Outline of Final Research Achievements |
The migration rate was counted in the fishway with alternated notch under the condition that the slope of bed is positive and also negative in several discharge. The migration rate is higher in the case of slope of bed is positive. The migration rate was counted in the fishway with rough boulders. The migration rate increases with an increase of distance between rough boulders. The effects of turbidity on fish behavior were investigated. It was found that the fish school was splited in turbidity water.
