Author(s): Suvarna Rawal, Momin Shakir
Abstract: The fresh water fish, Rasbora daniconius has great economic importance, in terms of nutritive values. The pesticides, Endosulfan (Organochlorine) and Synthetic pyrethroid (Cyhalothrin) from the agricultural runoff causing pollution of water bodies of Bhiwandi city wherein the fishes, the non-target organism get adversely affected. Therefore the efforts were made to study comparatively the effects of both the pesticides on percentage mortality (LC50), behavioral and skin melanophore response (photochromatic effects) of fish Rasbora daniconius. The study shows that the used pesticides bring about various physiological disorders in the fish, the LC50 value is very low furthermore, there is marked behavioral and melanophore anomalies compare to control which proves that the selected pesticides have equal degree of toxicity on the test animal. Thus, the release of these pesticides in and around the water resources should be carefully monitored and controlled.
