Habitat preferences of benthic macroinvertebrates were studied according to the different substrate composition. Although it was hard to determine the common dwellers in the habitats with cobbles and pebbles, some taxa such as Ephemera orientalis, Davidius lunatus, Tipula KUb, Isonychica japonica and Tabanus amaenus etc. occurred preferably in the habitats with gravel/sand. In all the sampling stations, the numbers of species collected in the habitats with gravel/sand were always remarkably smaller as compared with the habitats with cobbles and pebbles.
