organisms and is in bottom of our everyday life activities like cleaning, drinking, washing, agricultural purpose, sea food and
fish food. The harmful effect of any pollutant which entered into water bodies can be assessed by investigating health of
aquatic fauna. In the present investigation, an attempt was made to examine the sub-lethal toxic effect of Chlorpyriphos
(50%) and Cypermethrin (5%) on the histology of liver of Channa punctatus after short term chronic exposure. In the fish
exposed to hybrid pesticides, irregular shape of nuclei, nuclear hypertrophy, necrosis, space formation and vacuolation were
observed in the liver.
