Effect of methanol on catalase activity in Cirrhinus mrigala

Present study was undertaken to measure catalase activity in Freshwater fish Cirrhinus mrigala. For this purpose the fishes were exposed to sublethal concentrations of Methanol and its effect on Catalase activity was measured in gill, liver, brain and muscle of fish on 30^th day of exposure. Among the tissues, liver exhibited maximum increase in the Catalase activity followed by muscle, brain and gill.
