In article the basic biological indicators of sabrefish of the Kremenchuk water reservoir are considered: age structure, average length and mass of separate age groups, individual absolute fruitfulness. It is established that the basic biological indicators of this fish species are at high level that specifies in satisfactory conditions of its existence and sufficient security accessible nutriment. Objective preconditions for definition sabrefish as the rare or a vanishing species are absent.

There are presented assessment results of 3-years breeders rainbow trout breed “Adlerskaya amber” of hand-reared in industrial conditions of Ukrainian. Determination that the first spaw- ning golden trout were survived their high productive and reproductive parameters of grown in a closed water supple system.

The generalised literary data and results of own researches according to the analysis of genetic structure of the species of carp have been presented. It has been described polymorphism of particular genetically-biochemical systems of blood and separation of allele’s frequencies of loci. It have been submitted data about search of correlation linkes of particular loci with economic-valuable signs of carps and use of them in selection work. Use of genetically-biochemical systems as genetic markers of efficiency are most effective only when selection work in economy are performed long.

Development of new sientific approaches for monitoring of channel catfish populations increases effectiveness of selective work. Effective enough can be exterior profile of their habitus, wich is a visual tool for assessment of the state of genefund stocks of channel catfish in water bodies of Ukraine.

The results of researches of carp larvae feeding by moist scrapings preparation (SP) in composi- tion the starting feedstuffs, and its influencing on efficiency of their ongrowing are resulted. The comparative food value of zooplankton and feedstuffs with addition 10 and 20% SP is presented.

In the article presents the results of research content of nonesterified and anionic forms of fatty acids content in the liver and carp’s growth depending on different amounts of zinc in ration.

There are presented results of studies on the state of hydrochemical regime and heavy metal content in water and tissues of cyprinids during a three-year turnover of intensive rearing. It was found that rational feeding of fish and use of other intensification measures (lime, ammophos, superphosphate, organic meanures) do not contribute to the contamination of ponds but ensures high percentage of fish output and normative average fish weight. It was found that cyprinids do not accumulate heavy metals in muscles until the age of three years under conditions of their rearing during a three-year turnover.

Data of own supervisions by application of specifically device of electro-catch for the purveyance of juvenile of valuable fish types in the natural reservoirs of Poland, for the subsequent growing of market fish and spawners in ponds are expounded.
