A remote operated vehicle for selectively harvesting a target species in an aquatic environment is disclosed. The vehicle may include a chassis defining a central channel and being configured to hold a plurality of attachments mounted to the chassis. The plurality of attachments may include at least one thruster configured to propel the vehicle in the aquatic environment, and at least one electronics containment unit configured to store one or more electronic devices for controlling an operation of the vehicle. The vehicle may also include a containment unit connected to the chassis and configured to store the target species during harvesting, and at least one stunning device configured to stun the target species. The vehicle may further include at least one suction device positioned at a rear portion of the chassis and being configured to generate flow in a direction extending through the channel to cause the target species to flow into the containment unit.

The invention relates to an automatic retractable float for use with a crab net including a body which floats in water and an automatic retraction and extension mechanism for automatically extending and retracting line from the body. In use the line is attached to the crab net, the crab net deployed and the body floats when in water towards the surface of the water. The automatic extension and retraction mechanism causes the line to be extended and retracted between the body on the surface of the water and the crab net, substantially keeping the line taut to help prevent tangling. The invention also relates to a method of use.

An example line restraint system comprises a housing, a processor, a motor, a release cam, and a timer. The release cam comprises a stem portion and an arm portion. The stem portion is proximate to the housing and the arm portion may be opposite the stem portion. The stem portion may be rotatably coupled to the motor. The motor may be configured to turn the arm portion of the release cam between an open and closed state. When in the closed state, an overhang of the arm portion at least partially defines a cavity capable of retaining a release line. When in the open state, the release cam opens the cavity to enable release of the release line. The timer may receive instructions from the processor to set a particular time and to trigger the motor to turn the release cam from the closed state to the open state.

A fishing tool floating rope. The module stringing core strings a plurality of floating elements at equal intervals. Each floating element has a main body with two ends connected to a neck portion and terminal portion. The neck portion has a radial cross-sectional size less than that of the main body and terminal portion. A covering woven rope is interlaced to cover the module stringing core. The modular snap fastener has a bendable line and plurality of hollow snap fastening members connected to two ends of the bendable line. Each hollow snap fastening member has a U-shaped gap snap fastening slot configured to fit the neck portion. The floating element and modular snap fastener can be quickly assembled to form a string of the module stringing core serving as a center line of circular knitting machine to produce the fishing tool floating rope.

The location of lost or entangled fishing gear, known as derelict gear, is detected. The motion or change of position of a buoy attached to fishing gear is determined via sensors mounted on the buoy and compared to typical buoy motion. If the buoy has moved beyond a threshold value from its original location, an alert is sent to the fisherman. The available sensor data will be used to determine the likelihood of loss or entanglement. This alert facilitates recovery of lost or entangled gear by identifying where immediate retrieval efforts should be focused. The number of traps lost to the ocean that otherwise would continue to trap or entangle marine life may be reduced.
