Abstract: A lobster trap comprising a base panel, two side panels, two end panels, and a top panel defining therein an interior chamber is described. The components of the trap may be primarily or completely made of a plastic material, which increases durability and longevity of the trap. The top panel may have a smaller area than the base panel, and the side panels and/or the end panels are angled inward forming a trap having a substantially trapezoidal prism shape or a pyramidal frustum shape. The trap is shaped and configured to facilitate vertical stacking, and preferably to allow stacked traps to engage with and interlock with each other. The base panel of the trap may have a support member located along the base panel. The support member is at least partially hollow defining an internal compartment, and the compartment is able to receive weight elements that help to stabilize the trap during and after deployment into the ocean.
