CATDOLL : CATDOLL: What are the fish diseases?

Some nutritional diseases can cause the death of farmed fish, while some nutritional diseases will not directly cause the death of farmed fish, but due to the reduced disease resistance of fish, they are susceptible to pathogens and may affect their commercial value. For example, albinism, which is a common color loss or mottled, cataracts, short body disease, thinning of back muscles, etc. are all common diseases. The increase in the incidence of fish nutritional diseases warns us that we should pay attention to the quality of aquatic feed.
