| Research Abstract |
The field monitoring of freshwater fish migration was conducted in 3 irrigation and drainage systems, Ishikawa, Japan. The monitoring studies revealed that the migration of Pungitius sinensis (Guichenot), Cottus kazika (Jordan and Starks) and Cottus sp. has been interrupted by weirs and drop structures. To solve this problem, laboratory experiment on the migration of Pungitius sinensis was conducted by making several hydraulic models of fishway. The experiment revealed that the pool-and-weir fishway with orifices provide the highest performance for fish migration in the range of 10-25 L/s. The performance was also verified in the field experiment.
