5 Common Fish Diseases And How To Spot And Treat Them

Fish disease and parasites

Like humans and other animals, fish suffer from diseases and parasites. Fish defences against disease are specific and non-specific. Non-specific defences include skin and scales, as well as the mucus layer secreted by the epidermis that traps microorganisms and inhibits their growth. If pathogens breach these defences, fish can develop inflammatory responses that increase the flow of blood to infected areas and deliver white blood cells that attempt to destroy the pathogens. Specific defences are specialised responses to particular pathogens recognised by the fish's body, that is adaptative immune responses. Some commercially important fish diseases are VHS , ich and whirling disease. All fish carry pathogens and parasites.

When fish are living under less than optimal conditions, their resistance to disease is reduced, and they may be infected by common diseases that are often present in the environment at low levels. For this reason, it is very important to make sure that we do all that we can to ensure a good environment for our aquatic animals and protect them from the introduction of exotic diseases.

For commercial aquaculture ponds, tanks, and raceways, the most important environmental considerations are these:.

It may even be worthwhile to ask the supplier about their fish health inspection program.
