Abstract: 

Electroplating is considered a major polluting industry because it discharges toxic materials and heavy metals through waste water, air emissions and solid wastes in environment. It was found that a large amount of metals and chemicals is disposed into main stream without treatment as they have no effective measures for treatment or recovery of metals in unorganized sectors. The biochemical components like protein, carbohydrate and lipid were estimated quantitatively in the tissues of gill, liver, kidney and muscle of control and electroplating effluent treated fishes. The fishes were treated with the sublethal concentration of 0.13 ml of electroplating effluent for 24, 48, 72, and 96 hours. The protein, carbohydrate and lipid level of gill, liver, kidney and muscle of the control fish was high when compared with the treated ones. In treated fish, the protein content tissues were greatly reduced. Maximum reduction was observed at 96 hrs exposure. The carbohydrate and lipid content of the tissues are showed similar declining trend are different exposure periods.
