Inspection reports

Case Number: 2022-0128


Download Wrasse mix of wild caught (Skye, Dorset, Cornwall) and farmed (Otter Ferry).
Three pens stocked. The weather was calm and sunny and the fish were being hand fed during the site inspection so they could be observed well. The fish were in great condition with no signs of damage and very little sea lice could be seen. Not all of the fish are selected for broodstock so some of the population is currently being harvested.
Sea lice only assessed visually so no records available. No treatments have been necessary since the site has started stocking broodstock. The fish had sea lice issue last summer at Clashnessie Bay, so they were temporarily transferred to
Sound of Harris before being moved to Outer Bay in December 2021. The movement had been risk assessed and the fish have not had sea lice issues since. [Original PDF]

Case Number: 2025-0145


Download Fish transferred in December 2024 from Loch A Chairn Bhain (FS0621) and Clashnessie Bay (FS0933).
Wrasse (wild) transferred in April 2025 from Loch A Chairn Bhain (FS0621) and Loch Laxford (FS0067).
Good visibility into the pens, no predator damage visible on the fish. Fish appeared in good condition and no clinical signs of disease were observed.
No treatments carried out on site. Sea lice checks carried out visually without removing the fish from the pens to minimise stress on the broodstock. [Original PDF]
