Abstract: Adult Channa punctatus were acutely exposed to LC50 of zinc (18.62 mg/l), cadmium (11.8 mg/l) and copper (0.56 mg/l) separately for 96 hr The concentration of metals was found maximum in liver and minimum in muscles. The degree of accumulation among the five tissues differed and it was in the order : gill>liver>kidney>blood>muscle in case of Zn, gills>kidney>blood> liver>muscle in case of Cd and gills>kidney> blood>liver>muscle in case of Cu exposure.

Key words : Copper, Cadmium, Zinc, Accumulation, Channa punctatus, LC50
