A shelter for crustaceans adapted to convert to a trap to facilitate harvesting. The shelter is a rectangular structure with a sound- and light-impervious and end walls, and a corrugated metal roof. The side of the structure are constituted by hinged doors pivotable from a horizontal position allowing access to the interior of the shelter to a vertical position closing such access. The movement from open to closed position is effected by cables having one end attached to the door and the other end to a marker float via a main cable.
