Research Abstract	In Hachirou Lake (Akita Prefecture) was designated as Clean Lake Act from the progress of eutrophication and the occurrence of "water bloom" in December 2007, the field examination of hepatotoxins called microcystins from blue-green algae and the molecular biological analysis of blue-green algae were carried out. In the results, it was clarified that the blue-green algae were changed dramatically from Anabaena sp. into Microcystis sp. and the toxic water bloom were chiefly formed by Microcystis sp. in Hachirou Lake.
