Layered collection device for drifting roes in shallow water channel

The utility model discloses a stratified collection device for drifting roes in a shallow water river channel. The stratified collection device comprises a combined frame main body, a base and a plurality of combined frame single bodies arranged at the top of the base. The multiple combined frame single bodies are sequentially arranged in the vertical direction, drainage nets are arranged at one ends of the combined frame single bodies, egg collecting boxes are arranged at the other ends of the combined frame single bodies, and connecting rods are arranged between the drainage nets and the egg collecting boxes. The device can be fixed to a shallow water river channel and can be automatically assembled, and long-term stable roe collection at a fixed point is achieved; by arranging the small-caliber roe collecting device for the shallow water river channel, the influence of mature fishes and other impurities on roe collection is reduced, and regular research on roe movement of the shallow water river channel is
