CNA/ESC Inspections on 17/03/2021 and 30/10/2019
Mooring works ongoing, winter check in September.
Site monitored by cameras above and below water from feed centre in Loch Boisdale. Generally able to get out to site in rough weather but working on the cages can be difficult due to large swell. Group formed for exposed sites to share experience with sites from Canada and Faroes. Only other Scottish site in this group is Colonsay.
Lumpfish stock almost gone due to two 12 hour FW treatments. Issues with Pseudomonas, treated with Florocol in June 2021.
Stocked in Erisort, transferred with the fish in wellboat from Erisort in FW for 6 to 8 hrs. Farmed juveniles from Ocean Matters.
Not graded out prior to FW treatment, hand netting some lumpfish out during crowd. No facility to separate cleanerfish from salmon. 21,670 fish died due to handling and lice treatments and 9,307 due to Pseudomonas in August (88.06% mortality).
Input count 47,948 - total mortality until August 43,746 (91.2% total) - reported to APHA.
Not taking fish from freshwater sources, just growing fish on from other SW sites. Not mentioned in FMS.
