Zusammenfassung:PROBLEM TO BE SOLVED: To provide a fishway where a plurality of fish species having different swimming types and any individuals of different body lengths can go upstream by one kind of fishway, and in particular to provide a fishway where even small-sized fish specifies with weak swimming power and crustaceans such as freshwater prawns and lake prawns that crawl up a bottom surface can go upstream.SOLUTION: By providing a semicircular slope 3 at an angle 90° on a corner part of a pool part of a pool type fishway, respective stages are constituted of three parts that are overflow from a partition wall 1, slope flow, and a part of a pool 4. Thus, various fish species and aquatic organisms can go upstream through one fishway.
