摘要

The paper presents preliminary results on growth of juvenile Russian sturgeons in an open intensive system. The experiment was conducted at the farm SC Beluga Farm Grup SRL in Tamadau, the Calarasi county. Stocking biomass was provided trough artificial reproduction of sturgeons captured in the Danube. The experiment lasted about 131 days and 30 fiberglass rearing tanks were used. The initial density was 12.5 kg fish/m~3 per tank and the feed practice was appropriate to the development status of the sturgeons. During the experiment were evaluated the following technological parameters: monthly weight gain, daily weight gain and monthly average weight of biomass culture. Also, the physical and chemical parameters of used water were maintained between the limits of optimum range specific to sturgeon growth.
