Jelly fish bloom, destocking through harvest
Aeration has been deployed to reduce the number of jellyfish entering the cages and to increase water exchange. Feeding was also suspended during the bloom and mortality appears to have decreased this week, although there is still a high number of jellyfish in the area. FHI to monitor.

All mortality events have been attributed to poor gill health (CGD) combined with FW treatment losses in Wk48, 49 and 50
2023. Wrasse mortality since input for farmed stock was 45.69% and 27.28% for wildcaught stock.
Average adult female leps combined has remained below the CoGP treatment threshold since last EC inspection in April 2022.
Two batches of fish received onto site. One input in February 23, followed by a 2nd input in April 23 (within 6 weeks of each other). A mix of Fanads and Aquagens are currently on site and all came on through Barcaldine and Fada.
Site is stocked with a mix of farmed and wildcaught wrasse and site manager reported them to be effective at controlling sea lice on the site.
Lesions have been observed on some fish across site but appear to be healing well. Fish are being fed a skin assist diet to aid recovery and will soon move onto a Resist X diet to support gut function.
SLICE was administered in February 24, following a peroxide treatment in Nov 23.
General population of fish on site appeared in good external health, with a handful of individuals across the site appeared in poor health and were exhibiting skin lesions. These were removed during the inspection and humanely culled. No other clinical signs of disease were observed so diagnostic samples were not taken on this occassion.
The fish sampled for VMD was clinically healthy externally and internally and demonstrated a good feed response. Gut was full of food on examination.
Remote inspection completed on 21/03/24. Site visited on 26/03/24. [Original PDF]
