| Research Abstract |
The experiments were conducted in pool-and-weir fishway using ayu. The shape of pool and discharge were changed. It was found that the suitable flow depth were within 0.2m to 0.4m for the 70mm ayu. The migration experiments were conducted in the expanded, contracted and normal width toward the downstream. It was found that the expanded width toward downstream fishway is suitable for migration.
