Year: 2008
Type: article
Abstract: The Acipenser ruthenus (Linnaeus, 1758), albino variety, in the second summer rearing to Brates sturgeons station from Galati was experimented. A number of 513 one year old sterlet were stocked in three Ewos fibreglass tanks, at an individual mean weight of 40 g and total length of 20 cm, in the first day of June 2007. The experiment had extended on 165 days, until half of November. During experimental tries the fishes were monitoring permanently and the essential parameters of technological water (dissolved oxygen, pH and temperature evolution) were checked and recorded. Feeding was achieved with commercial granular food and the conversion coefficient recorded was 1,3. Final body mean weight of sterlet was 130 g/ex. and the average length of 30 cm; the specific growth rate was 0,55g/day., i.e. 90 g/ex, and the survival percent recorded was 89,08 %.
