As a result of the conducted research, it was established that the yield of local annuals from wintering was on average 86.9% with a range of fluctuations from 76 to 92.7%, while the weight loss was on average 10.2%. Among cross-bred two-year-olds, the two-year-olds obtained from the crossing of a Galician female and a Lyubyn framed male and a Lyubyn female and an Antonina-Zozulenec framed male were characterized by a higher growth rate. The advantage over individuals of the pure line was 21.2 and 28.6%. In general, the average indicator of the individual weight of crossbred two-year-olds is 914.9 g, and exceeds the same indicator of pure lines by 19.9%. At the same time, the average yield rate of crossbred two-year-olds was 88.3% and exceeded the rate of pure lines by 1.65%.
Thus, various crossings were established, which made it possible to obtain highly productive hybrids of the first generation with increased indicators of fish productivity while simultaneously preserving quality indicators of the exterior. The obtained results make it possible to recommend crossing data for the purpose of obtaining new promising lines for industrial cultivation at different levels of intensification in the Polissia zone of Ukraine.
