EXPERIENCE OF ARTIFICIAL REPRODUCTION OF PIKEPERCH (SANDER LUCIOPERCA) UNDER RAS CONDITIONS

Abstract

Research work was carried out in the research center "Fishery" of the S.Seifullin
Kazakh Agrotechnical University on the artificial cultivation of pikeperch in
recirculating water supply installations in accordance with grant funding from the
Ministry of Education and Science of the Republic of Kazakhstan.
The purpose of our research is to develop technological methods for the
reproduction of European pike-perch (Sander lucioperca) under RAS conditions.
To achieve this goal, the following tasks are defined:
- carrying out fishing of spawners from natural reservoirs;
- obtaining sexual products from producers and subsequent incubation of eggs.
On the basis of the research conducted, incubation modules and installations for
keeping pikeperch spawners were developed and technological processes for
obtaining gametes with subsequent caviar incubation were developed
