The biological value of freshwater fish of Kremenchug reservoir

The article analyzes the literature resources and own researches concerning biological value indicators of Kremenchug reservoir freshwater fish. The expediency of using this material to expand the range of biologically valuable food. These fish species are characterized by high reproductive capacity, rapid growth, low feed costs, which makes them valuable perspective objects for cultivation and industrial processing. The results of studies of chemical, fatty acid, amino acid and mineral composition of carp, silver carp and beam meat and values their safety are given. It gives a comparative analysis of nutritional value of carp, bream and silver carp, as one of the perspective industrial processing objects. The differences in the studied parameters of these fish are indicated. The given results of studies of the general chemical composition of these species of freshwater fish indicate that the raw material is high in protein and medium fat, and the protein contains all essential amino acids. The results of analysis of the mass fraction of toxic elements in the investigated species of freshwater fish are presented. It was found that the available heavy metals in the silver carp, carp and beam organs and tissues are less than established limits. It indicates, however, that the freshwater fish species selected for research are food-safe and can be used for further industrial processing.
