摘要：

The paper is presenting aspects regarding the influence of feeding level on the breeding of Siberian sturgeon in a recirculating aquaculture system (RAS). The experiment took place over 30 days, in 4 pilot breeding units of type aquariums of 300 l in volume. Two kinds of feeding level variants were compared, with two repetitions: V1 with 5.5 g/kg metabolic weight (1.2% from total biomass) and V2 with 11 g/kg metabolic weight (2.4% from total biomass). The same stocking density of 20 fish/unit and the same pellets with 46% crude protein were used. The parameters of fish breeding showed that changing the quantity of fodder, the fish growing was positively influenced. This experiment showed that Acipenser baerii is a sturgeon with a rapid growth rate and it is possible to obtain an increase of fish biomass using different quantity of pellets with 46% crude protein.
