Analysis of Oxidative Stress Responses in Copper Exposed Catla catla

We studied the effect of copper effect on oxidative stress in the liver, kidney of the fish catlacatla. Environmental stress is one of the major challenges faced by Indian pisciculture industry, which affects the growth, reproduction and physiology of fishes. The understanding of the biochemical aspects of stress related responses in fishes to reduce the detrimental effects caused by those environmental challenges comes into need. The activities of the antioxidant enzymes superoxide dismutase (SOD), catalase (CAT) and glutathione S-transferase (GST) were studied after 10 days of exposure to three concentrations of copper.
