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.

Analysis of paddlefish genetic variability with the use of DNA-markers in pedigree stock, which is reproduced and reared in the fish farm “Gornyi Tikich” of Cherkassy region, has been analyzed. It was found high degree of polymorphism by individual microsatellite loci. The obtained results of DNA-markers indicate about possibilities of their use further for certification, identification, and clarification of origin of paddlefish pedigree groups.

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.

In experimental terms defence of vakcinated in abdominal cavity is in the system “parasite– owner”. The haematological and immunological indexes of carps which did not become ill after an infection but became ill on a sharp flow aeromonoza are studied.
