ABSTRACT
Toxic activity of mercury chloride was tested in vivo on fresh water fish Catla catla. Acute toxicity tests were conducted to measure the impact of toxicity on the fishes within a short period at the various concentrations of HgCl2 (0.1, 0.5, 1, 1.5, 2, 2.5 and 3mg/L). The protein and carbohydrate were estimated using Anthrone by standard methods and enzymes such as Na+-K+, Mg2+ and Ca2+ adenoxide triphosphatases were determined caloriemetrically. Depletion of protein was observed at all exposure periods. The biochemical estimation values of carbohydrates in muscle, intestine and brain showed significant values with P
