The paper contains results of measures of artificial restoration of native ichthyofauna of the Dnieper reservoirs. It was shown that according to actual indices of fish stocking, one can expect significant recruitment of certain commercial species. The performed estimations of commercial return from yearling Chinese carp stocking indicate on sufficiently high prognostic efficiency of this measure. A procedure of stocking of the Kakhovka reservoir with yearling Chinese carps is proposed. Key words: reservoirs, ichthyofauna, artificial commercial fish propagation, introduction of Chinese carps.

The current state of crucian carp population of the Kakhovka reservoir indicates on high potential opportunities of this species in forming the commercial fishing base. Population and individual indices of crucian carp in interannual aspect are characterized by sufficient stability, the dynamics of the system “recruitment?remain” has positive character. The introduced system of special regimes of harvest will allows significantly increase the efficiency of commercial exploitation of this species in the Kakhovka reservoir. Key words: reservoirs, crucian carp, age structure, commercial fishing.

With an increase in feed hull?less oats in the liver of carp increased content of fatty acids. Particularly in the liver of carp grows in saturated fatty acids with an even number of carbon atoms in the chain and polyunsaturated fatty acids families ω–3 and ω–6. Along with the increasing number hull?less oats in the grain mixes in carp liver increases the intensity changes of linoleic and linolenic acids of total lipids in them more and more long?chain unsaturated derivatives. Key words: carp, liver, fatty acids, lipids, naked oat.

Implementation of deep freeze genital products (cryopreservation) in fish practice the need of continuation of optimizing process of defrosting parameters. The important defines element is the proper matching of the temperature water bath and exposing inside. This research was carried out for the purpose of investigation investigate the effect of different thawing procedures for motility and fertilizing capacity of frozen/thawed grass carp sperm. The studies were conducted during the spawning company in 2012 at the experimental farm "Nyvka" and Institute Fisheries NAAS. The optimal mode of defrostation was conducted among nine variants of the experiment. The conditions of each experiments are determined combination of three temperature water baths: 30, 35 and 40°C and the corresponding exposures of the holding inside it with frozen sperm microtubules of grass carp ? 10, 20 and 30 seconds.The best result for parameters such as total time of motion and percentage of live sperm during thawing and activated sperm were obtained at 35°C and 30 seconds of exposure. Number of live spermatozoa’s reached 77,4±0,57% and time of their movement 75±2,0 seconds. Eggs after ovulation were fertilized by received sperm for the purpose of checking of semen fertilizing capacity. Artificial fertilization was 85,6±2,8% that to confirm fertility received sperm. Key words: cryopreservation, defrosting regime, grass carp, defrosted sperm fertilizing ability, ovulated fish eggs.

We investigated genetic structure of the Ukrainian scaled and framed carps based on six genetic?biochemical systems of blood – TF, ALB, EST, СА, MDH, МЕ. Their level actual and expected heterozygosity per locus has been determined, genetic distances and identity index have been calculated. Differentiation of carp groups of different rearing conditions is possible based on the distribution of allele variants of TF, EST, СА, and ME loci. Key words: carp, alleles, genotype, locus, heterozygosity .

The аrticle is devoted to study linear and weight rates of the silver prussian carp Carassius (superspecies auratus) (Linnaeus, 1758) in small water bodies with equal conditions of existence. Was established the presence of different growth rates of fishes in explored populations which indicates that living conditions of this species isn’t a limiting factor, which defines the rate of growth. It was identified that the populations of the silver prussian carp from the ponds “Avra- menskiy” and “Nina” farm enterprise’s have sufficient measure-weight indexes and undoubted commercial fishery value, but population of the pond “Vodyanikivschina” has no economic value because of low growth rate.

The fisheries and biological parameters of carp by adding to the diet of different varieties of oats are studied. Found that feeding simultaneously both foodmixture 30% an hull-less oats increases the average weight (by 34.6%), the total ponds fish productivity and reduce feed spending. It is shown that the use of oats reduces the intensity of lipid peroxidation.
