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 in to 5 groups, one (group I) is control and 4 (II,III,IV and V group) are treated. Fishes of treated groups were exposed to the sublethal concentration of 0.07 µl of cypermethrin for 1, 5, 10 and 15 days respectively. The kidneys of fishes were removed for histological examination. Lesions in the kidney tissues of fishes exposed to cypermethrin were characterized by degeneration in the epithelial cells of renal tubule, pycnotic nuclei in the hematopoietic tissue, dilation of glomerular capillaries, shrinkage of glomerulus, intracytoplasmatic vacuoles in epithelial cells of renal tubules with hypertrophied cells and dialation of the tubular lumen. The results showed that the degree of distortion of kidney was proportional to the exposure periods and concentration of the cypermethrin.
