Quantitative composition of microalgae carotenoids, which are used as feed for larvae of the bivalve mollusks, has been investigated. It was stated that carotenoids of the microalgae Isochrysis galbana Parke, Dunaliella viridis Teod., Tetraselmis suecica (Kylin) Butch., and Phaeodactylum tricornutum Bohl. are represented by six fractions: β-carotene, luthein, fucoxantine, diadinoxantin, and xantophylles of the violoxantine row (neoxantine and violoxantine). Total content of carotenoids in the microalgae depends on the phase of the culture growth. The maximal content of all carotenoid fractions was determined in the stationary fractions. Total content of carotenoids in the microalgae depends on the phase of the culture growth.
