A high-precision control system and method for shipborne cryogenic flash freezing of an aquatic product using liquid nitrogen is described. The system may include a main control system, a display unit, a liquid nitrogen supply system, a valve control unit, an acquisition unit, and a power unit. A flash freezing process is divided into four stages: a precooling stage, a flash freezing stage, a deep freezing stage, and a thermal insulation stage. Different cooling rates and flash freezing times are used for different stages, where a cooling rate is used in the flash freezing stage is the highest, a cooling rate used in the deep freezing stage is next, a cooling rate used in the precooling stage is the lowest, and an ambient temperature in a device is kept stable in the thermal insulation stage.

A submersible (10) and method of using a submersible for capturing a target species comprising: at least one controllable thruster (14) for manoeuvring the submersible; at least one camera (12) for capturing images to allow the identification of an individual of a target species; a catapult mechanism (33) wherein the catapult mechanism is reversibly moveable between a released configuration and a primed configuration by an activatable motor, and wherein the catapult mechanism may be loaded with a retractable device mounted on the catapult mechanism, and the retractable device may be launched from the submersible by being propelled by the catapult mechanism; a container for receiving a captured individual.

A tackle storage and organization system for a boat, such as a bass boat, is disclosed. A set of supports is installed in a deck compartment of the boat. The supports may be rails installed specifically for the tackle storage and organization system, or they may be the upper edges of existing partitions for subcompartments within the deck compartment. A box or tray is installed on the supports so as to be slideable horizontally along the supports, but is also removable from the supports. The box or tray may be subdivided into any number of compartments, and in some cases, the dividers used may be removable and repositionable in order to adapt to different types of items. The box or tray may have engaging structure to mount a number of accessories, including a spool accessory.

The present invention provides a catamaran centralized-transportation fishing ship and a control method, which relate to the technical field of fishing of fishing ships. The catamaran centralized-transportation fishing ship has the fishing assembly and the concave chamber for centralized transportation of fish bodies, which can simultaneously have two functions of fishing and centralized transportation, and has a wide application range. Compared with existing fishing ships for fishing operations, the fishing ship can place the caught fish bodies in the concave chamber, so that the fish bodies can be in original water quality during a transfer process, and thus a survival rate of the fish bodies is increased. Meanwhile, setting of the limiting mechanism can prevent the fish bodies from escaping and increase a fishing amount of a single fishing operation.

The present invention relates to an apparatus and a system for managing and securing cargo tubs in stacks in a cargo hold of a vessel, such as a fishing vessel. The functional components of the apparatus and system comprise means such as rails or transport lanes, wagons and pushing structures as transport means for securely managing stacks of tubs in the cargo hold both during sailing and off-loading.
