THE ANALYSIS OF FISH MOVEMENT BEHAVIOR IN VERTICAL SLOT FISHWAY BASED ON VIDEO TRACKING

The fish movement behavior and hydraulic condition in fishway are suitable, which is the key of designing vertical slot fishway. In this paper, using video tracking method of computer technology obtain fish movement trajectory, swimming acceleration, swimming velocity. Compared to manual tracking analysis method, the method of video tracking can effectively obtain fish movement behavior, which can reduce manual operation and provide important basis data for vertical slot fishway design.
