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. For this purpose, the top is provided with floatation.

A crustacean trap, comprising: a plurality of generally planar walls forming the interior of said crustacean trap therebetween; at least one of said walls being defined by a central panel and a continuous closed peripheral frame integrally connected with and extending outwardly from the edge periphery of said central panel; said central panel including an open mesh net material of woven strands with the interstices between said strands being substantially larger than the diameter of the strands; said peripheral frame having an inner layer of material, an outer layer of material, the peripheral edge portion of said panel between said inner and outer layers, and bonding means laminating said layers together with said peRipheral edge portion of said panel therebetween; said peripheral frame comprising four straight portions serially interconnected to form a quadilateral frame having at least two straight portions parallel to each other; said panel being so constructed that its strands are woven in a rectilinear grind diagonally oriented with respect to said straight portions so that two adjacent edge portions will form with the adjacent strands extending therebetween a series of increasing area triangles for rigid interbracing; three further walls as defined with respect to said one wall and forming with said one wall the four sides of the container, with adjacent straight frame portions being of one piece construction with each other; further including top and bottom members forming all of the walls of the crustacean trap with said side walls; the lower straight portion of each of said frames including in one piece, a lower generally vertically extending flange, an intermediate portion extending inwardly from the upper portion of said lower flange, and an upper flange extending generally vertically upwardly from the innermost end of said intermediate portion; said bottom member including a reinforced concrete slab having its edge portion, around its entire periphery, fitting within the area of said lower flange and intermediate portion; an elongated rigid securement member embedded at one end within said slab, extending generally vertically upwardly between and spaced from said side walls, and extending outwardly through said top at its opposite end; and means coupled with said opposite end of said securement member for securing said top tightly against the upper periphery of said sides, said top including a central panel of open mesh net material of woven strands with the interstices between said strands being substantially larger than the diameter of said strands and a closed continuous periphery frame of a downwardly opening U-shape comprising inner and outer layers of fabric having the edge portion of said open mesh net material laminated between said inner and outer layers, and said cover when in its closed position having the upwardly extending flange of said side wall frame within the interior of the downwardly extending U-shape; the remaining portion of the interior of said downwardly opening U-shape being filled with a closed pore synthetic resin rigid from; said top central panel including a lobster entrance means comprising an inwardly converging funnel extending through said open mesh net material. A crustacean trap, comprising: four individual generally planar side walls, a top wall and a bottom wall forming the interior of said crustacean trap therebetween; at least one of said side and top walls having means for permitting entry of grown crustaceans within the crustacean trap and preventing their exit; said bottom wall being separable from said side and top walls; releasable connector means for selectively securing said bottom wall to said side and top walls; said four side walls of said crustacean trap being each sloped inwardly toward the top so that the structure of the four side walls and the top wall may be stacked with identical structures in a nesting relationship with their tops closely adjacent each other; said top and side walls, in the complete trap position, being parallel to each other; said bottom wall being of substantially greater density than said top and side walls.
