Abstract– Over the last few decades the contamination of fresh water with a wide range of pollutants has become a matter of concern. Metal contamination accounts for potential threat for aquatic organisms, which are exposed to significant amounts of heavy metals as a consequence of Industrial, Agricultural and Anthropogenic activities. Heavy metals at high concentration can be hazardous to metabolic, physiological and biochemical system of fish, which in turn affects human beings. The aim of the present study is to investigate the changes in biochemical parameters such as glucose and urea in Channa punctatus. Channa punctatus is commonly known as snake head fish of carnivore feeding habit. The cypermethrin pesticide is widely used in agricultural field for the control of insect pests and is coming under synthetic pyrethroids which have shown strong pesticidal activity in freshwater teleost fish, Channa punctatus.
