Purpose. To review scientific sources on the use of feed yeast preparations in feeding of sturgeon species (Acipenserinae). Findings. The review of scientific works demonstrated that feed yeast in the feeding of sturgeons have been used as a source of vitamins and complete protein, the nutritional value of which is significantly higher than in the proteins of plant origin and are similar to the proteins of animal origin. In addition, a unit of yeast protein mass is significantly lower than in the feeds of animal origin. Moreover, based on the content of B group vitamins, feed yeast produced from the grain-potato spent wash exceed fish meal and meat-and-bone meal. The article highlights the peculiarities of the technological process of the production of different feed yeast species, amino acid and fatty acid composition of their preparations, basic physical and chemical parameters of their composition. The examples of feed yeast formulas for sturgeon species based on feed yeast preparations are presented. It was shown that sturgeon species, especially on early stages of their ontogenesis, could effectively use the feed yeast nucleotides. Thus, the latters can be an effective substitute of live zooplanktonic organisms. While the production of some feed yeast preparations (paprin, eprin) was stopped in 1990s due to a number of social-economic reasons, the works on the creation of their full analogues was continued later. Currently, the trends of the development of world aquaculture anticipates the return to the use of yeast in fish feeding. Therefore, the interest of the agrarians of Ukraine in yeast lately increased and their use in agricultural sector increased by 2-2.5 times. Practical value. The array of the summarized information will be important for scientists who study the peculiarities of feeding of sturgeon species, because the data about the use of yeast as sources of complete protein in fish feeds is important in a constant search for the most effective components of their ration
