Systems and methods for tagging, culling, or tagging and culling fish include various elements. For example, the systems and methods may be implemented on a scale for weighing fish and may maintain a pre-determined color order to suggest a next-up color for a cull tag. In addition, the pre-determined color order may be dynamically updated in real time to account for overrides by an angler or releasing of an already caught fish. In an additional aspect, the scale may have an integrated global positioning system (GPS) sensor to capture position information associated with the catch and used to pull other relevant information.

A gate mechanism (20) is adapted for mounting within the extension (4) of a trawl net (1), the gate mechanism comprising a turbine (47/147/247) for powering rotation of the gate mechanism as it is dragged through the water within the trawl net.

A fishing system includes a submersible fishing implement for being received in a body of water and configured for capturing one or more fish. An implement driver is configured to drive movement of the submersible fishing implement through the body of water. A data collection system includes one or more sensors for sensing one or more fishing parameters and transmitting a fishing parameter signal representative of the one or more fishing parameters. A controller is operatively connected to the data collection system to receive the fishing parameter signal and to determine based on the fishing parameter signal a selected fishing location. The controller is further configured to transmit a navigation signal to the implement driver operative to control the implement driver to drive movement of the submersible fishing implement toward the selected fishing location.

Arrangement and method for manoeuvring a vessel that is towing a load. The vessel has a block at the aft end, over which at least one tow line extends. The block is moveable transverse to the longitudinal axis or longitudinally of the vessel. The position of the moveable block defines a point of attack for a tension force from the tow line. An autopilot is coupled to an actuator moving said block, in order to change the moment of force about a rotation point of the vessel. The autopilot has a calculation unit, which detects the tension force (W1, W2) and calculates the moment of force on the vessel. The autopilot can thus use a change in said moment of force to manoeuvre the vessel.
