The Present study is aimed to asses the histological damage caused to the fish channa punctatus exposed sublethal concentration of synthetic pyrethroid derivative a cypermethrin. The LC5O values were calculated 0.00078 m/lit at 96 hrs exposure period. Light microscopic studies exhibited sever histological the kidney showed reduction in renal cell number in the proximal and distal collecting tubules, which have resulted in narrowness of humen. The kidney demonstrated hyperplasia, vacuolation, degeneration an necrosis leading to the complete necrosis. The lumen of the tubules was found to extended kidney tubules were also found to be perforated. Keywords :- Histlology, channa punctatus , cypermethrin, kidney.
