A film-pulling fishway relates to fishways, in particular to improvements of stepped fishways. The minimum height of the partition protruding from the bottom surface of the fishway is 1-1.5 meters; a continuous film is passed over the partition, that is, the entire fishway from the upstream fishway entrance to the downstream fishway exit is covered by a film, the two sides of the film are fixed to the upper end surfaces of the two sides of the fishway, the middle part of the film can sink to the bottom surface of the fishway, and the film is fixed at both ends of the partition when it passes over the partition; the partition can move up and down along the chute; the partition moves in the chute, the chute can accommodate the partition sliding down, the depth of the chute is the height of the partition minus the minimum height of the partition protruding from the bottom surface of the fishway, the height of the partition can make the film between the two partitions in a taut state when the partition rises to the top, so that the film presents a slope to pour water and fish into the water body surrounded by the upper partition and the fishway. It provides great help for the migration of small fish. It can save energy.
