The fish were input growers from Wick of Belmont and input to site in April 2022. Plans to begin harvesting end of December
2022 and be fallow Jan/Feb 2023.
ROV system used to collect and check morts on site. All harvests on site conducted via deadhaul. Fish are then transported by bulk tanker to the processing plant. All movements off site are related to harvests.
During site inspection, 1 to 3 fish were seen in majority of pens that were lethargic. Upon inspection of stock during lice counts,
AGD visible and severe in some cases as well as informed that low level CMS has been observed on site. Lice levels increasing in the area due to temperature and increase in wild fish. Site plans to treat for lice and gills in October as a precautionary measure.
