抄録: Mass production of the rotifer Brachionus plicatilis is currently conducted mainly by feeding a marine type of Chlorella or a baker's yeast. However, it is still desired to develop the complete substitute for or supplementary diet with Chlorella sp. or the baker's yeast. In Lake Kaiike of Kamikoshiki Island, Kagoshima Prefecture, photosynthetic bacteria (Chromatiacea) is the main primary producer. It supports the production of the first consumers in which the rotifer is usually dominant. In the present study, the sterilized rotifer was cultured in three kinds of the cell suspensions of Thiocapsa roseopersicina collected from Kaiike; the cells without any supplement, a mixture with Chlorella sp. or a baker's yeast and the cells reinforced with some nutrients. The single cells suspension of Thiocapsa roseopersicina had a low nutritive effect on the population growth of the rotifer, and the cells under stationary stage of growth in particular had almost no effect. The mixture with Chlorella sp. or the baker's yeast improved considerably the nutritive quality of the cell suspension of Thiocapsa roseopersicina for the population growth of the rotifer. Even at a very low concentration, the addition of the cells of Chlorella sp. to the cell suspension of Thiocapsa roseopersicina was sufficiently effective in strengthening the nutritive quality. This fact suggests that in supporting the rotifer's growth, Thiocapsa roseopersicina plays dietary role mainly as the reserve of the energy. The addition of vitamin A to the cell suspension of Thiocapsa roseopersicina strengthened the nutritive quality for the growth of the rotifer. This indicates that vitamin A must be one of the essential elements in the nutritive requirement of the rotifer.
