The results of researching of content and accumulation of trace elements in the fish organs and tissues (heart, muscles, liver, gill and skeleton) are presented in this article. The analysis of heavy and transient metals in the body of fish revealed that in all organs and tissues examined concentrations of iron, and zinc were maximum and those of lead, cadmium and mercury were minimum. High content of metals is typical for more functionally active organs (liver, gill). The paper is said about specific of metals accumulation depending on physical and chemical they capacity, ecological conditions, physiological state and peculiarities of biochemistry.
