In the conditions of the Republic of Belarus there were determined technological parameters of breeding of larvae of a Lena sturgeon (Acipenser baeri Brandt) to weighing 2-3 g in the conditions of Belarus. On the basis of conducted research, we have established that environment plays considerable role in growing young Lena sturgeon up to viable stage. Especially important are temperature and oxygen regimes and active reaction of pH medium. Decrease in these indicators can lead to, besides reduction of growth rate and viability, different diseases of fish and mass deaths. For the growing of young Lena sturgeon up to viable stage, we recommend the density of 700 fishes /m2 as an initial normative one in the conditions of the Republic of Belarus.
