Abstract :

Industrial waste discharge into the freshwater bodies is a major threat to the aquatic life. Wet land near DIC of Nalbari district provides a typical example of aquatic pollution due to the discharge of industrial waste. A study was undertaken during 2011-2012 to examine effects of industrial waste on a hardy fish Channa gachua. Industrial waste affects the integument, gill and several organs of this fish species especially liver and develops histopathological alternation. From the present study the changes observed in tissues of different organs of fishes were evident to show the effects of aquatic pollution.
