The present invention provides a method for handling the content of a catch from a fishing boat comprising the steps of providing a sorting table having crate handling platforms and installing crates on these platforms. The method also has the step of replacing a full crate with an empty crate and placing the full crates on a crate handling frame which frame can be secured within vertical storage containers.

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.

A vessel for farming of marine organisms includes several tanks with seawater and the marine organisms that shall be farmed, where the tanks include a farming net cage that holds the marine organisms and where the tanks are open to the surrounding seawater.

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 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 drain assembly for a fluid tank having a drain hole therein may include a hollow first member to be coupled with the drain hole, where the hollow first member has at least one opening therein. The drain assembly may further include a hollow second member slidably coupled with the hollow first member and movable along a longitudinal axis of the hollow outer member between first and second positions. The hollow second member may be configured to seal the at least one opening in the hollow first member when in the first position to define an upper spillover level for fluid within the tank, and to unseal the at least one opening in the hollow first member when in the second position to define a lower spillover level for fluid within the tank below the upper spillover level.

Vessel (52) for farming of marine organisms (60), said vessel (52) comprises several tanks (38) with sea water and the marine organisms (60) that shall be farmed, where said tanks (38) comprises a farming net cage (10) that holds the marine organisms (60) and where the tanks (38) are open to the surrounding sea water (62).
