CULTIVATION AND REPRODUCTION OF THE REPAIR GROUPS OF THE FIRST, SECO

This article presents the results of the creation and replenishment of new generations of domesticated pike-perch (Sander lucioperca) obtained in pond conditions. Rearing two-year-old pike-perch from the second generation at a stocking density of 12 yearlings per hectare allows for an average weight of 250 g and a fish productivity of 2.2 kg/ha. Rearing three-year-old pike-perch from the first generation at a stocking density of 20 two-year-olds per hectare results in an average weight of 511 g and a fish productivity of 9.4 kg/ha. Rearing yearlings of the third generation with continuous rearing at a stocking density of 150 fry per hectare leads to an average weight of 16.8 g. The rearing of yearlings, two-year-olds, and three-year-olds has demonstrated their high productivity and resistance to the conditions of pond farms in the Republic of Moldova. This allows for their use in replenishing new lines and creating new broodstocks of pike-perch from the pond population.
