Abstract: A number of pesticides can cause neurotoxicity. Insecticides, which kill insects by targeting their nervous system, have neurotoxic effect in other organisms as well. The present work is regarding the neurotoxic effect of Dicofol, a miticide on fresh water fish Channa punctatus. The neurotoxicity was evaluated on the basis of hematological (Total Erythrocyte Count and Total Leucocyte Count), biochemical (Catalase activity) parameter and behavioural study of the fish and physicochemical parameters of the water after exposure to two different sublethal concentrations of Dicofol i.e., 35 µL and 50 µL in 15L of water in different exposure periods of 3, 5, 10 and 15 days. Alteration in various parameters was observed during different periods of exposure. From the results obtained it is concluded that the pesticide Dicofol induces neurotoxicity in the fish and thus is neurotoxic to other aquatic and terrestrial organisms also.
