  • Patent number: 4956935
    Abstract: A plurality of rigid rods are centrally connected to a hub block and peripherally connected to flexible draw-strings which in turn support a net. The rods are of sufficient length to cause the hub block to be located directly above and over the center of the net and are connected to the hub block by means of any suitable type of spring. A bait spike allows placement of any bait, suitable for attracting crabs, into such a position that the bait will be located directly above and in the center of the net. A retrieval line is attached to the hub block so that upward force on the line causes the springs to partially deform which in turn allows the net to slide downward along the draw strings thereby forming a pouch in the net. This pouch allows for entrapment of the crab for retrieval of the crab fisherman.
