The effect of some immunomodulators on the growth rate of sturgeon fry (Acipenseridae)

Abstract

The effect of levamisole, ISC, and chitosan applied per os on the growth rate of sturgeon fry was studied. Levamisole added to the feed caused a 20% increase of fish body mass compared to the control, while ISC treatment - 8%. On the other hand, chitosan affected adversely fish growth, causing 33.5% reduction of body mass compared to the control.
