An improved, high catch yield pull-behind net assembly particularly designed for shrimping and fishing operations in shallow coastal grass flats is provided which actually causes aquatic life to move upwardly into the net, is completely harmless to the ecology of the grass flats, and can be unloaded on the go without interrupting the fishing and shrimping. In preferred forms, the net assembly includes an upright, inclined, elongated mouth, a trailing net secured to the mouth, and a vibratory, multiple-bar elongated roller mechanism located adjacent the underside of the net mouth for supporting the overall assembly; the roller mechanism repeatedly strikes the bottom in advance of the net mouth, causing bottom-congregating aquatic life (e.g., shrimp and flounder) to move upwardly and pass into and through the net. The net mouth is also provided with a plurality of spaced, depending, spring steel rods which effectively "comb" the grass as the net is advanced to ensure maximum catches.
