The application discloses a short-term accurate prediction method for tuna longline fishing center fishing ground and hooking route based on middle layer water temperature and ocean current spatial characteristics, and has the characteristics that the fishing ground position is accurately predicted according to the spatial vortex characteristics of the middle layer water temperature (reference 100m water layer, auxiliary reference 50m water layer) and the ocean current (preferably the ocean current of the 100m water layer, auxiliary reference the ocean current of the 50m water layer), and the hooking route is designed according to the method that the hooking route is maximally 90 degrees with the 100m water layer ocean current. The application can accurately predict the fishing ground position and the hooking route by combining the marine environment and the tuna longline fishing boat operation characteristics, and can improve the catch by 10-20% and improve the production effect.

This utility model discloses a fishing device for fish identification, belonging to the technical field of fishing devices. It includes an L-shaped main board with a fishing mechanism inside. The fishing mechanism includes an electric push rod embedded in the inner left wall of the L-shaped main board. A fishing frame is fixedly installed at the telescopic end of the electric push rod. A fish inlet corresponding to the fishing frame is fixedly installed on the inner rear wall of the L-shaped main board, and a fish storage cage is installed to the right of the fish inlet. Through the fishing mechanism, this utility model can dynamically capture and identify fish using a visual sensor. The electric push rod is controlled by a controller, causing the fishing frame to move to the right, trapping the fish inside. Then, the rightward movement of a push plate pushes the fish through the fish inlet and the fish-blocking plate into the fish storage cage. This process repeats, achieving automatic fishing. The principle is simple while improving the fishing yield.

The utility model relates to the technical field of fishhooks, in particular to a squid hook, which comprises a buoyancy bar in a strip-shaped structure. The light-emitting part is stacked on the outer surface of the buoyancy rod and is used for attracting squids in a night fishing environment; the hook part is arranged at one end part of the buoyancy rod and is used for capturing the attracted squids; and the hook handle is arranged at the other end part of the buoyancy rod and is used for binding and installing a fishing line. The squid hook solves the problems that when a paper or cloth fiber body is adopted as a squid hook main body in the prior art, the self-weight of a bent hook piece and a hook handle is large, a buoyancy device does not exist, and the squid hook cannot float in water, so that squids are difficult to attract for a long time, and the fish obtaining is influenced.
