However, there is little information on the suitable orifice location for shorten the amount of staying time of fish in a pool. In this study, orifice location in a pooland-weir fishway is changed alternate or one-side. Behaviors of ayu, Plecoglossus altivelis altivelis, were obtained with the aid of two sets of digital video cameras. It was found that when orifice location is oneside, the consecutive migration rate becomes high and the amount of staying time of fish in a pool becomes shorten, as compared with those of alternate orifice., 水工学論文集 第55巻}, pages = {1429--1434}, title = {潜孔の設置位置がアユの遡上特性に及ぼす影響}, volume = {67}, year = {2011}, yomi = {オニツカ, コウキ and アキヤマ, ジュイチロウ} }
