Effects of three biological control agents such as Xanthobacter autotrophycus, Tanichthys albonubes and Oryzias latipes on the morphology and growth of cyanobacterium Microcystis aeruginosa were studied. The experiments were consisted of six treatments of living organism (LO) and culture filtered water of three organisms (CFW). Three LOs effectively decreased the density of M. aeruginosa, and then cyanobacteria hardy showed in the microscopic field after 5 days of cultivation. All LO and CFW agents induced the colonial formation of cyanobacterium M. aeruginosa, although there were little differences in colony formation according to the kinds, density and type of treatment. In particular, the higher density treatment of fish CFW induced effectively the colony formation of cyanobacteria, compared to the bacterial LO and CFW. Thus, the application of bio agents to control the cyanobacterial bloom is needed to the further study to diminish the adverse effects such as the enhancement of colony formation towards on the new bloom against the aquatic ecosystem.
