The invention discloses an ecological fish way with multi-flow-speed channels. The ecological fish way comprises a fishpond, the low-flow-speed fish passing channel, the medium-flow-speed fish passing channel and the high-flow-speed fish passing channel, wherein the low-flow-speed fish passing channel, the medium-flow-speed fish passing channel and the high-flow-speed fish passing channel are all formed in the fishpond and extend in the direction consistent with the direction of water flow. According to the technical scheme, the ecological fish way can meet the running requirement of various fishes in ecological fish communities of rivers, the fish passing effect of the fish way is improved, and therefore the species of fishes passing through the fish way is increased, and the species diversity and the ecological balance can be maintained.
