A system of harvesting sea creatures from a trench holding the sea creatures in seawater, including a trench, an injection well, and a harvesting apparatus that extracts the sea creatures from the trench. The trench includes a gate at one end of the trench. The gate insertable into an opening at the end of the trench to prevent seawater from entering or exiting the trench and removable from the opening to allow the seawater to enter or exit the trench. The injection well is positioned external to the trench and can receive the seawater discharged from the trench. The harvesting apparatus includes a conveyor that inclines. The conveyor includes a conveyor belt and a wedge at one end of the conveyor that contacts the bottom floor of the trench when the conveyor is inclined.

A lug track system for crawfish boats approximately 8 feet wide and 14-feet long for the use of guiding a boat along a shallow water track system thereby replacing a steel lug wheel on an existing crawfish boat.

The invention relates to a fishing system (102), a fish processing line (18, 22) and/or vessel (2) provided therewith, and a method (26) therefor. The fishing system (102) according to the invention comprises a fishing net (6) for catching shrimps or fish; transfer means (14, 15, 16) connected operatively to the fishing net (6) for bringing on board the caught shrimps or fish; an automatic detection device (18) configured to detect, classify and if desired sort the shrimps or fish brought on board; a registration system (104) connected operatively to the detection device (18) and configured to receive, store and read and/or transmit data (108) obtained with the detection device (18) about the shrimps or fish brought on board, wherein the data (108) comprise information about the quantity, classification and location of the caught shrimps or fish.

A spring-loaded crabbing device for catching crabs. The spring-loaded crabbing device includes an elongated shaft utilized as a handle, wherein two gripping jaws are connected to an end thereon. The gripping jaws being hingedly connected via a spring biased toward a closed position. The closed position is formed when the outer perimeters of the gripping jaws align with each other, while an open position is formed when the perimeter edges opposite the hinged connection are separated from each other. The gripping jaws are held in an open configuration via a triggering mechanism having two rigid members that are each pivotally attached to a separate gripping jaw and movable radially relative to the gripping jaws. The rigid members of the triggering mechanism interact in a way which allows the gripping jaws to move into the closed position when activated.

A harvesting unit with one or more pumps including one or more suction nozzles directed towards the seabed, one or more inlets that lead from the suction nozzle to the pump, an outlet to a sorting device, one or more motors for driving the one or more pumps, where the sorting device, which at least separates bottom-dwelling marine organisms from bycatch and foreign bodies, has an outlet for bottom-dwelling marine organisms leading to a collecting unit, a structural main frame that carries at least the harvesting unit, and a towing and launching system for deployment and propulsion of the harvesting unit.

The sand rake of the present invention includes: a filter body, having an open filtering space and a plurality of filtering holes distributed across all sides thereof, a front side of the filter body being formed as an inclined surface and having a top edge with a plurality of teeth, while a bottom side of the filter body being formed as a flat surface; a support component, disposed in the filtering space of the filter body; and a handle, disposed at a rear side of the filter body. Accordingly, by using the specially-structured filter body of the sand rake, it replaces the user's hand in collecting shellfish organisms, increasing the harvest yield and enhancing safety during use.

A gauge for measuring the size of a clam includes a C-shaped body that has a base that extends from a first axial end to a second axial end, a first leg extending from the base proximate the first end and a second leg extending from the base proximate the second end. A gap extends between the first leg and the second leg. The gap having a predetermined magnitude selected to match minimum size limitations for keeping a clam. The gauge being removably securable to a shaft of a clam rake.
