The paper discusses the ways certain biologically active substances can be used to optimize the process of artificial propagation of the sturgeons. The effect of one shot impregnation of roe eggs in progress with opioidically active synthetic oligopeptides (sedatine and dalargine), on the somatometry of Kaluga and Amur sturgeon prolarvae the hepatocytes' plasticity, and the free radical oxidation in the fertilized roe-eggs has been examined. The results of the experiments show that the experimental young fishes gain both in weight and length while the condition of the liver cells and the free radical oxidation system in the fertilized roe eggs improve. On the whole, the processed juvenile come more easily adjusted to unfavorable environment and are better prepared to be released to the natural environment
