Abstract: The fish passage target, overall scheme and the design of fish collection and transportation system were studied and analyzed by taking Wudongde Hydropower Station on Jinsha River as an example. According to the river topographic, dam engineering characteristics, fish resources distribution and fish ecological habits, an overall fish passage scheme of “collecting fish in tailrace water, bionic transportation, and releasing fish in running water” was proposed. The fish attraction scheme was characterized as multi-spot, full depth and large flow, which significantly improved the collection efficiency. Meanwhile, by releasing collected fish at running water river section, the migration, feeding and spawning progress were guaranteed. The research result can provide a new idea for fish passage of high dams.
