EFFECTS OF TRANSMITTED LIGHT AND BUBBLES IN OPEN-CHANNEL FLOWS ON FISH BEHAVIORS

摘要：

Fish sometimes enters into an intake gate of dams. Some techniques with electricity, transmitted light and air bubbles have been developed to avoid fish from the intake gate. However, a lot of fisheries co-operative associations pointed out that most of such techniques have no effect. In this study, the color types of transmitted light are changed at both sides of a rectangular water tank and swimming area of Zacco platypus are observed. Further, the air bubbles are injected from the channel bottom and trajectories of fish are observed.
