Aquaculture has become the most important part in supplying the source of animal protein, in addition to husbandry for terrestrial animals. For instance, Rohu is a preferred carp variety in most part of the due to its highest market demand whereas Catla is also preferred in the carp farming community owing to its fast growing nature. Diseases are recognized as one of the major constraint to sustainable animal production which can cause significant economic loss especially in aquaculture. Diseases in fish caused by pathogenic bacteria, particularly Aeromonas are most widespread. Septicaemia caused by motile Aeromonads is a ubiquitous problem that affects fishes found in warm, cool and cold fresh water around the world. In the present investigation has aimed to study the efficacy of a Couroupita guianensis fruit extracts antioxidant activity such as catalase and SOD characteristics in an edible fish infected with the bacterium Aeromonas hydrophila. After infection the enzyme concentration will be increased. The post infective Catla fish show decrease the enzyme concentration by the treatment of Couroupita guianensis fruit extract. Conclusion of this present study is Couroupita guianensis fruit extract drastically decrease the Aeromonas hydrophila infection of Catla catla.
