A conventional type fish net of webbing material usually of substantial length and having one end which is either closed or closeable, with the other end being open, mountable and attachable to a fishing vessel to which a fish hatch has been added. This fish hatch includes a main flotation body which has a central aperture therein and projecting flanges along the outer circumference thereof for attachment by binding and the like to an opening cut into the side of the fish net. Preferably this is the upper side as the fish net is mounted on the fishing vessel for trolling purposes. A hinged flap is provided on one side of the fish hatch and the hinged flap has openings therein corresponding in size to the webbing of the fish net, that is, of openings which are no larger in size than the apertures of the fish net. This cover closure member is hinged with a built in hinge stop edge for the purpose of keeping the flap opening partly open during a stage of the trolling operations. The fish hatch will normally permit the trash type marine life to escape from the net while retaining the desired shrimp therein.
