Abstract

Concentration of copper (Cu) and zinc (Zn) in liver and muscle tissues of Kutum (Rutilus frisii kutum) of the Caspian Sea was assessed to study possible correlation of length and weight and the bioaccumulation of these heavy metals in the fish. Concentration of the metals in liver was higher than muscle (Zn: 55.2, Cu: 41.5kg/g) while the concentrations in the muscle tissue were lower than permissible limits proposed by FAO. Significant correlations were not detected between mean Zn and cu concentration and fish size. Finally, no significant difference was found in the concentration of the heavy metals in male and female fish specimens (P>0.05)......
