Abstract

The invention discloses a long-line fishing device and a control method of the long-line fishing device. The long-line fishing device comprises a main rope and a plurality of branch ropes arranged on the main rope, and a fishing hook is arranged on each branch rope. The long-line fishing device further comprises a controller arranged at the upper end of the main rope exposed out of water, a storage electrically connected with the controller, and an alarm; a shell with an open lower end and a covering plate arranged at the lower portion of the shell are arranged on each branch rope located above the corresponding fishing hook; a vertical tension spring, an air bottle and an air bag are arranged inside each shell, and each air bag is shaped like a barrel when unfolded; the upper edge of each air bag is connected with the corresponding shell, and a load-bearing block is arranged at the lower edge of each air bag; the lower end of each tension spring is connected with a baffle which is arranged on the tension spring and used for supporting the corresponding covering plate. The long-line fishing device has the advantages of being capable of automatically protecting hooked fish when the fish is hooked, effectively preventing the hooked fish from being eaten by other predators and being good in economic benefit.

Description

technical field [0001] The invention relates to the technical field of fishing equipment, in particular to a longline fishing device and a control method thereof for providing protection to 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 other fis...
