Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is for fishing on the ocean by guiding fish species such as saury, mackerel, and sardines to the surface with a fishing light and sucking them up with a fishing pump. METHODS AND APPARATUS.

(Prior art) As this type of fishing method and fishing gear, a fishing method has been introduced in the industry in which fish are collected using a fishing light and bait, and the suction pump of the fishing pump is opened at the bottom of the fishing light to suck them up. has been done. However, in reality, due to the agility and mobility of the fish, it is not possible to suck up as much as expected, and as the catch is not increasing, it is not usable and is only a theoretical theory.

Fishing pumps are used to capture schools of fish with nets, scoop nets, etc., sandwich the net to deprive the fish of their agility and mobility, and then insert a suction pump into the net to suck up the fish. used in Therefore, even if a fishing pump is actually used, the equipment such as netting or scooping nets for catching schools of fish is extremely exaggerated, and not only does a special fleet have to be assembled, but it is also difficult to use it. Requires many workers to handle
There is a problem that workability is poor.

(Object of the Invention) The present invention was made to solve these problems, and its purpose is to provide a fishing method and device that can catch fish efficiently using a simple device. .

(Structure of the invention) The present invention has been made to achieve the above object,
A net body having a catchment part and a funnel part with an inlet is installed in the sea on the side of the ship, and a fishing pump with a suction port opened in the funnel part is installed on the ship, and the net It is equipped with a large number of fish-collecting lights arranged toward the main body and a guide light arranged on the inlet side of the funnel part, and when the fish-collecting lights are turned on, the school of fish is brought to the surface and directed to the net main body. Then, the fish-collecting light is turned off and the guide light is turned on to guide the fish from the guide port to the pooling part and the funnel part, and the fishing pump sucks up the fish from the suction port. This is a fishing method that uses the fish-collecting light to bring the fish to the surface and guides them to the net body using the guide light, so the fish-collecting efficiency is high even in the wide ocean, and moreover, the fish are not guided into the net body. Schools of fish can be efficiently sucked up by the fishing pump because their agility and mobility are lost in the funnel. or,
A specific configuration for carrying out this method is to open at least one surface of a rectangular frame body of a predetermined size as a guide port, and to stretch a net over the other surface to form a pool,
A funnel part is connected to the side facing the induction port to form a net main body, and the suction port of the suction pipe connected to the fitting pump is opened in the funnel part to improve the mesh structure. The fishing device is characterized in that a plurality of floats and a depressor are provided on the square frame body in order to achieve this, and the structure of the net body through which the school of fish is guided is formed by a pool part and a funnel part, Since the guiding port is formed in the pool area by opening a part of the net stretched around the circumference, the structure is simple, and the net itself is designed to improve the agility and motility of the fish being guided. By depriving fish of fish, it is easy to suck them up using a fishing pump, and by positioning a boat below the tide of a school of fish and moving with the tide along with the school of fish, it is possible to guide the fish efficiently and increase the catch. .

(Embodiment) Next, the present invention will be explained in more detail with reference to the illustrated embodiment. Reference numeral 1 denotes a net body, and the net body is formed by opening one side of a rectangular frame body 2 of a predetermined size, and , an accumulation part 4 formed by stretching a net 3 on the top and bottom faces, and a funnel part 5 on the side facing the one side face are integrally connected to guide the opening on the one side face. It is configured as a mouth 6. The funnel part 5 has a suction port 7a at one end of the suction pipe 7.
is open, and the other end is connected to a fishing pump 8, which is installed on the ship A.

The square frame body 2 is provided with a plurality of floats 9 to float the net body 1, or is suspended from a support bar 10 protruding from the ship A as shown by the imaginary line, to further improve the net structure. In order to do this, a depressor 11 is provided at the bottom of the net body 1. In addition, a large number of fishing lights 12 are arranged on the boat A toward the net body 1 side, and a guide light 13 is installed relatively close to the water surface on the bow side, that is, on the funnel part 5 side of the net body. It is provided.

(Function) The method of catching fish using the fishing device having the above configuration will be explained with reference to Fig. 2. First, when the main ship or ship A discovers a school of fish B using sonar etc., the net body 1 is placed on the side of ship A. The boat travels while setting the boat (see figure A), stops in the direction of movement of the school of fish B and under the tide of tidal current A, and waits, leaving it to the current (see figure B).
Next, turn on the fish light 12 to make the school of fish B surface and move along with the current. After confirming that the school of fish has been attracted by the fish light and has come to the surface and approached the boat, turn on the complete fish light 12. Turn off the lights and turn on the guide lights at the same time.
When it is turned on, the fish are guided in the direction of the school B guide light 13, sequentially enter the pool part 4 of the net body 1 through the guide port 6, and are further guided to the funnel part 5 (see Figure C). The schools of fish that have entered the pool section 4 and the funnel section 5 lose their agility and mobility, so they are rapidly sucked up by the fishing pump 8 through the suction pipe 7 and landed into the boat. .
Inside the ship, the water and fish that are sucked up are easily separated using nets and gutters, and the seawater is allowed to flow directly into the sea.

(Effect of the invention) As explained above, the fishing method according to the present invention is
Set the net on the side of the ship, turn on the fishing light to bring the school of fish afloat and approach the boat, then turn off the fishing light and at the same time turn on the guide light to lure the school of fish into the main body of the net. Since the suction port of the fishing pump is opened in the funnel part, the school of fish that have lost their agility and mobility in the previous funnel part are sucked one after another by the pump. This has the excellent effect of being able to catch fish efficiently and reliably by riding the current while leaving the net in place without having to raise or lower the net.

Furthermore, the fishing device itself has at least one surface of a rectangular frame body of a predetermined size opened as a guide port, a net stretched over the other surface to form a catchment part, and a side surface facing the guide port. A net body is formed by connecting funnel parts, and the funnel part is opened at the suction port of the suction pipe connected to the fitting pump, and the square frame body is opened in order to improve the mesh formation. Since the net is configured with multiple floats and depressors installed in the net, it is easy to set the net in the sea, and there is no need to form a special fleet or special hoisting equipment.
The net is simple in structure, easy to handle, and requires fewer workers.Once set in the sea, the net is not raised or lowered until a single school of fish is caught, so the net does not dissipate due to surprise. Fishing can be carried out quietly and in good condition, and has an excellent effect in that it can significantly reduce the number of personnel and machinery and equipment.
