Abstract : Among the various toxic pollutants, heavy metals are particularly severe in their action due to tendency of bio-magnification in the food chain. The global heavy metal pollution of water is a major environmental problem. With the advent of agricultural and industrial revolution, most of the water sources are becoming contaminated. Natural waters are often contaminated by untreated wastes of industrial, technological and agricultural origin containing various metallic compounds. Heavy metals due to their bio-accumulative and non biodegradable properties constitute a core group of aquatic pollutants. The direct or indirect bioaccumulation of metals in organisms in contaminated water is of great significance because it affects the food chain. In present investigation, the effect of copper sulphate on freshwater fish Clarias batrachus (Linn) has been shown. It was found that the biochemical parameters shown gradual decrease level in tissues exposed by copper sulphate.
