There is given the analysis of ecology state of Molochny estuary as one of unique reservoirs of the Azov Sea basin in the modern period. The role of Molochny estuary as natural spawning place for haarder is described. The offers on restoration of fisheries significance of the estuary and on optimum hydrological and hydrobiological mode of it are defined.

Based on the analysis of current biological state of some species of the Kakhovka reservoir, there have been determined indices, which characterized the efficiency of commercial exploita- tion of their stocks. We assessed specific accumulation of crucian carp and pikeperch ichthyomass by age groups. Based on the data of catch distribution by mesh size in fishing gears and age-size structure of crucian carp and pikeperch populations, we proposed measures on optimization of qualitative characteristics of the technical base of fish harvest in the Kakhovka reservoir.

There are presented results of scientific assessment of the situation, which developed on the Kyiv reservoir in the winter of 2010 as well as its consequences. It was found that by investigated indices, the deterioration of the populations state was observed for bream, pikeperch and roach only. For localization of the extreme situation consequences, there are propositions to reduce harvest limits for some species and to restrict fishing zones and gears.

Materials of researches are presented about influence of the use to exterminate in capacities on purging of water of excrescence ponds from pollutant — enhanceable concentrations of organic matters, biogenic elements and heavy metals. Influence of the use is studied to exterminate on development of natural forage base of ponds.

In the article the questions of polyculture efficiency with the use, except for a carp, six types of fishes for market fish growing are represented. It is shown, that polyculture introduction enables additionally to get 507–688 kg of fish from every hectare of fattening ponds, or advance their productivity in 1,4–1,6 times.

The main goal of the experiment was to establish the dependence between fish growth and “life space” volume. The experiment was conducted at the temperature of 23–24 С in five equal series of aquariums (five aquariums of different volume in each group). Body mass and mortal- ity of hatchlings were recorded. “Life space” parameters (volume of aquarium) affect the growth rate of silver carp. Silver carp hatchling needs specific “life space” parameters. Changes of these parameters in any direction lead to stress condition causing growth retardation.

During the spent researches growth rate and percent survival after the season ongrowing between bunches carp younger received with application both native, and defrost cryopreserved sperms have been compared.

The comparative analysis of state of non enzymatic link in the system of antioxidant protec- tion of one and two years old scaled and framed carps’ sera blood of nesvich zonal type have been carried out. In the beginning of vegetation period the contents of retinol in the blood of one year old fish was in track quantity and according to the contents of tocopherol the groups of fish which are under investigation are different between each other have been determined. Have been characterized peculiarities of the activity of non enzymatic link in the system of antioxidant protection in carps’ blood in the processes of ontogenesis.

There presented results of studies of structurally functional parameters of ichthyofauna of the Вerek reservioir (Kharkov region). Dynamics of stocking amounts and catches of aquatic living resources are shown for last four years.
