Abstract: 

Environmental pollution due to toxic heavy metals in air, soil and water is a major global problem. Heavy metals cannot be degraded or destroyed; hence they are persistent in all parts of the environment. The fish, as a bio indicator species, plays an increasingly important role in the monitoring of water pollution because it responds with great sensitivity to changes in the aquatic environment. Fishes were treated with nickel for 24, 48, 72 and 96 hrs in water containing sub lethal concentrations of 2.5ppm respectively. At the end of each exposure period, fishes were sacrificed and tissues such as liver, kidney, muscle and gills were removed and analysed for Protein content. It showed decreased value of protein content in all the tissues when compared to control. Therefore, it is essential to study the toxic effects of Heavy metals on living organisms. The objective of the present work was to observe the effect of nickel on Protein content in gill, liver, kidney and muscle of fresh water fish Catla catla.
