The present invention is a hoop net comprised of netting mounted to two semicircular tubular rods, forming a ring that maintains its shape and structural integrity. The two semicircular tubular rods are fashioned to connect seamlessly by a fastening means that allows the entire assembly to function as intended. The hoop net assembly includes four stabilizing cords positioned equidistant from each other along the ring, which cords converge at the center of the hoop net assembly and are connected to each other by a fastening means, then further connected to a single draw cord. The draw cord is used to cast the assembled hoop net into water to a desired depth and pulled back into the boat with live bait. Once the hoop net assembly has been used, the metal rods are easily disconnected to facilitate folding the hoop net in half for easy storage and portability.

A steel structure cage for marine crustacean aquaculture and integration thereof into a vertical fish-crustacean aquaculture system are disclosed. The steel structure cage includes a steel frame, top, side and bottom net systems, a ballast tank system, and steel grooves. The steel frame includes internal and external steel frames. The steel grooves are fixed on upper and lower ends of the internal steel frame. Edges of the top and bottom net systems are respectively fixed into the corresponding steel grooves. The side net is welded on the internal steel frame. The ballast tank system is arranged between the internal and external steel frames. A HDPE cage is moored to the steel structure cage to form a vertical aquaculture system. Whereby, an ideal culturing environment for marine crustaceans is given and the objective of vertical aquaculture culturing fish at top water layers and culturing prawns (crabs or cowries) at bottom water layers can be fulfilled.

A crab pot including a top, a bottom, and at least one side wall disposed between the top and the bottom, the top, bottom, and the at least one side wall being supported by a frame and enclosing an interior space. The crab pot further includes at least one entrance tunnel in the at least one side wall to permit entry of an animal into the interior space, the at least one entrance tunnel including a first end adjacent the at least one side wall and a second end opposite the first end, the second end disposed within the interior space. The crab pot also includes a trigger including at least one rod pivotably mounted at the second end of the at least one entrance tunnel.

A hand-held underwater net assembly with a snare closure that easily and rapidly closes the netting to prevent fish and crustaceans from escaping. The net assembly ideally includes a brightly colored net closure cord which serves to draw the netting together and close the netting when the snare handle and telescopic draw stem are proximally pulled outward and retracted by a user. The extension of the handle of the net assembly, pulls the netting into a closed position. The brightly colored net closure cord makes it easy for the underwater user to determine when the net is in the closed position and the catch is securely contained within the netting.

A lobster trap stabilization system having one or more hinged fins, each fin enclosed in a containment structure located in a lobster trap opposite the weighted side of the trap, whereby the fins provide increased drag to a trap descending to the ocean floor while the trap is in an improper orientation relative to the ocean floor, thus facilitating trap rotation to achieve proper trap orientation, and provide little to no drag to a descending trap while it is in its proper orientation.
