Mercuric chloride induced enzymological changes in kidney and ovary of a teleost fish, Channa punctatus.

The effect of LC(50) (1.8 MG/L) and a sublethal concentration (0.03 mg/L) of in vivo mercuric chloride exposure on the activities of acid and alkaline phosphatases, glucose-6-phosphatase, lipase and urease in the kidneys and ovaries of a teleost fish, Channa punctatus has been studied after 96 hr and 30 days respectively. It has been observed that the activities of all the enzymes except acid phosphatase were significantly inhibited in both the tissues. However, treatment for 96 hr resulted in more marked inhibition than 30 days of treatment. Acid phosphatase showed elevation in activity in the kidney after 96 hr of treatment.
