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 in the Czech Republic. The embryos hatched when reaching a mean total length (TL) of 9.0 mm. Larvae were fed by living food, with a gradual transition to dry diet. The exogenous fee...
