DETERMINATION OF OPTIMAL PLANTING DENSITY OF STURGEON (ACIPENSER RUTHENUS) JUVENILES IN THE FORMATION OF BREEDING STOCK

Abstract

One of the most difficult elements in the technology of sturgeon cultivation at the Dnieper hatchery is the formation and further maintenance of sturgeon repair broodstock. In the article the data of own special researches of influence of density of landing of fry sterlet on the basic fish-economic indicators are resulted. As a result of the conducted research and analysis of their results, it was determined that with increasing sterlet stocking density the body weight growth rate decreases, the survival rates of the grown fry and the overall fish productivity deteriorate. The optimum of stocking density in the cultivation of sterlet planting stock, which will be used later for the formation of a repair broodstock, should be counted as 75,000 specimen/ha. The average weight of the obtained fry of this variant ranged within 2.59 ± 0.25 2.68 ± 0.30 g and averaged 2.63 ± 0.27 g, with an average growth from cultivation of 67,59%.
