| Outline of Final Research Achievements |
In this study, we examined an appearing micro-fauna and an impact to predation pressure by artificial disassembling of Microcystis cell colony. Furthermore, we considered a process of reducing Microcystis in predation pressure of the identified micro-fauna. As a result, protozoan flagellate Monas sp. as a predator of singly disperse cells of Microcystis was estimated by enrichment culture system. In addition, it was confirmed by the combined culture system that the predation pressure of isolated Monas sp. is increased by artificially disassembling colony formed Microcystis to single cells. It was suggested that suppression of Microcystis on small pond was achieved by results of the model experiment which the small scale pond combined with the predation effect of Monas sp. and the system of artificially disassembling Micorcystis cell colony.
