Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a fishing ground creation system that creates a new fishing ground in any sea area, and in particular, transmits data such as fishing schools, sea conditions, weather, etc. from the fishing ground to a base station wirelessly. The base station processes and stores the data and provides appropriate instructions.

[Conventional technology]

More than 99% of Japan's current fish production occurs in coastal areas (approximately 9.9%) and upwelling areas (approximately 0.1%), which occupy only approximately 10% of the total sea surface, and most sea areas are underutilized. It is in.

For this reason, even if we try to increase the amount of fish caught, we are constrained by various factors such as international relations, the amount of resources, and costs, and we are in a situation where we cannot do anything we want.

[Problem that the invention seeks to solve]

A system is needed to increase the production of marine resources by developing new fishing grounds in areas where there are currently no fishing grounds, as well as redeveloping existing fishing grounds, and to conduct economical fishing.

What I would like to focus on here is the production volume of the entire coastal area,
It is estimated that the production of all upwelling areas is approximately the same, and from this, the productivity (per unit area) of upwelling areas is approximately equal to that of coastal areas.
It is 100 times more.

From the above, if upwelling water can be obtained, unused sea areas may become promising fishing grounds, and existing fishing grounds such as coastal areas may also be expected to dramatically increase production.

[Means for solving problems]

a communication control buoy, a plurality of anti-collision buoys, a plurality of power supply buoys that respectively supply power to the communication control buoy and the anti-collision buoy, a plurality of floating fish reefs, and each of the buoys and the floating fish reefs each buoy is made of a boat-type buoyant body, and the floating fish reef creates a shade under the water surface, and the communication control buoy, the communication control buoy, and A pump-type deep water pumping device is attached to each of the collision prevention buoy and the power supply buoy, and the deep water containing nutrients pumped up by the deep water pumping device is distributed to each of the floating fish reefs and sent to the communication control buoy. Data on fish schools, sea conditions, and weather observed by the installed sonar transducer, ocean sensor, and weather sensor are sent wirelessly to the base station, which processes and stores the data and sends the appropriate commands as described above. The anti-collision buoy is attached to a control buoy and installed in a predetermined sea area using a mooring rope attached to the anti-collision buoy to create a fishing ground in the optimal sea area.

Additionally, instead of mooring lines, the anti-collision buoy will be equipped with an automatic navigation device to move the fishing grounds to a designated sea area.

〔Example〕

The fishing ground formation system according to the present invention will be described in detail below according to embodiments.

FIG. 1 shows a configuration diagram of one set of the fishing ground forming system according to the present invention. The number of sets can be increased or decreased depending on the sea area and fishing ground size.

1 is a communication control buoy that transmits information about fish schools, sea conditions, and weather between the fishing ground and the base station on land, and all information collected at the fishing ground is transmitted to the communication control buoy 1.
are collected in. The communication control buoy 1 is equipped with a depth sonar transducer (ultrasonic transmitter/receiver), which will be described later.
It is equipped with navigation equipment, surveillance cameras, sea conditions sensors, and weather sensors, and monitors fish school information, location information, sea surface information from surveillance cameras, sea conditions information, and weather information. In addition, sea sensors are installed at depths of 10 m to a depth of up to 50 m, and information from the sea sensors is also collected according to commands from communication control buoy 1. Note that the water depth etc. of the oceanographic sensor can be changed as necessary.

2 is a collision prevention buoy equipped with a radar reflector and a marker light, which will be described later, to prevent ships and the like from approaching and colliding with this system.

3 is the power supply buoy, mainly communication control buoy 1
to supply power. All these buoys 1, 2, 3
Each is equipped with a solar cell, and power and power information are once collected in the communication control buoy 1, from which the required amount is supplied.

Similarly, all buoys 1, 2, and 3 are equipped with deep water pumping devices, which will be described later, and use pumps to pump up deep water containing nutrients from a depth of 200m to 500m (set depending on the sea area where they are installed) to promote the growth of phytoplankton. Useful.

Furthermore, all the buoys 1, 2, and 3 can be expected to function as floating fish reefs, which will be explained next, and have the role of adjusting the overall buoyancy. In addition, all buoys 1, 2, and 3 are made of sturdy boat-style buoyant bodies, and the bow can be directed in the direction opposite to waves and currents to minimize resistance, so they can be used in harsh conditions such as waves in the open ocean. In addition to being able to withstand the environment, the system can be easily moved to a predetermined sea area with little resistance when the fishing area formation system as a whole is moved by towing or by an automatic ship maneuvering device described below.

A connecting member 5 connects the buoys 1, 2, 3 and the floating fish reef 4 via a chain 12, which will be described later, and is configured to maintain the relative spacing between them.

Therefore, each of the buoys 1, 2, and 3 and the floating fish reef 4 can sway independently while maintaining their relative spacing even when there is a large drop in the sea surface and severe vibrations, without colliding with each other and capsizing. Since the fish reefs connected to and surrounded by the buoys follow the movement of the sea surface, they only sway following the movement of the sea surface, and a stable floating fish reef can be formed as a whole without the mooring lines 6 becoming entangled with each other.

6 is a mooring line, which is attached to each anti-collision buoy 2 and has 4 mooring lines per set of the fishing ground forming system according to the present invention.
and connect them at the four corners of this system.

In the first embodiment of the present invention, as shown in FIG. 1, when fishing, the temporary mooring line 6 is removed if necessary depending on the fishing method, and the mooring line 6 is floated to the extent that it does not sink into the sea. 14, and move this system to the extent that it does not interfere with the mooring line 6 for fishing.

〔Effect of the invention〕

In the present invention, a fishing ground formation system consisting of a communication control buoy, an anti-collision buoy, a power supply buoy, and a floating fish reef is floated in any sea area, and the floating fish reef provides shade and creates a favorable environment for fish growth and habitat. A lifting device pumps up deep water containing nutrients from the sea and distributes it to each floating fish reef, allowing phytoplankton to proliferate and fish schools to be collected efficiently.

Even in the open ocean with strong waves and currents, each buoy is made of a boat-type buoyant body, so it has sufficient strength.In addition, each buoy and floating fish reef are connected by connecting members that can swing independently while maintaining relative spacing. Since they are connected, it is possible to prevent mutual collision interference or entanglement of the mooring cables.

Fish schools, sea conditions, and weather data are collected by weather sensors, sea conditions sensors, surveillance cameras, and sonar transducers installed on the communication control buoy and sent wirelessly to the base station, and the base station processes this data. Appropriate treatment can be taken.

Further, in the second invention of the present application, since the anti-collision buoy is provided with an automatic navigation device, the fishing ground formation system can be moved to any sea area by itself.

In this way, new fishing grounds can be created in any sea area, and existing fishing grounds can also be redeveloped, which is an excellent effect.
