ABSTRACT:
A device that prevents female and juvenile crabs from becoming stuck in the upper portions of a crab trap is disclosed. In crab traps using angled tunnels, the upper portions of the trap provide a place for the young crab to hide from the larger males. Once in this area, however, the crab are difficult to remove. Many are often killed or injured during removal. To prevent this problem, a formed perforated shield is attached in the wedge-shaped area formed between the inside of the tunnel and the top of a crab trap. Two types of shields are disclosed. The first is an angled shield that conforms to the shape of the upper tunnel and the top of the trap. The shield fits into this wedge-shaped area to provide a smooth surface that makes it impossible for the crabs to find a place to secure a hold. The second device is simply a perforated, flat shield that fits across the space formed by the tunnel and the top of the trap. The shield has contoured ends to conform to the exact space being blocked. Both shields are attached to the crab pot using electrical wire ties placed through holes formed in the shields. Once the trap is returned to the surface, the crab located in the wedge portion (in the case of the first type shield) are simply dumped out, having no place to cling. In the second case, the crab cannot get stuck in the wedge portion and are thus readily removed from the trap. The shields can be made from any saltwater impervious material such as fiberglass plastics, or corrosion resistant or treated metal.
