Example Embodiment

[0016] Example 1:

[0017] Such as figure 1 As shown, a pseudo-bait tuna fishing hook includes a fish-shaped hook body 4, one end of the hook body 4 is provided with a hook tip 5, the hook tip 5 is provided with a bait 6, and the hook tip 5 is provided with a barb 16 to improve The stability of the hook tip 5 when it is inserted into the mouth of the tuna. The other end of the hook body 4 is connected to the fishing line 1. The outer wall of the hook body 4 is provided with a fluorescent layer 7. In dark waters, the arrangement of the fluorescent layer 7 and the fish-shaped hook body 4 can visually attract tuna from the tuna, so as to increase the hooking rate of the tuna.

[0018] The fishing hook body 4 is connected to the fishing line 1 through an expansion device. The expansion device includes an air guide housing 15 connected to the fishing hook body 4 and having an air guide cavity 8. The air guide cavity 8 is slidably connected with a piston 3, the piston 3 and the air guid...

Abstract

The invention relates to the field of fish trap instruments, in particular to an artificial-bait tuna fishhook. The artificial-bait tuna fishhook comprises a fish-shaped fishhook body, one end of thefishhook body is provided with a hook point, the hook point is provided with bait, the other end of the fishhook body is connected with a fishing line, and the outer wall of the fishhook body is provided with a fluorescent layer. By adoption of the artificial-bait tuna fishhook, the tuna fishing rate can be increased.

Description

technical field [0001] The invention relates to the field of fish trapping equipment, in particular to a baited tuna hook. Background technique [0002] With the development of my country's ocean-going fishery, the ocean-going tuna longline fishery has become an important pillar of the ocean-going fishery. Deep, generally distributed between 150-350 meters in water depth, there is very little visible light in this area, and the fishing rate of tuna is low. [0003] For example, the Chinese patent announcement number is: CN205455477U, a novel composite artificial bait announced on August 17, 2016, comprising: a first steel wire, a second steel wire, a third steel wire, sequins, a skirt and a fishing hook, wherein, all One end of the first steel wire is provided with a fishing line eye, and the other end is connected to the third steel wire, the first steel wire and the second steel wire are integrally structured, and the third steel wire is provided with two branches, each br...
