Abstract
The freshwater fish, Channa striata fingerlings were exposed to 10% and 30% sublethal concentrations of (LC50 for 96h ppm – 0.38 ppm) monocrotophos for a period of 10, 20 and 30 days to study the effect of monocrotophos on the rate of oxygen consumption. The rate of oxygen consumption in control Channa striata were 0.579, 0.584 and 0.582 ml/O2/g/hr at 10,20 and 30 days, respectively. The fish exposed to sub lethal concentrations of monocrotophos shown the oxygen consumption at the rate of 0.518, 0.439, 0.367, 0.448, 0.382 and 0.274 ml/O2/g/hr at 10 and 30% sub lethal concentrations of 10, 20 and 30 days respectively. In this study, the oxygen consumption was gradually decreasing with increasing exposure periods. Maximum decline (-52.92%) over control in the rate of respiration was noticed in 30% sub lethal concentration on 30 days of exposure.
