| Research Abstract |
Behavior of swimming sweet fish is investigated. The swimming speed, swimming distance and turning angle is made clear quantitatively. As a result, it was found that the burst speed reaches to 20-30 times of body length. Further, swimming trajectories in fishway were recorded both in plunging and streaming flow. It was found that sweet fish always does not have the tendency swimming toward upstream direction.
