Early development and growth of sterlet (Acipenser ruthenus) in the Czech Republic
Growth rate of sterlet larvae and juveniles during 2008 and 2009 was studied under experimental and farming conditions of the Czech Republic. 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)...

Growth rate of sterlet larvae and juveniles during 2008 and 2009 was studied under experimental and farming conditions of the Czech Republic. 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.
