The article examines the diet of European perch (Perca f luviatilis) of the Kaniv reservoir during spring period. According to obtained data, its ration included 28 food components. The basis of perch diet consisted of fish objects, among which monkey goby (Neogobius fluviatilis) dominated. Among invertebrates found in perch stomachs, leeches were the most significant food item. Despite spawning of the majority of commercial fishes, fish eggs in perch stomachs were in insignificant quantities.

Found that waste of brewing as an alternative of organic fertilizer timulates development of bakterioplankton, an important component of natural forage fish ponds. Proved that the using products of brewing, particularly beer pellet as dressing Fish ponds bakterioplankton intensifyde- velopment of bakterioplankton, and resolve the problem of waste brewing.

The state of macrozoobenthos in cooling basins of Zmievskaya power-and-heating plant and І-ІІ-stage Kurskaya nuclear power plant under impact of cage fich farms has been considered. Data were obtumeimed on augmentation of the “soft” zoobenthos biomasses in areas unimpaeted by the fish cages and its sharp reduction under the cage.

There are presented generalized data on some aspects of pond acuaculture development in Ukraine. The pond fish farming was formed in Ukraine during several centuries and survived both prosperity stages and decline stages depending on the complex of political and social-economical factors as well as peculiarities and dynamics of development of other areas of agrarian production. In the last 50 years, the domestic aquaculture underwent a number of significant changes caused by processes of scientific and technical progress and drastic changes in the enterprise manage- ment system and nature of economical relationships in the country. Last years, there was arisen a necessity for revealing reserves of fish industry development, in particular, a search of new economical economically justified approaches of fisheries activities. Priority tasks of aquaculture are decrease of expenditure of technologies, resource saving, quality improvement and provision of competitiveness of production with concurrent increase of production effectiveness in condi- tions of environmentally safe management.

The data values of allele and genotype frequencies for the loci malate dehydrogenase, malic enzyme and carbonic anhydrase in sires of “Donrybkombinat”, of “Sumyrybhosp” and of “Velykyj Lubin” are given. It is established that the genetic structure of populations of common carp stud- ied by genetic-biochemical systems closes to Hardy-Weinberg equilibrium. It is revealed that the actual heterozygosity tended to increase in relation to theoretically expected heterozygosity in the studied loci. We came to the conclusion that the assessment of polymorphism of these genetic- biochemical systems can help control objective genetic structure of investigated populations of a sazan in the future.
