ABSTRACT:  Agricultural insecticides are used widely to control insect pests .These insecticides enter the aquatic environment through agricultural run off .This study was conducted to assess the histopathological damage of kidney in Clarias batrachus after the exposure to cypermethrin.25 fishes were selected and divided into five groups. Four groups are treated and one is controlled .Treated groups are exposed to sublethal concentration of 0.07 micro litere of cypermethrin for 1,5,10 and15 days respectively .Kidney 0f fish were removed and examined epithelial cells of renal tubule were degenerated ,glomerular capillaries dilated .The result showed that kidney degeneration was proportional to exposure periods and concentration of cypermethrin.
