A handheld crabtrap for catching crabs includes a shaft having a handle with a lever on a proximal end, a trap head with a lid at a distal end of the shaft, and a linkage within the shaft attached to the lever and the trap head. The handle further includes a crab alert bell attached to a cable that also extends to and into the trap head, where it ends in a clip to which the crabber's bait is attached. The trap head is held open via the linkage and lever until a crab pulls on the bait ringing the bell and alerting a crabber to pull on the lever and close the trap head via a string therebetween.

In accordance with at least one aspect of this disclosure, a crustacean trap can include a cage configured to trap one or more crustaceans, and a propulsion system connected to the cage and configured to provide propulsion to the cage. In certain embodiments, the trap can include a controller configured to control the propulsion system to autonomously pilot the trap.

The present invention is a hoop net comprised of netting mounted to two or more 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 netting apparatus especially useful for underwater use for the capture of crustaceans and other prey is capable of one-handed rapid net mouth closure. The apparatus includes an elongate handle coupled distally with a hoop and a flexible net mounted about the circumference of the hoop opening to form a net bunt. Access into and out of the net bunt is selectively restricted by a unique net closure mechanism associated with the handle, hoop and net. The net closure mechanism includes a pair of elastic bands disposed across the hoop opening with the net disposed between the bands to create the net mouth. A drawing apparatus is adapted to stretch the bands apart from one another from their normally relaxed substantially parallel orientation wherein the net mouth is said to be closed to its open position wherein the bands are held under tension. Releasing tension on the bands is carried out by activating a trigger on the handle causing the bands to rapidly return to their closed position for capture of prey within the net bunt.

A fishing device includes a net disposed in a body of water containing fishes. A plurality of posts, wherein each post further includes a stem, a bottom cross disposed at a lower portion of the stem; a cross bar disposed at a top end of the stem; and a cord. The stem is an upright elongated protrusion extending from under a bottom to above a surface of the body of water. The cord is slidably secured to the cross bar. A first end of the cord is secured to a weight. A second end of the cord is secured to the net. The fishing device includes a release mechanism. The release mechanism grabs a portion of the cord to hold the weight in a first position adjacent to the cross bar. A bait system is disposed at or adjacent to a center of the net.

Disclosed is a combined structure of a fishing net cage and floating wind turbine foundation. The combined structure includes a wind turbine and a polygonal deep-sea fishing net cage floating body. The polygonal deep-sea fishing net cage floating body comprises an upper polygonal floating body frame, a bottom ring beam, and a middle truss structure, and a connecting column disposed between the upper polygonal floating body frame and the bottom ring beam. A connection structure of the wind turbine set is disposed on the upper polygonal floating body frame. The bottom of the polygonal deep-sea fishing cage floating body is provided with an interface connected with a steel cable of a mooring system. A sub-tank capable of providing ballast by loading water and buoyancy is disposed in the polygonal deep-sea fishing net cage floating body.

A buoyancy element is for constructing a modular buoyancy system for a circularly shaped net cage. The buoyancy element includes a cage side, an opposite straight long side, and coupling sides between the cage side and the straight long side. The cage side is curved, following the periphery of the net cage.
