The drift net is characterized by including a first drift net, a second drift net, a third drift net, a float, a connecting rope, a flow meter and a lead sinker, wherein the second drift net is detachably connected with the first drift net on one side and detachably connected with the third drift net on the other side thereof； the float is fixedly connected with the connecting rope on the underside thereof； the connecting rope is detachably connected with the first drift net, the second drift net and the third drift net on the underside thereof； the lead sinker is detachably connected with the first drift net, the second drift net and the third drift net on the upside thereof； and the connecting rope is fixedly connected with the flow meter. The utility model performs the survey on the fishery resources by using the drift net and the flow meter, which solves the problem that the fishery resources may not be quantitatively calculated by sampling with the drift net. The utility model may provide a netting with different meshes according to sizes of fish for respectively catching fish with specific sizes without catching other fish due to the adoption of a multilayer detachable drift net, thereby preventing the accidental catch and reducing the impact on the fishery resources and the ecological environment.2/2 4 31 2 __22 Figure 2
