Quinalphos Induced Alterations in the Levels of Ions and Whole Animal Oxygen Consumption of Freshwater Fish, Cyprinus Carpio (Linnaeus, 1758)

Abstract

Sameer Gopal Chebbi and Muniswamy David

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.
