The oxygen consumption rate provides a critical index of altering the oxidative metabolic enzymes in freshwater fish Cyprinus carpio. The present study emphasized to understand the increased anaerobic metabolic rates due to lowering the oxygen levels by the acidification of aquatic environment. where the oxidative enzymes like glucose-6- phosphate dehydrogenase (G-6-PDH), lactate dehydrogenase (LDH), glutamate dehydragenase (GDH), succinate dehydrogenase (SDH) and malate dehydrogenase (MDH) in gill and brain of Cyprinus carpio.L exposed at 1 to 7 and 1-15th days of sub lethal concentration of acidic media PH5.0 besides controls, the activities of G-6-PDH, SDH and MDH decreased at day 7th and 15th in the liver and intestine of experimental fishes with a corresponding increased in the activities of LDH and GDH of experimental fish over control. But in between the two organs the degree of decreased activity was observed greater in liver than the intestine of fish. Probably, more destruction of oxidative metabolism occurs in liver than the intestine of fish. Remarkably, in the case of GDH activity was high in liver than the intestine of fish.
