Assessment of Food Value of Fishes-Biomeliorators in terms of the Content of Heavy Metals

Yu. V. Pilipenko
Kherson State Agrarian University Kherson, Ukraine

ABSTRACT

Results of the study of the process of accumulation of the ions of heavy metals in the organs and tissues of various species of fishes-biomeliorators occurring in artificial ichthyocenoses of small reservoirs used for various purposes are given in the paper. It has been found that the lowest concentration of toxic substances was observed in fishes occurring in the reservoirs used for drinking and technical water supply, whereas their highest concentration was registered in fishes occurring in the reservoirs receiving the spilled irrigation waters. Fishes occurring in the reservoirs used for irrigation occupied the intermediate place. The content of the ions of heavy metals in the organs and tissues of various species of fishes occurring in small water bodies used for different purposes was lower than their limiting permissible concentration.
