PROSPECTS FOR THE INTRODUCTION OF LAKE AND COMMERCIAL FISH FARMING IN THE CONDITIONS OF LAKE TOMAI

Abstract

The research is funded by the Ministry of Ecology, Geology and Natural Resources of the Republic of Kazakhstan (Grant No. BR10264236). The article about artificial reproduction of pike perch and the rearing of underyearlings in the industrial conditions of the fish farm of the Republic of Kazakhstan. The data of biotechnical methods of spawning of spawners of zander on spawning nests located in the UZV. The sizes of females and males participating in reproduction are determined. The results of the incubation of eggs are given. The dynamics of abiotic environmental factors and their influence on the reproduction of zander is shown. The results of rearing juveniles of zander and rearing of underyearlings in RAS are presented. The results of growing underyearlings in  UZV  with the use of artificial trout feeds from the «Aller Aqua» company are given. The values ​​of the mass accumulation coefficient and the growth rate at different stages of underyearling rearing were determined. The fundamental possibility of artificial reproduction and rearing of zander fingerlings in the industrial conditions of the fish farm in Kazakhstan is shown.
