Fungal Diseases of Fish: A Review

Now a day, fishes are used for biomedical researches along with use as a food also. Chemical contaminants of marine environments are of momentous concern. Similar to other flora and fauna, fish can also be ill with various types of diseases. Freshwater fishes are an important protein source for people of many countries. Fish farming in various parts of the world has increased many folds in the last decade. Bacterial hemorrhagic septicemia, lernaeasis, saprolegniasis and anoxia are the most frequently occurring fish diseases in pond fishes. Fungal infections are among the most general diseases seen in temperate fish. Water moulds infections cause losses of freshwater fishes and their eggs in both natural and commercial fish farms. Although, infection as a result of microbial contamination does not frequently result in disease but ecological stress may upset the balance between the probable pathogens and their hosts. Prevention is, as always, the best medicine. Most infections can be successfully treated if caught early.
