The embryos hatched when reaching a mean total length of 9.0 mm. The exogenous feeding and the larval period of ontogeny started at DAH 9 (day after hatching) reaching TL of 15-17 mm accompanied by melanin plug exclusion. Towards the end of larval period (DAH 39-43, TL 50-58 mm), the embryonic finfold disappeared and the formation of fin apparatus was nearly completed. During the larval and early juvenile development, daily increments of TL and weight ranged between 0.33 – 4.23 mm.d-1 and 0.0018 - 1.6400 g.d-1, respectively. The specific growth rate ranged from 25.65 to 2.73 %.d-1. Growth intensity and length parameters are similar to the stellate sturgeon and lower than those of the Siberian sturgeon, Russian sturgeon and beluga sturgeon. Sterlet’s Fulton weight condition factor was higher than in the Siberian and stellate sturgeon.
