Industrial effluents contributing to aquatic pollution contain a vast array of toxic substances, which include heavy metals. It leads to alteration in physical, chemical and biochemical properties of water bodies as well as that of environment. Electroplating effluent induces deleterious effects on non-target aquatic organisms resulting in imbalance of an ecosystem. The fishes Cyprinus carpio were treated with the sub lethal concentration of 5% Electroplating effluent for 24, 48, 72 and 96

... . Another group was maintained as control. At the end of each exposure period, fishes were sacrificed and tissues such as liver, gill, muscle and kidney were dissected and removed. Samples were tested for carbohydrate, protein and lipid content in the various tissues of Cyprinus carpio under effluent stress were found to be decreased when compared with control. The use of biochemical approach has been advocated to provide an early warning to potentially damaging changes in stressed organisms. The health of any organism is influenced by the physiological activities taking place in body studies on the toxic effects of electroplating effluent on fish have shown varied responses according to the type of species and dosages.
