Download Fish just been input from organic sea harvest. These to be ongrown to harvest. Risk assessment had been completed for the sea water to sea water transfer with satisfactory mitigation in place. FW treatment administered during wellboat transfer.
Stock is grown to organic standards so new input does not alter status of stocks held on site. The fish sampled appeared in good health with no clinical signs of disease, gross pathology or lice observed. [Original PDF]

Cleanerfish origin: lumpfish - ocean matters wrasse- scotland wild caught. No imports of wrasse from Ireland since 2021.
Health manager/vet visits sites every month. Last visit in jan 2024.
Environets; net changes happen every 14 days. The figures of cleanerfish have been readjusted 30/01/2024. During treatment,original figures of cleanerfish were not seen therefore readjusted. Recommendations on noting readjustments should be noted.
Site has not had any wrasse movements from Ireland since last inspection, however possibility that such imports may occur in next production means the surveillance frequency remains high.
Paperwork inspected remotely on 14/02/2024. During site inspection, moribund fish were observed, some with large lesions.
Two fish were able to be caught and removed for diagnostic sampling. In addition, one fish was removed for VMD sampling; it was observed to be healthy and in good condition.
