Case Number: 2024-0049

Download Site transitioning from 12 100m to 9 120m - only 4 x 120m circles on site right now.
Fish arrived on site 20th September 2023
Treatments this cycle: Just finished SLICE - 13th-19th Feb. Freshwater 11th Dec AGD.
Last cycles treatments: Paramove (14-16th July then 11-12 Sep 2022) , SLICE (8-14th August 2022), thermolicer (Nov/Dec
2022)
WRS mortality: In 2024 up to wk5 only 64 fish. End of last year WRS mortality was larger due to freshwater treatment Wk 44 -
118 , wk45 - 275, wk46 - 364, wk47 - 156, wk48 - 233, wk49 - 90, wk50 - 921, wk51 - 78.
WRS stocked 27/10/2023 (total 3394) and then 3 small shipments in November 2023 (1395). Large wrasse mortality during wk50 2023 (921 fish, approx. 26%) due to freshwater treatment on site. Wrasse were put through with the salmon during the freshwater treatment due to the need to also be treated for AGD. As per the company's cleanerfish booklet the freshwater treatments were shortened to 3 hours to try minimise any mortality.
Sealice: Last cycle Adult females were above 1 between Wk3-Wk9 2023 (Thermolicer in week 10) and then Wk22 2023 and above 2 (2.07) in Wk23 2023 - fish had CMS and lice levels were 0.9 in wk24 due to harvesting out of fish.
FMA going to be reviewed in April. The FMA is not fallowed synchronously on a single year class basis but an appropriate risk assessment exists.
The 9 fish taken for VMD samples appeared healthy both internally and externally. Sealice levels observed were low apart from two gravids observed on one fish from cage 9.
Due to bad weather (high winds and large waves) only small sections of each pen were observed from the walkway - the rest was observed from the site workboat. Fish were observed shoaling slightly deeper In the cage. Fish had a good feeding response.
Remote inspection for the majority of the paperwork was conducted on 21/02/2024 with the rest including the physical inspection of the site and VMD samples taken on 27/02/2024. [Original PDF]
