Sectional water replenishing type fish collecting channel

The invention discloses a sectional water replenishing type fish collecting channel. The upstream section of a water replenishing channel (1) is provided with a water replenishing pipe (5), a partition wall (3) is located between the water replenishing channel (1) and a fish collecting channel (2), and the water replenishing channel (1) and the fish collecting channel (2) are arranged in parallelwith each other; and the partition wall (3) is provided with a plurality of water replenishing hole groups (6) in a spaced mode, a river side wall (4) is arranged under the fish collecting channel (2), and a plurality of fish inlets (7) are formed in the river side wall (4). According to the sectional water replenishing type fish collecting channel, the shortcoming that distribution of the water replenishing flow is not uniform between water replenishing holes (6.1) and the fish inlets in the prior art is overcome, and the water flow conditions capable of inducing fish to go upstream in each fish inlet and the fish co
