Rivers in Gifu Prefecture, there are large number of irrigation facilities (agricultural facilities involved in diverting water from rivers to irrigation channels). These facilities are certain to influence the fishes' ascent and descent. It is becoming an important issue to preserve the fishways and natural environment in rivers. This research involves the actual conditions of the fishes' ascent and problems that may arise while facilities established on the fishways. It is time to promote the prefecture, local government, Land Improvement Projects Association (irrigation association) and the fishing industry to cooperate in efficiently enforce the prefecture's plan to not only preserve fishways but also to further preserve the beauty of Gifu's Rivers.
