POSTEMBRYONIC DEVELOPMENT, SURVIVAL AND GROWTH RATE OF SIBERIAN STURGEON (ACIPENSER BAERI BRANDT
ABSTRACT. Studies were carried out on postembryonic development of Siberian sturgeon (Acipenser baeri Brandt) during 27 days after larvae hatching, in the temperature of 17C. Critical periods of postembryonic development were observed, in which larvae mortalities increased. These periods were: begin...

| Summary: | ABSTRACT. Studies were carried out on postembryonic development of Siberian sturgeon (Acipenser baeri Brandt) during 27 days after larvae hatching, in the temperature of 17C. Critical periods of postembryonic development were observed, in which larvae mortalities increased. These periods were: beginning of active respiration by the fish and beginning of active feeding on exogenous food resources. Prelarvae metamorphosis took place during the period of 27 days post hatching, and the fish became like adults. |
