Histopathological changes in Kidney of Channa punctatus (Bloch) under stress of Folidol

The concentration of pesticides is increasing day by day in the aquatic ecosystem. These concentrations are highest to limits; there is bioconcentration and bioaccumulation of these pesticides in the tissues and organ of fish which has a harmful effect on the human being when consumed by them. The effects of Folidol at 20 ppm sublethal doses were investigated on histopathology of kidney in full grown specimen of Channa punctatus (Bloch). Significant alterations were observed in kidney sections of treated fishes as compared to control group. These changes may be due to damage caused to the hepatic tissue.
