The fi ngerlings of Cyprinus carpio were exposed to the lethal concentration (7.5 g/l) of quinalphos (Emulsi fi ed Concentrate 25 percent) for 1,2,3 and 4 days respectively to study the levels and whole animal oxygen consumption. Exposed fi sh showed a signi fi cant decrease in the whole animal oxygen consumption due to the respiratory distress as a consequence of the impairment of oxidative metabolism. The ionic content of Na + , K + and Ca 2+ also decreased signi fi cantly in gill, liver and muscle tissue of exposed fi sh, signifying the altered cellular proliferation and deranged Na + , K + and Ca 2+ ionic pump due to probable consequence of tissue damage.
