The results of experimental breeding of one-years of russian sturgeon and his hybrids between the starlet and stellate in reservoirs are adduced in this article. Characteristics of conditions of growing the fingerlings and one-years are given, dependence of middle mass cultivating one-years on analogical parameter of fingerlings is shown. The dynamic of survivation the one-years on different stages of biotechnical process is presented. Peculiarities of experimental rearing the fingerlings and breeding the one-years by russian sturgeon and hybrids “russian sturgeon × sterlet”, “russian sturgeon × stellate” are shown. The fact that lively of fingerlings of russian sturgeon by rearing in reservoirs is depended on starting middle mass of larvae, on thickness of planting the larvae, on timely transfer them to feeding the hand-made food, is established. The fact that lively by fingerlings and one-years of initial parents’ form (the russian sturgeon) was more than by hybrids “russian sturgeon × sterlet” and “russian sturgeon × stellate”, is established too. Also the project of temporary norms of growing the yearlings of russian sturgeon and his hybrids in reservoirs is presented.
