In the present investigation live specimens of Channa punctatus were collected, after acclimatization they were chronically exposed to sublethal concentrations of mercuric chloride for 30 days. As compared to the control fish, Mercury treated fish kidney & liver showed marked histopathological changes. The effect was dose and duration dependents. After 30 days exposure, marked shrinkage of glomerular tuft at all the concentrations were noticed in kidney. Further the effect became so severe that visceral epithelium got ruptured, glomerulus got evacuated and necrosis of kidney tubule was seen. Liver histology showed hepatic congestion and distinct cell boundaries were found to be destroyed. Liver also showed increases in the size of hepatic sinusoids.
