Abstract :

Malathion is the common insecticide [O, O-dimethyl-s-1, 2-di (ethoxycarbamyl) ethyl phosphorodioate] widely used in agriculture on variety of crops of Assam, India. Runoff from treated fields contaminates the nearby bodies of water with organ phosphorus pesticide which are neurotoxic to the ichthyofouna. The present work was designed to study the effect of Malathion on the behavior and histopathology of H. fossilis, as an experimental model fish. The fish were exposed to different concentrations 0.008, 0.025 and 0.050 ppm of pesticides for 72 hours, after exposure, fish exhibited various behavioral changes. Histopathological examination of brain tissues has revealed cytoplasmic and gross histopathological alteration including necrosis and in fractional changes. This result consist with the finding that organophosphate pesticide is neurotoxic in nature.
