feeding response and looked healthy, with minimal sea lice load.
The fish sampled for the VMD were in healthy conditions and no sea lice was observed on them.
Sea lice counts (adult female/fish) in week 15 2022 were 1.6 so the site is currently being treated with Salmosan (weeks 16 &
17). [Original PDF]
