Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a meandering motion device for forcibly performing a meandering motion on a bait fish attached to a fishing hook provided at the tip of a fishing line used for longline fishing.

[0002]

2. Description of the Related Art Conventionally, live bait, frozen bait fish used by thawing, or simulated bait has been used as bait for longline fishing.

[0003]

[Problems to be Solved by the Invention] Since the above-mentioned live bait is fresh and the movement in the water is more natural than other baits, a high catch rate can be expected, but on the other hand, it is expensive. In addition, it cannot be kept alive for a long time, and it is difficult to catch and secure bait fish at the fishing ground. not being used.

Further, although the above-mentioned simulated bait contributes to cost saving, it cannot be expected to have a high catch rate, and is therefore used only slightly.

On the other hand, the frozen prey fish that are thawed and used are easy to handle, and are low in price as compared with the live bait.
Currently, most of the frozen bait fish are used.

The present invention respects the above-mentioned advantages inherent in frozen bait fish that is thawed and used, and on the assumption that this is used, the catch rate when the bait fish is used is dramatically improved. Drastically shorten the number of operating days, and
Furthermore, the purpose is to reduce the burden on seafarers engaged in longline fishing.

[0007]

In order to achieve the above object, the meandering motion device of a bait fish according to the present invention comprises a pressure receiving plate 1 formed in a concave shape, and a pointed portion 2 integrally formed on the upper end of the pressure receiving plate 1. An angle holding plate 3 is provided on the rear surface of the root of the pointed portion 2, and a burrow 4 is provided on the front surface of the upper end.

[0008]

As shown in FIG. 7, the pointed head 2 in the meandering motion device of the bait fish according to the present invention is attached to the bait fish 7 attached to the hook 6 provided at the tip of the underwater fishing line 5 used in the longline fishing method. The pressure receiving plate 1 is located at a position closer to the blister head 10 than the belly fin 9 of the
Not shown in the drawing in a state in which the angle holding plate 3 provided on the back surface of the root of the pointed portion 2 is brought into contact with the lower surface of the bait fish 7 while being pierced so as to be diagonally positioned below 0. The main rope is hoisted by the hoisting machine equipped on the longline fishing boat.
When the bait fish 7 attached to the fishing hook 6 provided at the tip of the fish moves underwater, water pressure acts on the front surface of the pressure receiving plate 1 to cause the head 1 of the bait fish 7 to move.
0 becomes downward and wins.
Is in a state of being perpendicular or nearly vertical to the direction of thrusting in the water, so that a strong water pressure acts on the front surface of the pressure receiving plate 1 in combination with the fact that the pressure receiving plate 1 is formed in a concave shape. Further, since the pressure receiving plate 1 is formed in a concave shape, the left and right balance of the water pressure acting on the front surface of the pressure receiving plate 1 is easy to collapse, and once it starts to collapse, it suddenly collapses. The meandering operation is performed by continuously changing diagonally to the left or diagonally to the right.

Since the angle holding plate 3 provided on the rear surface of the root of the pointed portion 2 is in contact with the lower surface of the bait fish 7, even if a strong water pressure acts on the front surface of the pressure receiving plate 1, Head 1 of bait fish 7
The angle formed with the lower surface of 0 does not increase, and is reliably maintained at a constant angle.

When water pressure acts on the front surface of the pressure receiving plate 1, the cabbage 4 provided on the front surface of the upper end of the pointed portion 2 pierced by the bait fish 7 bites into the fish meat. The biting force becomes stronger as the water pressure acting on the front surface of the pressure receiving plate 1 increases, so that there is almost no possibility that the pointed head 2 pierced by the bait fish 7 will come off.

[0011]

Embodiments of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a pressure receiving plate formed in a concave shape. For example, when the pressure receiving plate is formed in a substantially circular shape as shown in FIG. 1, only the lower half portion is formed in an arc shape as shown in FIG. In such a case, a polygonal shape may be formed as shown in FIGS. 4, 5, and 6, but the shape is not limited to a particular shape. Reference numeral 2 denotes a pointed portion integrally provided on the upper end of the pressure receiving plate 1, an angle holding plate 3 is provided on the rear surface of the root of the pointed portion 2, and a burr 4 is provided on the front surface of the upper end portion.
It is desirable that the angle holding plate 3 is provided on the rear surface of the root portion of the pointed portion 2 so as to project in a slightly obliquely upward direction as shown in FIG. In addition, the above-mentioned burrs 4 can be placed on any part of the pointed head 2.
There may be a case (not shown in the drawing) other than the above.

In FIG. 7, 5 is a fishing line in water used for longline fishing, 6 is a hook provided at the tip of the fishing line 5, 7 is a thawed fish used for catching large fish such as tuna and marlin. A bait fish (mackerel) is hooked on the hook 6 by piercing the hook 6 near the pectoral fin 8. 9
Is the belly fin of the bait fish 7, and 10 is the head of the bait fish 7.

[0014]

[Effects of the Invention] As described above, according to the present invention, the bait fish attached to the fishing hook provided at the tip of the fishing line used in the longline fishing method can be forced to perform a meandering motion. The degree of appeal to the fish will be extremely strong, and this will dramatically improve the catch rate.

Further, due to the dramatic improvement in the catch rate,
The number of operating days will be significantly shortened, and the burden on the seafarers engaged in longline fishing will be reduced, which will be a great contribution to the industry.
