Preferably, the meshes of the front sections of the sleeve net and the net body are hexagonal, and the meshes of the middle section and the rear section of the net body are prismatic. The hexagonal meshes have smaller resistance than the prismatic meshes, but are easy to damage, so the hexagonal meshes are only used at the front section of the net body. The front section of the net body can be pulled open by the sleeve net in a matching way, the unfolding speed is very high, and the opening speed of the net opening is not influenced by the hexagonal meshes of the front section on the net.
Preferably, the steel rope and the lead rope are also included; the lower edge of the net opening and the lower edge of the sleeve net are fused to form a net lower edge, and the steel cable and the lead rope are arranged along the net lower edge. The lead rope is used for increasing the weight of the lower edge of the net, and the lower edge of the net is prevented from being pushed up by water flow, so that the opening of the net mouth is reduced.
Preferably, the cutting slope of the front section of the sleeve net is 1-1, and the cutting slope of the middle section and the rear section of the sleeve net is 3-1.
By adopting the technical scheme, the utility model has the beneficial effects that: the two sleeve nets of the utility model can drive the net mouth at the front end of the net body to open when the fishing net is dragged, thereby improving the unfolding speed of the net body, further improving the efficiency, increasing the net dropping times and improving the fish harvest. And the net body is divided into three sections, and the length change of the net sheets is matched with the change of the mesh sizes, so that the resistance of the net body when being dragged can be reduced.
