IMPACT OF NICKEL AND ZINC ON PROTEIN PROFILE OF THE SILVER CARP, HYPOPHTHALMICHTHYS MOLITRIXS. ATHIKESAVAN, S. VINCENT, B. VELMURUGAN AND S. JANARTHANANAbstract The effect of nickel chloride and zinc sulphate was investigated in the present study on the protein profile of various tissues like gill, liver, intestine and kidney in the freshwater fish, Hypophthalmichthys molitrix. Fishes were treated with these heavy metals for 30 days in water containing sublethal concentration of nickel (5.7 mg/L) and zinc (6.8 mg /L). Changes in protein profile of nickel and zinc treated fish tissues were observed over control. Many fractions in the Ni treated fish intestine tissues were decreased compared to control value. In nickel treated fish, protein fractions were increased more in the gill, liver and kidney samples when compared to zinc treated fishes.
