Analyzes the main results of the work on the preparation and cultivation of young fishes of Russian sturgeon at Zhitnensky sturgeon hatcheries of Ikryaninsky District of Astrakhan region. When working on the production of juvenile sturgeon have been used by manufacturers of Russian sturgeon winter races and domesticated birds. Found that in the hatchery season 2014 actual values hatchery-biological indicators in most cases correspond to, and sometimes exceed standards: the average weight of females exceeded the norm by more than 3 kg in winter females of sturgeon, and 2 times more than normal - have domesticated; average working fertility exceeded performance standards by 62 thousand pieces have domesticated female of Russian sturgeon, in the winter - to meet regulatory; manufacturers survival of Russian sturgeon at long standing correspond 100%. Actual data on the percentage of wild and domesticated maturation producers after injection were slightly below standard and were 84 and 81%, respectively. Survival rates of eggs is also within the norm and was even slightly higher. Survival rates for juveniles of the Russian sturgeon was 59.4% (standard - 50%). Mass produced fingerlings into the river reached 3.6 g, which exceeds the standard.
