Abstract: A lobster trap having a basic four sided container body, wherein the side walls are each constructed of a central panel having open mesh net material of widely spaced strands, which strands are composed of a plurality of tightly spaced individual strands, with the opposite ends of the individual strands being separated and arranged in a fan shape for lamination between close woven fiberglass cloth forming a quadrilateral framework, with the framework of adjacent walls being of one piece. The side walls further have hand holds in the framework.The bottom of the lobster trap is formed of reinforced concrete having a securement bolt embedded therein that extends upwardly through the top, for clamping the side wall framework between the bottom and top. The top is held to the securement bolt by means of a cross pin that is soluble in water so as to release the top after a predetermined submerged time, for corresponding release of trapped lobsters therein when the trap is lost.
