Methods, systems, and apparatus, including computer programs encoded on computer storage media for identification and re-identification of fish. In some implementations, first media representative of aquatic cargo is received. Second media based on the first media is generated, wherein a resolution of the second media is higher than a resolution of the first media. A cropped representation of the second media is generated. The cropped representation is provided to the machine learning model. In response to providing the cropped representation to the machine learning model, an embedding representing the cropped representation is generated using the machine learning model. The embedding is mapped to a high dimensional space. Data identifying the aquatic cargo is provided to a database, wherein the data identifying the aquatic cargo comprises an identifier of the aquatic cargo, the embedding, and a mapped region of the high dimensional space.

A handheld crabtrap for catching crabs includes a shaft having a handle with a lever on a proximal end, a trap head with a lid at a distal end of the shaft, and a linkage within the shaft attached to the lever and the trap head. The handle further includes a crab alert bell attached to a cable that also extends to and into the trap head, where it ends in a clip to which the crabber's bait is attached. The trap head is held open via the linkage and lever until a crab pulls on the bait ringing the bell and alerting a crabber to pull on the lever and close the trap head via a string therebetween.

The present invention relates to a method for inducing artificial hibernation of fish that is capable of transporting the fish in a state of being alive for long hours. According to the present invention, a water temperature is gradually decreased from an initial water temperature to the lowest water temperature, the fish are induced to the artificial hibernation, and they are packed in a waterless state. The packing is carried out in an environment where the lowest water temperature is constantly maintained, and a refrigerant is also packed to constantly maintain a temperature in a packing container, while oxygen is continuously supplied to the live fish induced to the artificial hibernation. The fish are individually packed in the Styrofoam box, and even if an atmospheric pressure in the airport is lowered during transport of the fish, there is no danger of causing respiration of the fish to be hard due to a plastic bag damaged. Through the hibernation inducing method and packing capable of reducing stress of the fish, in addition, the fish can be alive in a waterless environment for 36 hours or more, thereby making possible to globally distribute the live fish.

A system is provided that promotes ram ventilation for aquatic animals stored therein. The system includes a horizontally oriented container that maintains fluid flow in one predominant direction with a first end of the horizontally oriented container receiving a first volume of fluid and a second end expelling a second volume of fluid. The second end is provided at an opposite side of the horizontally oriented container than the first end. A slot is provided that extends along a lengthwise direction of the horizontally oriented container between the first and second ends. The slot is positioned along an upper portion of the horizontally oriented container. For example, if the horizontally oriented container is tube-shaped, the slot is provided at an uppermost point on the circumference of a horizontally oriented tube directly across from a point on the tube that contacts an underlying surface such a transom of the fishing vessel.
