Abstract
Channa punctatus, exposed to sublethal concentration of phenthoate showed a significant decrease of glycogen content under both static and continuous exposure systems. Further, succinate, malate and lactate dehydrogenases in the muscle, gill and liver tissues showed decreased activity. The inhibition of these enzyme systems was relatively more in continuous flow than in static media. Results indicate that phenthoate reduces the tissue oxidative status of the fish both in static and continuous flow systems. This impact is more conspicuous with the continuous flow system which may be attributed to the continuous availability of the pesticide whereas in the static media pesticide detoxification is possible with progress of time.
