Abstract
An experiment was carried out on the effect of levamisole on survival of Siberian sturgeon (Acipenser baeri Brandt) fry. The experiment was done in two series: in first series fish were treated with levamisole 4 days after hatch, and in second series - 11 days. Levamisole was applied in immersion solution, in concentration 5 mg/dm3. Both series of fish were reared until day 27 post hatch. Survival of fish in first series was 77% for fry treated with crystalline levamisole, 69% for fry treated with levamisole in 10% solution, and 47.5% in the control.In second series survival of treated fish was equal to 91%, comparing to 85% in the control.
