Abstract

PURPOSE:To provide a fishing method so intended that fishing operations are carried out while such animals as to interfere fishing like sea-otters or seals are let to escape without losing fishes. CONSTITUTION:The fishing method is such that, in various kinds of fishing method, animals interfering fishing are driven away in a state of having gathered fishes around the fishing vessel by emitting sound waves in the audio frequency range from the vessel in mechanically lifting fishlines or nets.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing method, in particular, a longline, a purse seine and other fishing methods.

[0002]

2. Description of the Related Art As a method of collecting fish around a fishing boat,
It is practiced to sprinkle food around fishing boats, to install electric lights in wire baskets on or under the water around fishing boats, and to use flavors that fish like.

On the other hand, it is known that fish-obstructing animals such as sea otters and fur seals escape by generating sound waves in a relatively large audible frequency range such as a screw sound of a fishing boat and a burst sound such as a gunshot.

[0004]

Therefore, the present invention does not provide a fishing method in which fish are collected by the conventional method described above, and the sea otters and seals that collect further are sought away in search of these collected fish. And

[0005]

The present invention has been made in order to solve the above-mentioned problems, and its gist is the catching method of squid fishing machines, long lines, purse nets, set nets, etc. There is a fishing method in which non-fish animals such as sea otters and seals are evacuated while the fish are collected around the fishing boat by generating sound waves in the audible frequency range when the boat is pulled up to the fishing boat.

Here, the squid fishing machine refers to a so-called "squid fishing robot" installed in a lot on the berth, and the longline fishing method hangs a fishing line at a predetermined interval from the rope,
This means that the net is pulled up, and the purse sein is a fishing method in which two boats wind the fish while winding the net.Furthermore, the set net is to set the net at a specified place and then pull up the net to collect the fish. Refers to fishing methods.

[0007]

The present invention captures fish while generating sound waves in the audible frequency range from the fishing boat, so that the fish may gather but do not escape, and the sea otter that eats fish and damages the nets Efficient fishing methods can be obtained because seals are driven off.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the fishing method of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a schematic view showing a squid fishing condition of a fishing boat equipped with an automatic squid fishing machine, FIG. 2 (a) is a front view of the squid fishing machine used in FIG. 1, and (b) is (a). FIG.

As the squid fishing machine 1, a commercially available one as shown in FIG. 2 is used, and in the machine body 2, a main switch having a power supply voltage set, an electric motor, a water depth, a drum rotation speed, a depth of a ratchet and a hoisting force. Are set so that the winding drums 3 on both sides are rotationally driven. In order to limit the catch of squid and protect squid, some fishing methods that use nets are prohibited by regulation.Currently, the property that squid gathers in moving objects is used to make fish hooks by shakuri. The method of catching on and catching automatically is used. However, with the gathering of squid, seals and sea otters gathered for this, and as a fisherman, they could not kill it, and the current situation is that they are having trouble catching squid.

In view of this, the present catching method provides a method for catching catching animals such as sea otters without worrying about the catch, while carrying out catching squid. As shown in Fig. 1, a large number of squid fishing machines are installed around the ship to carry out squid fishing. When the line is fried by the machines, a group of obstructed animals such as fur seals and seals come. Then, the bell 4 and the loudspeaker 5, which make a sound due to the shaking of the boat provided in the fishing boat 10, generate a sound having an audible frequency so that the squid fishing is continued and the obstructing animal is kept away from the fish. In addition, if the catching animal does not evacuate due to the sound of the bell 4 or the music from the loudspeaker 5, noroshi or fireworks 6 may be launched.

[0012]

[Effect of the Invention] The catching method of the present invention is such that, even if sounds such as music and bells are gathered around the fish, fish such as sea otters, fur seals, and seals cannot be approached. By using this method, sound waves in the audible frequency range can be generated from the fishing boat, and it is possible to evacuate the obstructing animals with the fish collected around the fishing boat and catch the fish. Even if there are restrictions, fish can be caught sufficiently.

Claims (1)

[Claims] 1. In the method of catching squid fishing machines, long lines, purse seins, set nets, etc., when the machines or nets are pulled up to a fishing boat, sound waves in the audible frequency range are generated from the fishing boat to bring the fish around the fishing boat. A method of catching animals other than fish such as sea otters and seals in the collected state.
