Description

  The present invention is a fishing reef in which a used or abandoned fiber reinforced plastic ship (commonly called FRP ship) is connected to a frame containing a hollow portion, and unused bamboo or woody organic matter is inserted into the internal space of the frame. It relates to organic fishing reefs that can float and sink, aiming to restore fishery resources.

Conventional fishing reefs using organic matter are often based on ideas based on onshore structures, although they are effective in collecting fish.Recognizing the degradation of microorganisms and insects caused by diet as short-lived, taking into account regeneration. There are not many reefs.
For example, there is a ginger with a function of ups and downs, but the structure of the ups and downs is closed, or in the open type, attachment of aquatic organisms is not considered, and it is a culture method for specific fish species, It is not an invention intended to utilize used or abandoned ships, or unused resources such as bamboo or wood.

Even though there are various problems such as global changes due to an increase in carbon dioxide, overfishing due to evolution of fishing methods such as fish detectors, wasteful use of resources due to cultivation of specific fish species and environmental destruction, The impact of the decline of broad-leaved forests in the inland and the devastation of plantation forests is large, and in addition, landfills have been contaminated by industrial wastewater and domestic wastewater, and have been devastated.
The present invention focuses on the marine environment where many satoumi are placed, and aims to revitalize fishery resources in line with the natural cycle by making effective use of discarded organic resources.

Fiberglass reinforced plastic (known as FRP ship) is a lightweight, high-strength, highly durable product that is damaged when it is dismantled. As a result, it is difficult to collect, transport, and dismantle, and new energy is needed to recycle scrapped ships.
The present invention is estimated to be 140,000 ships, which is a major social problem, and in addition to neglected boats, the number of ships exceeding 10,000 ships will be abandoned every year. Therefore, inexpensive and effective recycling technology and new energy are consumed. Reuse method that does not work.

In many inner bays and coastal waters due to revetment work, shallow waters and tidal flats full of purification functions are lost, and the supply of valuable organic matter is divided by dams and incinerated by human activities.
In the present invention, by supplying a large amount of organic matter, food is provided and propagated to aquatic organisms, which become fish food, and a purification function is promoted by appearance of a shallow sea environment with countless small spaces and large surface areas. The aim is to restore permanent fishery resources in the satoumi by increasing the photosynthesis by the solids and sun rays that are used to lay seaweeds and providing a starting point for a broken food chain.
The same phenomenon is also seen in freshwater lakes and brackish lakes, and is an issue with a view to improving the environment of lakes.

Waste bamboo from felling bamboo forests that are destroying the forest with a tremendous momentum, thinned wood from devastated artificial forest, selected waste from roadside trees, offcuts generated at sawmills, waste wood used in construction, and these obstacles Wastes that are handled as waste are valuable organic substances that plants have created by absorbing carbon dioxide, and their effective use is a return to the forest and should not be easily incinerated.
The purpose of the present invention is to provide these useful organic substances to Satoumi. Although organic substances are decomposed and destroyed by beetles and bark beetles, they need to be replenished, but this destroying aquatic organism is an important bait for fish. Yes, what is destroyed is a healthy carbon cycle, and human beings must incinerate it without breaking the smooth carbon cycle.
A large amount of nutrients that are biased by nitrogen and phosphorus are supplied in limited areas near large cities, but many coastal areas are suffering from a shortage of organic matter and minerals.
An object of the present invention is to provide valuable organic resources grown in forests to places where they are most needed.

In the past, the rich forest resources of satoyama were transported to the satoumi by the rivers, became abundant marine resources and returned to satoyama, and the carbon cycle through organic matter was naturally carried out.
Forests are destroyed and incinerated by current human activities that consume much, rivers are dammed up by dams, satoumi is devastated following satoyama, and the primary industry is in trouble.
The object of the present invention is to supply a large amount of food to aquatic organisms and fish by providing solid organic matter to the marine area where the organic matter synthesized by the forest is blocked by dams and depleted of nutrients and longed for. Providing that means.

The frame unit is connected to the above-mentioned hull, and the lower surface at the same position as the lowermost surface of the cavity is open and the other parts are closed. Inserted into the underwater gravity of the frame and the internal space of the frame As long as the sum of the underwater gravity of the bamboo or woody organic material does not exceed the underwater gravity that balances with the buoyancy that occurs when the cavity in the frame unit housing is filled with air, sand, stone, ore, Or, it is an organic material that can float and sink, characterized by filling the bottom of a fiber reinforced plastic ship with heavy objects such as iron scraps, ceramics, concrete lump waste, or concrete to provide underwater attitude control and subsidence functions. Provide reefs.

  The ventilation hose connected to the above-mentioned protruding part has an opening / closing function with one side reaching the water surface, and has a function capable of arbitrarily determining the amount of air enclosed in the hollow part included in the housing. Even if the bottom of the fiber reinforced plastic hull is V-shaped, the underwater posture is stable. Provide organic fishing reefs that can float and sink.

  An object of the present invention is to provide an organic bait to aquatic organisms and fish, and the upper surface of the internal space of the frame unit has a gap having a predetermined interval and an opening having an opening / closing function, and the side surface is A gap that allows small fish to freely pass through inside and outside of the frame and has a gap that can prevent the separation of divided bamboo or woody organic matter at the beginning of insertion, and the lower surface is fiber reinforced plastic with the opening open It is connected to the outer periphery or inner edge of the ship's hull, and when bamboo or woody organic matter inserted into the inner space of the connecting frame is reduced or disappears, pressurized air is introduced into the cavity in the connecting frame body. A floating and sinking type organic matter reef characterized by being able to float a fishing reef by injecting, opening an upper opening of a connecting frame and replenishing bamboo or woody organic matter.

  If the sum of the underwater gravity of the above-mentioned swellable organic reefs becomes heavier than the buoyancy that occurs when the cavity in the frame unit enclosure is filled with air, or if it is necessary as a suspended fishing reef, It is characterized by the additional use of buoyancy imparting means, and as an installed reef or suspended reef, waste bamboo materials that are unused resources, thinning waste materials from artificial forests, scrap materials generated at sawmills, selected waste materials of street trees, Providing an organic fishing reef that can be used to make effective use of waste such as waste wood from buildings.

Organic matter produced on land is dammed in the dam lake and decays at the bottom of the hypoxic lake, or is incinerated and does not reach the sea, and the coastal seaside is lost due to vertical revetment by landfill, and the satoumi is devastated For fishermen who have advanced into the open ocean, but have exhausted a limited number of resources through modern fishing methods such as fish finder, etc., and have been forced to break down profitability due to soaring fuel, permanent fishery resources can be grown in Satoumi. Is of great significance.
The organic fishing reef using a used or abandoned ship of the FRP ship of the present invention provides organic individuals near the sea surface, the shallows are reproduced, and the aquatic organisms that feed on them reproduce to ensure fish food, Seaweeds land, a huge space is created three-dimensionally to ensure the safety of larvae and larvae, complete the food chain, and restore the carbon cycle that was cut off by human activities.
The recovery of permanent fishery resources in Satoumi can save time and money, and the natural benefits of Satoumi and the great economic benefits can be expected without consuming expensive limited fuels and finite small fish.

  The present invention is a method for effectively using a used or abandoned FRP ship, which is difficult to recycle due to the lamination of different materials, and it is new by simply removing the deck, engine, steering device, fuel tank and other parts. Without the need for extra energy, taking advantage of the light weight, high strength, and corrosion resistance of FRP ships as they are, reducing the manufacturing cost by connecting mass-produced parts to assembled frame units, and building large hulls on land This is a reuse method that reduces the transportation cost by processing at the port without transporting it and linking it with the installation location.

The reason why large numbers of fish can survive with a limited amount of ginger is that they are fed daily.
A large amount of fish can live in the North Sea because there is abundant food.
The present invention is a fishing reef that utilizes unused woody organic matter as a means for generating a large amount of aquatic organisms in order to secure fish food, and is an invention that considers a method for replenishing organic matter that is lost by aquatic organisms' diet .
In order to replenish woody organic matter into the seabed or underwater reefs, a large crane ship is usually required.However, the present invention floats while maintaining a normal posture simply by blowing compressed air into the reef frame. It is regenerated just by inserting organic matter, and by substituting again by releasing compressed air, it is revived as an organic matter reef, and it is a rational reef that focuses on inexpensive means of regeneration.

  The floatable reef using a used or abandoned ship of the FRP ship of the present invention has a function to sunk the reef deeply underwater during stormy weather and avoid the influence of waves, and to float near the water surface in good weather. There is an advantage that can be done by simple operation to adjust.

The current situation in the coastal area of Japan is that coral breeding is covered with a white limestone layer and the burning of sea bream with no visible seaweed and fish is spreading and progressing.
In the undernourished sea area, which is one of the conditions for coral breeding, the river that transported the organic matter produced by the forest to the sea is blocked by the dam, and the organic matter settles in the dam lake and decomposes in a low oxygen state One of the causes is thought to be the interruption of the carbon cycle synthesized by the forest.
By supplying a large amount of organic matter so as to cover the upper surface of the coral, the present invention can be expected to revive seafood and deplete fishery resources, and eventually cause the coral to decline.

  The FRP ship used a small Japanese ship that was abolished with a total length of 4.2 m, a total width of 1.5 m, and a depth of 0.6 m, and removed the hatch and ikes lids and used the hull as it was.
