Cleaner fish stocks attributed as black loss. Have experienced poor performance of cleaner fish - both wrasse and lumpfish on site. Constant low level mortality since inputs with occasional instant losses after input. AGD identified within stocks but uncertain of cause of mortality. Company considers no remaining stock on site although a small number of wrasse were observed.
Several lethargic fish (Atlantic salmon) observed across the site but not in great numbers. 3 fish removed for diagnostic sampling.
4 x slice treatments since input, 4 fw,1 Salmosan + FW - whole site. Hydrolysing one and a half rounds. [Original PDF]
