Abstract

It is important to make clear the fish habitat quality of seasonal changes around river structures in rivers, because this information is useful to make an improvement river plan considering the fish environment. In this study, field surveys of fish habitat quality of seasonal changes by scoring and accumulation around the bridge pier were conducted in Itabitsugawa river which belongs to class B river. River bed of the investigation area including the bridge pier in Itabitsugawa river was flattened by river improvement project in June 2015. It was found that Opsariichthys platypus likes deep area in the river and Canadidia temminckii inhibits the other area .Therefore, the results suggest that riverbed change has an influence for the inhabiting apart of Opsariichthys platypus and Canadidia temminckii.
