Abstract
Fishways have been constructed to facilitate migration of fish past dams, waterfalls and rapids. It is necessary to understand appropriate geometrical shape of the fishway. The most of fishway in Japan is pool-and-weir fishway. In order to get high value of migration rate, it is necessary to set up pool length is larger than width of pool. However there is little information of effects of the form of the pool on migration rate from other than a rectangle. In this study, the form of the pool in a pool-and-weir fishway was changed 3 patterns and the discharge in each form was changed. It was found that the form of pool affects on the migration route.
