PECULIARITIES OF BIOLOGY OF SILVER PRUSSIAN CARP’S SUPERSPECIES COMPLEX CARASSIUS (SUPERSPECIES AURATUS) (LINNAEUS, 1758) IN SPECIAL COMMODITY FISH FARMS

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.
