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
