Endosulfan is classified as extremely hazardous pesticide (Ganestwade et al. 2012) and usually toxic to non – target organisms like fish. It passes via surface runoff into natural waters, where it is accumulated in different organisms like water, especially fish, thus making it vulnerable to several prominent effects. Any change in the aquatic environment causes altered behavioural responses. The present paper therefore, was undertaken to study the behavioural changes in the teleost Clarias batrachus, caused by sub-acute exposure to the organochloride pesticide endosulfan.
