Site inspection undertaken to observe procedures for transfer of stock onto site, following reports of feral farmed fish being caught in Loch Shin.
A lorry consisting of 4 tanks arrived on site where each tank was subsequently unloaded to a tank of equal size that is secured onto a transfer barge holding 2 tanks. The barge is then towed out to the site where the fish are then pumped into the pens. All pipes are securely fastened and manned at both ends with water and oxygen levels constantly being monitored. A sample of net to be used on site is taken to source site prior to transfer to ensure it is a suitable size for incoming stock.
No issues were observed with the transfer process, with all pipework securely connected. All equipment appeared in good operational order and site procedures were followed.
A total of 1,131, 247 were transferred onto the site in May 2023 for the 2023/24 production cycle. The final output of stock from the site to sea water came to 1,068,032 with a total mortality count through this cycle of 53,577 (4.7%). There was also 2 culls during grading in August and October 2023 of 9,368 fish. This then brings the total number of fish on output, mortalities and culled for this cycle to the same number of fish upon input.
The average weight of the stock on output in February/March 2024 was 97-100g. There was a small output in October 2023 with an average weight at the time of 46-50g.
Transfer of fish onto site observed on 18/06/2024. Paperwork completed remotely on 02/07/2024. [Original PDF]
