Runoffs from treated fields contaminates nearby bodies of water with organochlorine componds, which are neurotoxic to the ichthyofouna. The present work was designed to study the effect of bezenehexachloride on the behaviour and histopathology of Heteropneustes fossilis, as an experimental model.The experimental fish were exposed to different concentraions of the pesticide for 72 hoare. After exposure, the fish exhibited various behavioural changes. Histopathological exndnation of brain tis-sue revealed cytopathic and gross histopaholopcal alteratios, including necrosis and infrationalchanges. These results are consistent with the finding that organochlorides cause neurotoxic effects.展开更多
