Abstract
The liver, gonads, gills, and muscles of five trophically distant charr morphs from Lake Kronotskoe, as well as silty sediments of the lake, were tested for trace-element contents. Concentrations of Mn, Fe, Ni, Cu, Zn, Rb, Sr, As, and Se were detectable in the fish tissues, while the xenobiotics Hg, Cd, and Pb were not determined. The current data indicate a strong correlation between trace-element content and the ecology of each morph and no relationship to the fish length. In the majority, the Ni, Cu, and Zn levels were strongly dependent on trophic biology. The contents of Rb, Mn, and Se were dependent on the distribution of the charr morphs along the depth gradient and correlated with the accumulation of these elements in the bottom sediments.
