Study on Upstream Migration of Fish Through A Vertical Slot Fishway
Proceedings of the International Symposium on Fishways '95
The Organizing Committee for International Symposium on Fishways '95 in Gifu
Fishways are located at each end of the dam across the lower part of the Kitakami River which open to the Pacific Coast of northern Honshu, Japan. Each of the single-jet vertical-slot fishways is 60.5m long with 16 slots which were made between baffles. 732 ayu fish and 90 other fish species swam up the two fishways in the two days of June 12 and 20, 1991. 2,458 chum salmon and 55 other fish species swam up the two fishways during the five days from September 12 to October 23, 1991.
