Влияние основных технологических параметров и состояния кормовой базы на результативность выращивания мальков – покатников русского осетра (Acipenser gueldenstaedtii Brandt, 1833)

Abstract

The article presents the results of studies cultivation Russian sturgeon fingerlings under the influence the main technologies parameters and the condition of the forage base. Russian sturgeon larvae were stocked at densities of 62,0 and 80,0 thousand ind./ha in earthern ponds. On growing significantly influenced forage base in the experimental ponds. With the highest mean rate 144,25 – 144,32 kg/ha in ponds and stoking density in 62,0 thousand ind./ha we received mean body weight 2,5 – 3,0 g with survival rate 71 – 75%.
