| Abstract: | In 2004, a restoration project was conducted in the Sakusyukotoni River, a tributary of the Shin River, at Hokkaido University. The water environment and fish assemblage were investigated after the project in 2007. Water quality was good, meeting environmental quality standards, but the assemblages were poor. Only four species were present -ninespine stickleback (Pungitius pungitius), stone loach (Noemacheilus barbatulus toni), shima-ukigori (Gymnogobius opperiens) and dojo loach (Misgurnus anguillicaudatus)- in spite of higher diversity in the main stem, Shin River. In the near future, it might be necessary to manage or restore habitats for lotic biota. |
