| 内容記述 | To develop a new economic and effective fishway which allows migration of juveniles of the edible catadromous Japanese mitten crab Eriocheir japonica over the dam, devices at the upper terminal edge of an experimental fishway, about 30 cm in width, were studied. Various water injection techniques to dislodge the crabs reaching the edge, the use of a smooth floor to promote slipping, and gradually narrowed edge width of the fishway were examined. The effectiveness was compared by assessing the number of crabs which dropped from the edge for 10 minutes. As a result, 76% of the test crabs were successfully dislodged by the injected water from four nozzles, at incidence of 35°, 20 cm in distance from the nozzle to the landing point, and a water velocity of 2.0 l/min/nozzle. A smooth floor was not effective in enhancing the rate of crabs dislodged. In the reduced edge width, 77-88% of crabs were dislodged from the edge without the injection of water. | |||||
