Application of enzymatic hydrolysis of macrophytes in the technology of feed for juvenile sea cucumber was justified. A basic recipe for compound feed based on fermented marine vegetable raw materials has been developed. Biological tests in the department for the reproduction of sea cucumber on the basis of the Pacific branch of the FSBSI VNIRO (TINRO) (Primorsky region, Popova island) confirmed the effectiveness of the use of fermented algae in the composition of feed. The average daily weight gains of sea cucumber individual increases, and the feed ratio decreases in comparison with feeds based on natural marine plants.
