Goal of researches - characterization of regularities of radionuclide and heavy metals ac-cumulation by fish in enclosed and semi-enclosed water ecosystem on the territory contaminated as a result of Chernobyl catastrophe as well as development of recommendation for the usage of ponds for: i)fish production; ii)fishing; iii) ranking of ponds according to the level of its ecologi-cal safety. Method of researches - sampling of fish and water, determination of the content of radionuclide and heavy metals, statistical analysis of results. Size trends of 137Cs content into muscles of perch and pike has estimated. Mathematical models described dependences of 137Cs, 90Sr and Lead transfer factors to various species of fish depending on Potassium, Calcium and total mineralization of water has estimated. Methodology of forecast of fish contamination with 137Cs and 90Sr in enclosed and semi-enclosed ponds as well as procedure of the ranking of ponds according to the level of its ecological safety has developed.
