Abstract
Histopathological changes in the gills, liver, kidneys and gonads and heavy metal accumulation have been studied in peled (Coregonus peled) from the Lower Ob basin. It has been shown that there is a relationship between pollutant concentrations in tissues and environment and the degree of pathology in the internal organs and that the morphofunctional status of fish has an effect on their reproductive potential. Impairment of reproductive parameters resulting from the accumulation of cadmium, mercury, and lead in fish tissues has been revealed. The ambiguous effect of pollution on the reproductive potential of the Ob peled population is discussed.
