Abstract
A study of toxic and immune resistant properties of biologically active preparations such as po-tassium orotate, Selekor and composition ETSOK under the action of toxicants and salinity on the daily sturgeon larvae is made. For experimental evaluation of the sustainability of sturgeon larvae the method of functional loads was used. Solutions of sodium chloride and three toxicants: copper sulfate (с = 10 mg/l); synthetic detergent Sarma (с = 100 mg/l) and phenol (с = 100 mg/l) were tak-en as functional loads. Reliability of distinctions of action of biologically active preparations was established by means of Styudent's t-criterion. Studies were performed in the laboratory of sturgeon fish-breeding factory «Alexander». It was stated that the composition ETSOK is toxic protector of stellate larvae against copper sulphate and phenol. Potassium orotate exhibits a protective effect with respect to copper sulfate. ETSOK and Selekor increase immune resistance of stel-late larvae. The obtained data indicate that the mixture of biologically active preparations ETSOK consisting of several substances with different mechanisms of action, capable of protecting the young sturgeon from the action of toxins in artificial conditions.
