Fipronil is one of the major commercial insecticides in agricultural fields and it is playing an important role on non-target organisms especially to fishes. On exposure to toxicant stress, the physiological functioning of an organism gets disturbed. Hence, the present work evaluated the effect of the fipronil on the oxygen consumption of freshwater fish Catla catla and 96hrs LC50 was determined at 0.6 mg/L. 1/10th of the 96h LC50 was taken as sublethal (0.06mg/l) concentration for oxygen consumption studies and it was carried out for a period of 24 hours, at regular intervals of 2 hours. In the lethal and sublethal concentration the rates of oxygen consumption was increased gradually in the initial time of exposures i.e. 1 to 6hrs after that it was suddenly falls down and the control fish oxygen consumption was also falls down 0hr to 24h. The experimental fish showed various types of swimming movements due to loss of equilibrium.
