Abstract

This article is about breeding of the two-years pikeperch in ponds of carp-breeding farm at south-east Kazakhstan. The hydrochemical regime of experimental ponds during the fish-breeding season is presented.

The fact that the water by water supply is meeting the requirements for the water-basins by the fishery purposes discovered by the researches is shown. The dynamic of temperature of water by experimental ponds during the fish-breeding season is attached as well.

The number of species and the level of development of natural feeding base are given. The variety of species of the organisms by natural feeding base also the values of size and biological mass of phytoplankton, zooplankton and zoobenthos are presented in difference versions. The middle feeding level by phytoplankton, zooplankton and zoobenthos are registered like a result of carrying of fish-breeding works and technology melioration works.

Conditions of breeding the pikeperch are described; values of initial mass and hardness of planting by the objects of polyculture are given. The fundamental biological parameters of breeding the fishes which were the objects of polyculture are presented. The analysis of parameters according to the two-years of pikeperch got in results of this experiment is given. The fact that the level of fish-productivity according to the pikeperch is more in ponds there where the fish-productivity according to the common carp is more and it is less there where the fish-productivity according to the grass carp is more is shown in this article.

The fish-productivity according to the pikeperch got in results the experimental works is near 55 kg/ha. The fact that got value of fish-productivity according to the pikeperch is meeting the database of literature sources.

The conclusions of head points of breeding the good production of pikeperch are given.
