Abstract

The invention discloses a long line system with a protection structure and a control method. A long line comprises a main rope and a plurality of branch ropes arranged on the main rope. Each branch rope is provided with a fishing hook. The system comprises a controller exposed out of the upper end of the main rope, a storage device, a displayer and an alarm are included, wherein the storage device, the displayer and the alarm are electrically connected with the controller. The part, above the corresponding fishing hook, of each branch rope is provided with a shell with the lower end provided with an opening, and a cover plate arranged on the lower portion of the shell. Each shell is internally provided with a vertical tension spring and a protection cover which is in a horn shape when being expanded. The upper edge of each protection cover is connected with the corresponding shell, a loading block is arranged on the lower edge of each protection cover, and the upper portion of each protection cover is internally provided with a supporting ring with the diameter gradually increased from top to bottom. The lower end of each tension spring is connected with a baffle arranged on the tension spring and used for supporting the corresponding cover plate. The long line system with the protection structure and the control method have the advantages after fishes are hooked, the hooked fishes can be automatically protected, the hooked fishes are effectively prevented from being eaten by other predators, and the economic benefits are good.

Description

technical field [0001] The invention relates to the technical field of fishing equipment, in particular to a longline fishing system with a protective structure and a control method for protecting hooked fish caught in longline fishing. Background technique [0002] Longline fishing is a fishing operation method with a wide distribution and high quantity and output. Longline fishing usually includes a main rope hundreds of nautical miles long, on which there are several branch ropes, hooks and bait are tied at the end of the branch ropes, and the main rope is laid on the surface and middle of the water area by means of floats and sinkers. Or the bottom layer; control the length and sinking force of the traction rope connected to the buoy, and sink the hook to the required water layer. [0003] Because the longline fishing takes a long time, some fish have to stay in the water for tens of minutes or even 1 or 2 hours after taking the bait. The hooked fish will be eaten by ot...
