The pesticide pollution different classes like organochlorines, organophosphates, carbamates and other new generation ones affect the fish oxygen consumption in sublethal concentrations. Respiratory responses to lethal concentrations increase the ventilation volume and symptoms of pesticide intoxication suggesting that the effect on respiratory surface were high in fish. Hence, in the present study an attempt has been made to study the effect of lethal(1.2 µg/l) and sub-lethal 1/10(0.12 µg/l) LC50 and 96hrs of 50% mortality concentrations of Ethion 50% EC an Organophosphate effect on oxygen consumption for 24 h at each 2 hours interval to the Indian major carp, Labeo rohita (Hamilton). Oxygen consumption of aquatic animals is a very sensitive physiological process and therefore, alteration in the respiratory activity is considered as an indicator of stress of animals exposed to pesticides. The significant drop in the rate of oxygen consumption was observed in the present study in lethal and sub-lethal concentrations. [ABSTRACT FROM AUTHOR] |
