Until 2015 there were no technologies for growing pike perch and works on artificial breeding of pike perch for stocking natural water bodies in Kazakhstan. Cultivation of marketable products in pond farms was also not carried out.
In 2015-2017 in order to develop economically effective technological methods of production of pike-planting pike perch material of the Kazakh Research Institute of Fisheries, studies were carried out on the Development of Economically Efficient Technologies for the Cultivation of Valuable Fish Species and Their Introduction at Fish-Breeding Enterprises in Kazakhstan.
During the implementation of the program works, the methods used in pond and industrial fish farming (in genetic, physiological and ichthyopathological studies) have been applied; In the part of fish farming and fodder production - the relevant regulatory and technical documentation and guidelines.
Technological methods of obtaining pike-planting pike perch material have been developed based on the spawning of pike perch in ponds, obtaining eggs, incubating eggs, obtaining larvae, frying young plants, growing juveniles.
In Almaty region, in 2016, the biotech schemes for growing commercial products (two-year-olds and three-year-olds) of pike-perch in a polyculture with Nylon tilapia`s stockyards, two-year-old carp and white amur were carried out. Survival of two-year-old and three-year-old pike-perch was 100%, the average weight of two-year-olds is 250 g, three-year-olds 750 - 800 g, which corresponds to the requirements of the pike perch commodity condition. As a result of experimental cultivation, satisfactory fish productivity values of 50 kg/hectare were obtained for pike perch in ponds. The fish that make up the polyculture (carp and white amur) during the fish-breeding season reached the marketable weight, an additional yield of fish products was obtained for two years of carp and white amur to 500 kg/hectare.
The results of the conducted researches in the Chilik pond farm showed the real possibility of growing pike-perch`s commercial products in polyculture with carp and white amur in conditions of fish farms in the south of Kazakhstan.
Based on the results of the experimental work, recommendations on the cultivation of commercial pike perch in ponds of fish farms in the south of Kazakhstan have been developed. The patent registration for an innovative way of incubation of fertilized caviar of pike perch has been obtained.
