Summary:We examined the concentrations of the heavy metals Zn, Cu, Cr, Pb, and Cd in the liver, gonads, and muscles of male and female starry flounderPleuronectes stellatus from Nyiskii Bay (off the northeastern coast of Sakhalin) in August 1996. It is shown that the accumulation of the metals was different in the organs and tissues of males and females. The greatest differences were recorded in the gonads. The concentrations of Zn and Cu were greater in the gonads of females, whereas the concentrations of Cd, Pb, and Cr were greater in male gonads. More Cd and Pb accumulated in the liver of females, whereas the concentrations of Zn and Cd were greater in the muscles of males. The results obtained seem to reflect the specific features of physiological processes in specimens of different sexes and the biochemical composition of the tissues of fish organs during the period of foraging and gonad development. The concentrations of metals in the muscles of starry flounder from Nyiskii Bay did not exceed the sanitary standards.
