Description

  The present invention relates to a floating and sinking organic reef in which a tubular outer frame is formed vertically above a fiber-reinforced plastic ship, buoyancy imparting means is attached to the outer frame, and individual plant organic matter is inserted into the space inside the outer frame. And organic matter reef aggregates.

For example, in a frame formed in a rod shape using rod-like or cord-like material, forest products including thinned wood and wood chips are stored in a net-like bag, aiming to grow and proliferate organisms that become fish food, Although there is a technique to promote the growth of seaweeds by attaching and growing fish, it is only necessary to put forest products in a net-like bag and put it in a frame that is formed in the shape of a cage installed in the sea.
A means for regenerating forest products such as thinned wood is a method of pulling up a structure for installation in the sea, and enormous costs are required (for example, see Patent Document 1).

  For example, there are aquaculture cages that have an ups and downs function by using an open type buoyant body that adjusts the amount of gas by connecting a pressurized air feeder and a buoyant body, or a closed type buoyancy body. The present invention is different from the present invention in which the used or waste FRP ship is effectively used, and the expanding and contracting cylindrical outer frame is floated and the organic matter is easily regenerated and inserted (see, for example, Patent Document 2).

  In the background art described in Patent Document 1, there is a technique for storing fishery products such as thinned wood in a net-like bag and trying to fix and grow fish. However, organic waste reefs destroyed by the food chain are not discharged. Easy playback method is not considered.

  Therefore, it is an issue to provide unused organic matter such as bamboo, artificial forest thinning, roadside trees and planted waste, scrap wood and waste wood generated in the lumbering process to an oligotrophic ocean in an inexpensive form. .

  In order to solve the above-mentioned problems, the organic fishing reef of the present invention is an organic fishing reef in which a ship using at least a part of a fiber reinforced plastic is used. A predetermined interval is provided above the vertical direction, and the side surface of the cylindrical outer frame is formed by the outer frame forming member, and buoyancy imparting means is added to the ship periphery or the outer frame forming member, or both, to impart buoyancy. The means is a stationary buoyancy part made of a container filled with foamed resin inside, or a steady buoyancy part made of a sealed rigid container, and a space part by supplying and exhausting pressurized air from the water surface to which a supply / exhaust hose is connected. The floating buoyancy part consisting of a container whose volume changes is formed singly or mixedly, the outer frame lower surface is formed by the ship below the cylindrical outer frame side surface, Inside the outer frame A solid plant organic material having a predetermined volume is inserted into the inner space of the outer frame so that the sum of the objects to be filled is larger than the bulk specific gravity 1 and smaller than the maximum buoyancy of the buoyancy imparting means. Thus, an organic fishing reef in which the upper surface of the outer frame is closed with an outer frame forming member is provided.

  The ship peripheral part located in the said water is the expression describing the state by which the organic matter reef is installed in the water.

  The predetermined interval provided above the ship in the vertical direction varies depending on the water depth and tidal current, but is approximately one-fourth to three times the hull length of the ship and is formed above the periphery of the ship including the ship. Is the height of the outer frame.

  The outer frame, which has a height of about one quarter to three times the hull length, can insert a large amount of organic matter at random. Small fish dwellings appear, and a large amount of aquatic organisms that feed on fish breed and fishery resources are secured.

  The outer frame forming member is a net-like elastic member, rope member, pipe, or hose shape that has a gap through which fry and small fish can pass, preventing dispersal of a predetermined volume of plant organic matter inserted into the inner space of the outer frame. The hollow member, the rod-shaped member filled with foamed resin, and at least one of the ships are configured.

  The fact that the outer frame forming member has a gap through which fry and small fish can pass is to provide a place for fry to protect themselves from large fish, and to provide aquatic organisms that decompose organic matter inserted inside as food. It is an effective means for securing permanent fishery resources.

  The steady buoyancy part includes a steady buoyancy part made of a container filled with foamed resin inside and a steady buoyancy part made of a sealed rigid container, and the cylindrical outer frame side surface constituting the organic matter reef is standing upright. This is important for maintaining a constant posture in water.

  The fluctuating buoyancy part is composed of a container to which a supply / exhaust hose is connected and the volume of the space part is changed by supply / exhaust of pressurized air from the surface of the water, and is important as means for floating to regenerate the organic fishing reef.

  Filling the lower surface of the outer frame with a heavy object is important in order to stabilize the posture of the organic reef by balancing the buoyancy and gravity with the ship inevitably positioned below the outer frame.

  The supply / exhaust hose connected to the floating buoyancy member has one end that reaches the surface of the water, and can repeatedly inject and exhaust pressurized air into the variable buoyancy member from the surface of the water to withstand the water pressure at the installation site. It is a hose.

  The solid plant organic matter having the predetermined volume is bamboo or woody organic matter excluding powder and granular substances, and can be easily obtained from a net-like elastic member having a gap through which fry and small fish can pass. It is a plant organic substance with a volume that does not leave.

  In addition, in order to maintain a stable shape of the organic reef, there is an outer frame revolving member added to the side surface of the cylindrical outer frame, and the outer frame revolving member has a fixed shape or a substantially fixed shape that revolves around the outer frame in the horizontal direction. It is composed of at least one of a sealed hard hollow member, or a pipe-like member filled with foamed resin, a hose-like member, a rod-like member, or a rope-like member, and the outer frame surrounding member is Provided is an organic fishing reef that is added to the side of the frame or that constitutes the uppermost part of the side of the outer frame.

  The outer frame orbiting member having a fixed or substantially fixed shape is added to the side surface of the cylindrical outer frame or constitutes the uppermost part of the side surface of the outer frame. This is necessary to maintain a constant posture.

  In addition, in order to float the organic fishing reef in a stable posture, the posture control device is attached to the side surface of the cylindrical outer frame, and the posture control rope member responsible for the posture control is arranged substantially evenly on the left and right sides of the ship periphery. A plurality of the attitude control rope members are routed around the outer frame revolving member at the top of the outer frame side surface through the cylindrical outer frame side surface and are taken out to the outside of the outer frame side surface. Provided is an organic reef provided as a posture control device at the time of ascent when a mobile heavy object is added in a movable state on the outside of the side surface of the frame and the tip is connected to the ship bottom.

The attitude control rope member responsible for the attitude control is a rope responsible for attitude control for levitating the ship to the approximate center of the side surface of the cylindrical outer frame when regenerating the organic matter reef. Since it is necessary to arrange evenly, it was set as plural.
Therefore, the plurality is a multiple of 2 and is usually 2 × 1, 2 × 2, 2 × 3, 2 × 4, 2 × 5.

  The mobile heavy object has a cavity through which the posture control rope member is passed, and the diameter of the cavity is approximately 2 to 10 times the diameter of the rope, and the total weight used for the fishing reef is the buoyancy at the top of the outer frame. It is a heavy object that is within the buoyancy range of the applying means and is equally distributed to each number, and that can be moved to the lowest point in the rope by passing the attitude control rope member through the cavity.

  When the organic reef with the above attitude control device ascends, the space volume of the uppermost variable buoyancy member is increased by injecting pressurized air from the surface of the water, and the ascending is started. Ascend to the surface of the water, and then surface from the top buoyancy member.

The side surface of the cylindrical outer frame contracts as it floats, and the posture control rope member loosened as it contracts is pulled by a movable heavy object outside the outer frame, and the heavy object moves sequentially to the lowest point. .
Since the posture control rope members are arranged substantially equally on the left and right, the movable heavy object has the same weight, so that the uppermost part of the outer frame floats outward, then floats inward from the top, and finally The ship rises to the approximate center.

  In addition, in order to enhance the function of the organic reef being folded and levitated, a predetermined number of the outer frame revolving members are provided on the side surface of the cylindrical outer frame, and the outer frame revolving members of each predetermined step have the steady buoyancy. An outer frame in which a plurality of the floating buoyancy portions are made of substantially the same volume of elastic members that are sealed and have an air supply / exhaust port. Circulating members are formed singly or mixedly, the floating buoyancy parts of each predetermined stage are connected by a supply / exhaust hose, and the variable buoyancy parts between the predetermined stages are also connected by a supply / exhaust hose. In addition, the air supply / exhaust port of the uppermost floating buoyancy part is connected to the air supply / exhaust hose, one of which reaches the surface of the water, and the lowermost floating buoyancy part is provided with an organic exhaust reef. .

  The predetermined number of steps is about 2 to 10 steps, and the side surface of the cylindrical outer frame is in water and strengthens the role of maintaining a stable shape, which is useful for posture control when ascending.

  Fluctuating buoyancy parts evenly distributed to each predetermined stage are connected to each other by a unit of air supply / exhaust hose and supplied from the air supply / exhaust hose reaching the water surface. When the volume increases from above and buoyancy occurs, and the atmospheric pressure that has shifted to the lowest level exceeds the water pressure, the pressure is discharged from the exhaust port at the lowest level, and the atmospheric pressure in the variable buoyancy part is balanced with the water pressure.

  In addition, in order to enhance the function of the organic reef being folded and levitated, a predetermined number of the outer frame revolving members are provided on the side surface of the cylindrical outer frame, and the outer frame revolving members of each predetermined step have the steady buoyancy. The outer part is configured as an outer frame rotating member by itself, or the outer part is provided with a plurality of the variable buoyancy parts made of a rigid or semi-rigid fixed container having an air supply / exhaust opening and distributed substantially evenly. The frame orbiting members are formed singly or mixedly, and the variable buoyancy portions of each predetermined stage are connected by a supply / exhaust hose, a pipe-shaped member, or an extending hose-shaped member, The variable buoyancy part is connected with a supply / exhaust hose or a hose-like member that extends, and the supply / exhaust port of the uppermost variable buoyancy part is connected to the supply / exhaust hose with one side reaching the water surface, The bottom floating buoyancy part is at least one But to provide the organic matter reefs that are open.

The closed rigid or semi-rigid fixed container is a closable fixed container that does not deform below 1.1 atm. The fixed container in the water is always under the influence of water pressure and at the same time pressurized air. Excessive internal pressure may be generated by injecting.
In order to avoid this problem, in the present invention, by opening the lower part of the connected lowermost fixed container, water enters or is discharged from below, so that the fixed container is always in balance with the water pressure.

  In order to install the organic matter reef at a stable position below the surface of the water, the uppermost part of the side surface of the cylindrical outer frame is on the surface of the water and is independent, and is a steady state consisting of a container filled with foamed resin inside. An organic reef is provided which is connected to a buoyancy member, or a steady buoyancy member made of a sealed rigid container, and a traction means.

  In order to install the organic reef in a stable position as a suspended reef, the underwater gravity of the organic reef is set to be slightly heavier than the buoyancy, and it has a buoyancy greater than the difference between its gravity and buoyancy and is independent on the water surface The method of connecting to the steady buoyancy part is the best.

  In order to effectively use the organic matter reef, a plurality of independent buoyancy members that are independent of each other on the water surface are connected and integrated by a rod-like, pipe-like, or plate-like member. Provided is an organic matter reef that is formed as a buoyancy member and in which a plurality of the organic matter reefs are connected to a collective buoyancy member.

  The above-mentioned water surface is a concept including approximately 30 cm below the water surface and approximately 60 cm above the water surface because it is always under the influence of waves. is there.

  It is necessary to fix organic reefs in a certain sea area, and the side surface of the cylindrical outer frame, the lower surface of the outer frame, or the stationary buoyancy member that is on the water surface and independent, or the assembly The buoyancy member is moored by a device installed on the seabed and mooring means, and the mooring means provides an organic reef that can be repeatedly detached and connected.

  In addition, organic fishing reefs connect adjacent reefs with outer frame connecting means to further stabilize the reefs, limit lateral movement, and provide a stable reef group in water.

  The organic reefs are suspended from the surface of the water, installed on the seabed or lake bottom, used as part of a stationary net, combined with a stationary net, or used as part of a fish collection facility Provide organic reef aggregates that are or are integrated with fish collection facilities.

Since the organic reef has an outer frame through which fry fish and small fish can pass freely, a safe residence is secured, and aquatic organisms that eat organic matter are used as food to breed fry and small fish.
Therefore, in order to find the small fish, large fish gather and provide an organic reef aggregate that has become an efficient means of catching large fish and an auxiliary means of a stationary net and a fish collection facility, or has become a part of a stationary net and a fish collection facility .

  By utilizing the present invention, providing bamboo and woody organic matter in the form of individuals to an undernourished ocean, aquatic organisms that decompose organic matter become food for fish, and a sustainable food chain is completed. And dwellings are provided for young fish.

FIG. 4 is a perspective view of an organic fishing reef in which an outer frame revolving member whose outer frame side surface is approximately the same size as a ship's peripheral edge portion is configured by a steady buoyancy member.

As a method for solving the above-mentioned problems, the present invention aims at an inexpensive organic fishing reef by utilizing a used ship or abandoned ship of a fiber reinforced plastic ship, utilizing unused resources.
The number of FRP ships, which are estimated to be 140,000 in addition to the neglected boats, is reaching abandonment every year. However, the excellent product characteristics of light weight, high strength, and high durability are at the time of dismantling. Recycling that is cheap and effective and that does not consume new energy is an issue.

1-4 are the same embodiment, but will first be described with reference to FIG.
Using the hull (length 13m x width 2.5m x depth 1m) from the used fishing boat (10) of a fiber-reinforced plastic ship, the side of the cylindrical outer frame upward from the periphery Is produced.

  The side surface of the cylindrical outer frame has a shape in which the outer peripheral diameter in the horizontal direction is larger toward the upper side as shown in the side view, or the shape in which the outer peripheral diameter in the horizontal direction is larger in the middle part, or the outer peripheral diameter in the horizontal direction is substantially the same as the ship peripheral part. Among the same size or small shape, and the horizontal planar shape is a substantially circular shape, a substantially elliptical shape, a substantially rectangular shape, or a mixed type thereof, in this embodiment, it is a substantially circular shape and the outer periphery in the horizontal direction as it goes upward. An outer frame with a large diameter was adopted.

  JIS standard vinyl chloride pipe VP150 is processed to produce an outer frame orbiting member (37) having a substantially elliptical shape with a long side of 26 m and a short side of 8 m to form the uppermost outer frame orbiting member (36). A predetermined interval (41) 16m was provided between the peripheral edge (12) and the outer peripheral vertical rope member (35) was used to connect to the ship peripheral edge.

At the midpoint of the outer frame vertical rope member (35), an intermediate outer frame revolving member (37) is added using a rope in the horizontal direction to form the entire skeleton, and a synthetic resin net (34) is stretched over the skeleton, Let it be a cylindrical outer frame side surface (31).
As the synthetic resin net stretched around the skeleton, a net having a gap of 7.5 cm × 12 cm made of a rope having a diameter of 6 mm was used.

  Fluctuating buoyancy members (24) are connected to four locations on the periphery of the ship (12), and an outer frame vertical rope (35) extending from the same position, an intermediate outer frame rotating member (37), and an uppermost outer frame rotating member ( 36) The variable buoyancy member (24) is also connected to the point where the crossing points 36) intersect, and all the variable buoyancy members are connected by one unit of the air supply / exhaust hose (27), and are connected to the uppermost outer frame surrounding member (36). A steady buoyancy member (23) was attached to form buoyancy imparting means (20).

  The uppermost part of the side surface of the outer frame is connected to two independent buoyancy members (21) on the water surface by 2m traction means (60) and extends from the uppermost variable buoyancy member. A hose (27) was connected to the steady buoyancy member (21) to complete a cylindrical outer frame side surface (31) having buoyancy imparting means.

Gravity that balances buoyancy is necessary to maintain a stable attitude of organic reefs.
The ship bottom (13) forming the lower surface (33) of the outer frame needs to have a bulk specific gravity higher than 1 in order to sink downward, and the underwater of organic matter (FIG. 6-51) filling the inner space of the outer frame. The ship bottom (13) was filled with sand as a heavy object (FIG. 6-63) within a range in which the sum of gravity was less than that of the buoyancy imparting means (20).

  Solid plant organic matter (FIGS. 7-50) having a predetermined volume to be inserted inside the outer frame is described in Example 2.

  The upper surface (32) of the outer frame into which the organic matter was inserted was closed using the synthetic resin net (34), and the organic reef (1) that can be expanded and contracted in the vertical direction shown in FIG. 1 was completed.

  2 and 3 are side views showing a process of levitating to regenerate the organic reef shown in FIG. 1. FIG. 2 shows the floating buoyancy member (24) having no buoyancy at the top and the buoyancy in the middle stage. The variable buoyancy member (24) that does not have is filled with pressurized air and becomes a variable buoyancy member (25) with buoyancy, and then floats up to the middle stage. FIG. It is the side view showing the state which became a fluctuating buoyancy member (25) with full buoyancy and floated up to the ship.

The outer frame orbiting member (36) is provided with a predetermined distance of 16m (Fig. 6-41) between the outer periphery of the vessel (12) and connected to the outer periphery of the vessel using the outer frame vertical rope member (35). .

  An outer frame forming member (34) made of the synthetic resin net is stretched on the outer side of the outer frame vertical rope member (35) that connects the marine peripheral portion and the uppermost outer frame rotating member, and the side surface of the cylindrical outer frame (31).

  An outer frame orbiting member (37) that matches the middle portion of the side surface of the cylindrical outer frame is manufactured by the VP150, and two outer frame orbiting members are added to the uppermost outer frame orbiting member (36). Three steady buoyancy parts (23) constitute the side surface of the outer frame.

  A total of 6 variable buoyancy members (24) are attached to the outer periphery of the ship and 2 on the outer periphery of the outermost frame, and a total of 6 variable buoyancy members are connected by a supply / exhaust hose. The variable buoyancy member is connected to the air supply / exhaust hose (27), one of which reaches the water surface.

The attitude control rope member, which is connected to the ship's peripheral edge, passes through the outside of the synthetic resin net on the side of the outer frame, passes through the inside of the two outer frame surrounding members (37) in the middle, The outer frame orbiting member (36) circulates from the outside to the inside, exits again near the side, passes through the cavity of the movable heavy object (64) on the outside of the side of the outer frame, and the tip is placed on the bottom of the ship. Connected.
The attitude control rope members were equally distributed in the left and right positions at two locations on the front and rear sides of the ship, and a total of four pieces were installed.

  Solid plant organic matter (Fig. 6-50) is inserted into the inner space of the outer frame, and the outer frame forming member (34) made of the synthetic resin net is stretched on the outer frame upper surface (32), thereby completing the organic matter reef. did.

With reference to FIG.
When resurfacing the organic reefs shown in Fig. 5, pressurized air is injected over the surface of the water, and the volume of the variable buoyancy member (24) that does not have the buoyancy at the top first increases and changes with buoyancy. The buoyancy member (25) starts to ascend, and then the floating buoyancy member (24) attached to the periphery of the ship and having no buoyancy becomes the variable buoyancy member (25) having buoyancy and the ascent is completed.

  As the float floats, the side surface of the cylindrical outer frame contracts, the posture control rope member (38) is loosened, and the posture control rope member is pulled outward by the added movable heavy object (64). As the attitude control rope member becomes longer, the movable heavy object moves away from the ship bottom and moves to the lowest point.

  The uppermost outer frame orbiting member (36) has a diameter approximately twice as long in the length direction of the ship's peripheral edge and approximately three times as large in the width direction, and the outer frame is directed outward by the attitude control rope member as it floats. FIG. 7 shows a composition in which the outer frame orbiting member (36) floats in order from the top and finally the ship floats in the center.

Reference is made to FIG.

The gap (43) through which the fry and small fish of this embodiment can pass is 12 cm, and the distance (42) between the uppermost part of the outer frame and the water surface is 2 m.

  Of the solid plant organic matter (50), the thinning material and roadside tree selection material have a specific gravity of 1.3 to 1.5 immediately after harvesting with moisture, so no processing is required if used immediately. The device has been devised to reduce the number of curved parts by cutting into a shape that is easy to transport.

Among the solid plant organic matter (50), the bamboo material is cut off the branches, the main trunk is cut into 3 to 5 m, and then divided into 2 to 4 parts to break the hollow structure, and 10 to 30 are collected. I united with a rough rope.
Tsukuso bamboo just after felling, which destroyed the hollow structure, was submerged in water with a bulk specific gravity of 1.3, but the moisture in the fiber evaporated and lightened over time, so it was used immediately after cutting.
The branch part was used by binding only the branch part.

  The solid plant organic matter (50) having a predetermined volume to be put into the inner space of the outer frame is a basic material of the present invention, but the shape of bamboo material and wood is not fixed, so the drawing is only part of the circle.

The side surface of the cylindrical outer frame shown in the side view of FIG. 13-A is composed of an outer frame rotating member (37) in which enlargement and reduction are mixed, and a part of the uppermost outer frame rotating member (36) is directly below. It is smaller than the outer frame surrounding member (37).
In addition, the posture control rope member (38) is configured to pass only through the enlarged portion, thereby facilitating posture control during ascent.

  The side surface of the cylindrical outer frame shown in the plan view of FIG. 13-B has three hexagonal outer frame revolving members (37) to which six variable buoyancy members (24, 25) are attached. The outer frame orbiting member (37) without hexagonal and octagonal variable buoyancy members is composed of three pieces, and four variable buoyancy members (24, 25) are attached to the periphery of the ship.

As described above, the present invention uses waste, minimizes the input of new energy, and proposes the restoration of fishery resources.
Forests nurture the sea, this important issue has been reaffirmed, and fishermen who are planting trees are beginning to appear, but planted forests grow into splendid coniferous forests by planting three times as many young trees and repeating thinning. Abandoned due to the depopulation and aging of the mountain village, the overgrown plantation has squeezed its last power according to the instincts of the organism and scattered pollen several times.
Thinning and growing into rich forests also contributes to reducing medical expenses for hay fever countermeasures.

  Waste trees selected from roadside trees and planted trees are incinerated by wasting fossil fuels while containing moisture, and their effective use is desired.

There are also areas where forests are being destroyed by the advance of bamboo.
The old bamboo forest damage was to extend to the adjacent land by extending the rhizome, but the current bamboo forest damage is a few trees that suddenly appeared on the border areas such as roads grew in a month or two Covering the sky, stretching the underground stems vertically and horizontally, quickly transforming into a bamboo forest while destroying the forest, transforming into a ruined bamboo forest that even wild animals cannot enter.
The laurel forest is deeply rooted in the ground, stores rainwater as a green dam, and forms a rich forest that nurtures diverse organisms. Forming a biological layer, the withered bamboo gaps deeply into the ground, causing large-scale landslides.
Cutting oligotrophic bamboo that has entered the forest is a simpler and more effective method than planting and growing the forest, and the restoration of a rich forest is eagerly desired.
These phenomena are prominently seen in the southern region of Honshu, including Kyushu and Shikoku, and are still happening near Satoyama, but in a few years ahead, they spread to the depths of the mountains and progressed. In the near future, it is fully predicted that forests in Japan will become unrenewable, and immediate measures are imminent.

On the other hand, in the sea, Japan's coastal waters, where many seaweeds such as kombu, wakame, kajime, and hondawala were once prosperous, were supported by the rich forests behind them.
Forests are lost, earth and sand flows in through development, shallow waters and tidal flats filled with purification functions are lost due to vertical revetment, the supply of organic matter is divided by the dam lake, and the limestone layer is expanded by coral spiders on the sea floor, and the burning of the toast is widespread However, seaweed disappeared and the school of fish disappeared, and Satoumi was devastated.
Even in subtropical waters, coral reefs that are killed by coral reefs that live with a variety of organisms, by abnormal breeding of giant starfish, by inflow of red soil, or by rising seawater temperature, are expanding and the sea desert is spreading. .
The decrease in seaweed and coral reefs naturally depletes fish that lay eggs only on seaweed and fish grown by seaweed, and it is necessary to restore a broken food chain.

The limited sea area near large cities is supplied with a large amount of nutrients such as nitrogen and phosphorus dissolved in water, causing microorganisms to explode and causing adverse effects such as red tide, but on the other hand, many coastal sea areas However, there is a shortage of organic and mineral supplies.
Rivers that carry precious organic resources grown in forests to the ocean, many dams lay down, water is stagnated, organic matter is dammed up, and airlessly decomposed at the bottom of hypoxic lakes, and satoumi is exposed to poor nutrition. ing.
Satoumi lives only when it is connected to abundant forests. Instead of rivers cut off by dam lakes, the present invention completes the food chain by providing solid organic matter to the ocean.

However, even if the permanent recovery of fishery resources in Satoumi is a major economic effect, it is not effective for high-priced fishing reefs because there is no economic effect on costs.
The present invention supplies a large amount of solid organic matter, which is the origin of a sustainable food chain, and focuses on means for regenerating a fishing reef when the organic matter is decomposed and lost, and uses second-hand or abandoned fiber-reinforced plastic ships. By doing so, it is possible to make cheap organic fishing reefs, and permanent fishing resources are secured by large-scale reefs connected by cheap organic fishing reefs, or satoumi is revived by combining with existing stationary net fishing and advance into the open ocean Even if it is possible to make a living, the fishing village will be activated.
In Satoyama, the utilization of unused resources such as waste bamboo and woody organic materials will bring back new employment and vitality, and can be expected to have a great economic effect connecting fishing villages and mountain villages.
