Those fish appear to have bacterial-fungal growths. This is a pretty typical occurrance for fish that have gone though stressors of seining, holding, traveling, netting, holding, netting more times, holding again and then final netting sale and transport. It is a wonder as many fish live as they do considering how they are handled and or mishandled. Good reputable fish farms should replace fish that die if you document the occurance with pics and numbers. IMO many small stocked fish are eaten by predators and scavengers before they are completely die, sink or surface.
