摘　　要：The impact of acute exposure of Cypermethrin on the rate of oxygen consumption of the estuarine clam, Katelysia opima was studied. After 12, 24, 36, 48, 60, 72 84 and 96 h of exposure to acute concentration, the average oxygen consumption in LC0 group was 0.215, 0.305, 0364, 0.355, 0.362, 0.376, 0.313, 0.305, 0.297 (ml/L/hr/gm) and in LC50 group it was 0.210, 0.299, 0.356, 0.247, 0.217, 0.244, 0.203, 0.186, 0.174 (ml/L/hr/gm). It was observed that the rate of oxygen consumption fluctuated with an increase in the exposure period. The decrease was maximum in LC50 group as compared to LC0 group.The impact of acute exposure of Cypermethrin on the rate of oxygen consumption of the estuarine clam, Katelysia opima was studied.
