Fish Diseases And Health Management

Description

Fish health management is a term used in aquaculture to describe management practices which are designed to prevent fish disease. Once fish get sick it can be difficult to salvage them. Successful fish health management begins with prevention of disease rather than treatment. Prevention of fish disease is accomplished through good water quality management, nutrition, and sanitation. Without this foundation it is impossible to prevent outbreaks of opportunistic diseases. The fish is constantly bathed in potential pathogens, including bacteria, fungi, and parasites. Even use of sterilisation technology (i.e., ultraviolet sterilisers, ozonation) does not eliminate all potential pathogens from the environment.
Fish disease is a substantial source of monetary loss to aqua culturists. Production costs are increased by fish disease outbreaks because of the investment lost in dead fish, cost of treatment, and decreased growth during convalescence. Unlike land animals where physical separation of the diseased animal is much easier, fish in captivity also tend to be in larger numbers than found in nature.
