Enhanced efficiency of keeping larvae of Stellate sturgeon and paddlefish based on their behavioral peculiarities in early ontogenesis
The efficiency of keeping larvae of Stellate sturgeon and paddlefish based on their behavioral peculiarities in early ontogenesis has been enhanced by feeding on the third day after hatching, which corresponds to the 40<sup>th</sup> stage of development for Stellate sturgeon, and the 38<sup>th</sup> one for paddlefish. These stages of development of sturgeon-formes are characterized by a behavioral change - vertical movements of prelarvae («candles») disappear. Feeding in this period enhances the survival rate and the average daily growth of larvae, reduces the coefficient of variation of weight and length.
