Abstract: Alterations in certain enzymes have been examined in the liver and ovary of a fresh water murrel, Channa punctatus (Bloch), after exposure to 10 mg/l (Group II), 15 mg/l (Group III) and 25 mg/l (Group IV) zinc for 8,10 and 15 days. Untreated fish (Group I) served as control. Acid phosphatase (ACP) was inhibited both in the liver and ovary. Alkaline phosphatase (ALP) decreased in the liver while it increased progressively in the ovary. Serum glutamic pyruvic transaminase (SGPT) and serum glutamic oxaloacetic transaminase (SGOT) enzymes showed a significant increase with an increase in dose and duration of the experiment. Secretion of these enzymes indicates significant pathological changes in the liver and ovary. These changes would also have an adverse influence on the functional capacity of these organs.
