Ministry of Land, Infrastructure and Transport recommends that the water level difference in pool-and-weir fishway must be in the range between 0.1m and 0.2m without any verification. In this study, the water level difference in a pool-and-weir fishway was changed between 0.05m and 0.425m and migration rates were obtained. It was found that Zacco platypus and Zacco temminckii migrate with swimming under the condition that the water level difference is lower than 0.2m and also that Zacco temminckii only migrates with jumping under the condition that the water level difference is in the range between 0.275m and 0.425m. Migration rates concern with the velocity in the orientation area, because the fishes orient in the favorable velocity area.

Effects of the difference of the pool level and neighboring one on migration rate in pool-and-weir fishway
