Studying productivity of bester yearling in reservoirs of different types

Abstract

The article provides a comparative assessment of traditional and developed fish-breeding tanks for keeping bester yearlings. As a result of growing fish in different reservoirs, it’s been found that when using the “ICA-2” and “INTEX” tanks, there is practically no difference. When comparing the use of "ICA-2" and a semi-buried adaptive reservoir, it’s been found that the weight of fish was higher in the second case, when compared with the benchmark, by 1.5%, the average daily gain - by 5.3%, the coefficient of nutrition - by 1, 2%.
