Fish came on from Knock over two inputs.
Site will be doing live harvests, with fish going to South Shian processing plant.
Fish were sitting deep in the water so difficult to observe from the cage. Observed good shoaling behaviour and feeding response on the cameras.

Download Site inspected following repeated reports of increased mortality above the reporting threshold on site from the business.
Stock details: 414741 SAL 2022 Q1 @ 2.6kg, 9/9 facilities stocked. 17398 WRS @ MVG, stocked in 9 of the pens, input on site in October 2023.
The increased mortality on site has been attributed to primarily complex gill health issues with AGD as the primary cause.
Furunculosis was also identified on site. Most recent health surveillance on 24/01/2023 validated that CGD and AGD were primary causes, and negative results were found for furunculosis, SRS, Moritella and PD. Gill swabs have been routinely taken and the site will due to finish screening the site fully again in 2 weeks.
During the site inspection, only 1 dead fish was observed, no moribunds or lethargic fish were seen. Any wrasse observed were observed to be in a healthy, good condition. Only three pens (identified as those that mortality was highest in) were inspected due to weather not permitting access to other pens. Temperature taken on 08/02/2023 was 8.25C.
Mortality, treatment, sea lice, FMS and biosecurity records were inspected. The FMS, sea lice records and biosecurity records were inspected as these were outstanding in case 2022-0461. These have been found to be adequate and have been reported on as per the case 2022-0461. Last florocol treatment for furunculosis was prescribed 21/08/2022- 01/09/2022 (all pens). Prescriptions were inspected. FW treatment was scheduled for the 09/02/2023; limited to 3 hour treatment on the well boat to allow best survival of wrasse on site. Wrasse are also creeled out prior to any treatment. [Original PDF]
