Název v původním jazyce

Early development and growth of sterlet (Acipenser ruthenus) in the Czech Republic.

Popis výsledku v původním jazyce

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 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 (w) ranged between 0.33--4.23 mm.d-1 and 0.0018--1.6400 g.d-1, respectively. The specific growth rate (SGR) ranged from 25.65 to 2.73 %.d-1. Growth intensity and length parameters are similar to the Starry sturgeon, lower than those of the Siberian sturgeon and Russian sturgeon and significantly lower than at Beluga sturg
