Description

本願発明は、海底に設置された外枠が軟質部材からなる筒状の外枠側面を有し、外枠の内部空間に固体の植物性有機物を挿入し、水棲生物を介した食物連鎖によって餌箱機能を持った漁礁に関する。   The invention of the present application has a cylindrical outer frame side surface made of a soft member, and the outer frame installed on the seabed inserts solid plant organic matter into the inner space of the outer frame, and feeds it by a food chain through aquatic organisms. Relating to a fishing reef with a box function.

例えば、棒状或いは索状の材料を用いて籠状に形成した枠体中に、間伐材や木材チップを含む林産物をネット状の袋に収納し、魚類の餌となる生物の育成増殖を図り、海藻類の付着育成を図り、魚類の定着育成を図る技術があるが、林産物をネット状の袋に入れ、海中に設置した籠状に形成した枠体中に入れるだけである。
間伐材などの林産物を再生する手段は、海中設置用構造体を引上げる方法であり、膨大な費用が必要である(例えば特許文献1参照)。
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).

例えば、6面体をしたコンクリートの枠体に、間伐材などの木材を井桁状または格子状に組み付けた平面ユニットを複数段積層し、コンクリートの枠体に入れて鋼材で固定し、上部に自然石を載置した魚礁技術がある。
この魚礁技術は、コンクリートの枠体及び鋼材と木材の平面ユニットとの間で、耐用年数に大きな開きがあり、集魚効果を伴う木材の補充手段が全く考慮されていない。(例えば特許文献2参照)。
For example, a hexahedron concrete frame is stacked with a plurality of flat units in which wood such as thinned wood is assembled in a grid or lattice shape, placed in a concrete frame and fixed with steel, and natural stone is placed on the top. There is a fish reef technology.
In this fish reef technology, there is a great difference in the service life between the concrete frame and the steel and the flat unit of wood, and no means for replenishing wood with a fish collection effect is taken into consideration. (For example, refer to Patent Document 2).

特開2008−048687号JP 2008-048687 A 特開2008−029267号JP2008-029267

特許文献1に記載した背景技術では、間伐材等の林産物をネット状の袋に収納し魚類の定着育成を図り海底或いは湖底に設置する技術があるが、その食物連鎖により破壊される有機物の交換にはクレーン船を要し、簡単に再生する方法が考慮されていない。
特許文献2においても消失する木材の交換が全く考慮されていない。
In the background art described in Patent Document 1, there is a technique in which forest products such as thinned wood are stored in a net-shaped bag and the fish is fixed and cultivated and installed on the seabed or lake bottom. Requires a crane ship and does not consider how to regenerate easily.
Even in Patent Document 2, replacement of lost wood is not considered at all.

従って、竹材、間伐材、街路樹や植木の選定廃材、製材過程で生じる端材や廃木材などの有機物は、水棲生物の食餌や分解によって短期間で消失するのであって、高度な加工を要する事なく安価に簡単に補充する方法を発明し、永続的な魚礁を提供する事を課題とする。   Therefore, organic materials such as bamboo, thinned wood, selected roadside trees and planted wood, scraps and waste wood produced during the sawmilling process will disappear in a short period of time due to the diet and decomposition of aquatic organisms, and require advanced processing. It is an object of the present invention to provide a permanent reef by inventing a method for replenishing easily and inexpensively.

前記の課題を解決するため本願発明の餌箱漁礁は、外枠の内部空間に固体の植物性有機物を挿入した餌箱漁礁であって、外枠は、筒状の外枠側面を有して構成されており、筒状の外枠側面は、所定間隔を有する筒状の軟質部材で構成され、下方が海底に接するように配置されて鉛直方向に使用し、下方の少なくとも一部が固定手段によって海底に固定され、或いは下方の少なくとも一部に重量物が付帯されて海底に略固定され、上方の少なくとも一部に浮力付与手段が接続されており、外枠の内部空間に所定体積を持つ固体の植物性有機物が挿入されている   In order to solve the above-mentioned problem, the bait reef of the present invention is a bait reef in which a solid plant organic matter is inserted into the inner space of the outer frame, and the outer frame has a cylindrical outer frame side surface. The side surface of the cylindrical outer frame is configured by a cylindrical soft member having a predetermined interval, and is arranged so that the lower part is in contact with the seabed and used in the vertical direction, and at least a part of the lower part is a fixing means. Is fixed to the seabed, or is attached to at least part of the lower part and is substantially fixed to the seabed, and buoyancy imparting means is connected to at least part of the upper part, and has a predetermined volume in the inner space of the outer frame. Solid plant organic matter is inserted

前記の課題を解決するため本願発明の餌箱漁礁は、水中にある外枠の内部空間に固体の植物性有機物を挿入した餌箱漁礁であって、外枠は、筒状の外枠側面を有して構成されており、筒状の外枠側面は、所定間隔を有する筒状の軟質部材で構成され、下方が海底に接するように配置されて鉛直方向に使用し、下方の少なくとも一部が固定手段によって海底に固定され、或いは下方の少なくとも一部に重量物が付帯されて海底に略固定され、上方の少なくとも一部に浮力付与手段が接続されており、外枠の内部空間に所定体積を持つ固体の植物性有機物が挿入されている   In order to solve the above problems, the bait reef of the present invention is a bait reef in which a solid plant organic matter is inserted into the inner space of the outer frame underwater, and the outer frame has a cylindrical outer frame side surface. The side surface of the cylindrical outer frame is composed of a cylindrical soft member having a predetermined interval, and is arranged so that the lower side is in contact with the seabed and used in the vertical direction, and at least a part of the lower side Is fixed to the seabed by fixing means, or a heavy object is attached to at least a part of the lower part and is substantially fixed to the seabed, and buoyancy imparting means is connected to at least a part of the upper part. Solid plant organic matter with a volume is inserted

筒状の外枠側面は、ネット状部材、ロープ部材等の屈曲自在な軟質部材でもって筒状に形成されており、波浪や潮流に対し柔軟に対処できる。   The side surface of the cylindrical outer frame is formed in a cylindrical shape with a flexible member such as a net-like member or a rope member, and can flexibly cope with waves and tidal currents.

この軟質部材は、稚魚や小型魚が通過できるが、外枠の内部空間に挿入する植物性有機物の離散を防止できる程度の空隙を持つ部材で構成されている。   This soft member is configured by a member having a space that allows fry and small fish to pass through but prevents the plant organic matter inserted into the inner space of the outer frame from being dispersed.

この空隙は、稚魚や小型魚にとって水棲生物を餌として捕食するために、或いは大型魚から身を守るための住処となるために、恒久的な漁業資源確保のために重要な手段であって、魚種によって異なるが自由に通過できる30mm〜120mmが望ましい。   This gap is an important means for securing permanent fishing resources for fry and small fish to feed on aquatic organisms as a bait or to protect themselves from large fish, Although it differs depending on the fish species, 30 mm to 120 mm which can pass freely is desirable.

筒状の外枠側面の所定間隔は、外枠側面の高さであって干潮時水深の範囲内にあり、水深、潮流、波浪などの海況に応じて設定するが、下方が海底に接し、上方は干潮時水面〜水深4m程度を目安としている。   The predetermined interval of the cylindrical outer frame side is the height of the outer frame side and is within the range of water depth at low tide, and is set according to the sea conditions such as water depth, tidal current, waves, etc., but the lower part touches the sea floor, The upper part is a rough standard from the water surface at low tide to a depth of about 4m.

筒状の外枠側面の下方は、固定手段によって海底に固定されるか、或いは重量物を付帯する事によって海底に略固定され、波浪や潮流に耐えて移動しない必要がある。   The lower part of the side surface of the cylindrical outer frame is fixed to the sea bottom by a fixing means, or is substantially fixed to the sea bottom by attaching a heavy object, and needs to withstand waves and tidal currents and not move.

筒状の外枠側面の上方は、少なくとも一部に浮力付与手段が付加される事によって筒状の軟質部材を直立させ、早い潮流では変形を余儀なくされるものの潮流の停止と共に復元し、筒状の外枠側面の形状を保持する。   Above the side surface of the cylindrical outer frame, the cylindrical soft member is made upright by adding buoyancy imparting means to at least a part, and it is deformed in the early tide, but it is restored when the tide is stopped, The shape of the side of the outer frame is retained.

浮力付与手段は、内部に発泡樹脂が充填された容器からなる浮力部と、或いは密封された硬質容器からなる浮力部が、単独で或いは混在して形成する。   The buoyancy imparting means is formed of a buoyancy part made of a container filled with foamed resin inside and a buoyancy part made of a sealed hard container, either alone or in combination.

浮力付与手段は、台風などの荒天時には取外して外枠側面を海底に沈め、台風の通過後に再び浮力付与手段を取付けて餌箱魚礁を復元する事が出来る。   The buoyancy imparting means can be removed during stormy weather such as a typhoon and the outer frame side is sunk on the seabed.

外枠の底は、筒状の外枠側面が海底に接した内側と、筒状の外枠側面が外側にはみ出した部分の合計である。   The bottom of the outer frame is the total of the portion where the cylindrical outer frame side surface is in contact with the seabed and the portion where the cylindrical outer frame side surface protrudes outward.

所定体積を持つ固体の植物性有機物は、粉末や顆粒状の物質を除く竹類や木質系の有機物であって、筒状の軟質部材から容易に離脱しない体積をもち、好ましくは直径、巾、長さの合計が30cm以上の大きさであって、付着している昆虫などは同じ有機物として概念する。   Solid plant organic matter having a predetermined volume is bamboo or woody organic matter excluding powder and granular substances, and has a volume that does not easily separate from the cylindrical soft member, and preferably has a diameter, width, The total length is 30 cm or more, and attached insects are considered as the same organic matter.

乾燥した植物性有機物は、躯体中の水分が蒸発した痕が空洞となって嵩比重が1より小さくなるため含水させる前処理が必要であるが、水分を含んだ植物性有機物の大多数は嵩比重が1以上であり、外枠内部空間に挿入した場合は底に沈む。   Dried plant organic matter requires pretreatment to contain water because traces of evaporation of moisture in the rods become cavities and the bulk specific gravity is less than 1, but the majority of plant organic matter containing moisture is bulky. The specific gravity is 1 or more and sinks to the bottom when inserted into the inner space of the outer frame.

筒状の外枠側面上方の内側が外枠上面であって、外枠上面の少なくとも一部が上面形成部材でもって閉塞されているが、閉塞は必須条件ではない。   The inner side above the cylindrical outer frame side surface is the upper surface of the outer frame, and at least a part of the upper surface of the outer frame is blocked by the upper surface forming member, but the blocking is not an essential condition.

外枠上面の少なくとも一部を閉塞するための上面形成部材は、ネット、ロープ、パイプ、棒状部材の内少なくとも1種以上で構成されている。   The upper surface forming member for closing at least a part of the upper surface of the outer frame is composed of at least one of a net, a rope, a pipe, and a rod-shaped member.

水棲生物の食餌によって消失した有機物を補充する為、上面形成部材の少なくとも一部に開閉機能を有する開口部が接続されており、或いは水面に達する高さを持つ開口部が接続されており、有機物の挿入口として利用する。   In order to replenish organic matter that has disappeared due to the diet of aquatic organisms, an opening having an opening / closing function is connected to at least a part of the upper surface forming member, or an opening having a height reaching the water surface is connected. Used as an insertion slot.

筒状の外枠側面を直立させる手段として、或いは航行する船舶の目印として、或いは餌箱漁礁の在処を特定するため、筒状の外枠形成部材が、或いは上面形成部材が、或いはその両方が、牽引手段を介して水面にある浮力体に接続されている。   The cylindrical outer frame forming member, the upper surface forming member, or both are used as a means for erecting the side surface of the cylindrical outer frame, as a mark of the vessel to be navigated, or for specifying the location of the bait reef. It is connected to the buoyancy body on the water surface through the traction means.

牽引手段は、海底の固定手段と水面にある浮力体とを結ぶ手段であるが、筒状の外枠側面に接している部分は外枠形成部材としての機能を併せ持ち、外枠側面の下方で固定手段に接続する部分は固定手段としての機能を併せ持つ。   The traction means is a means for connecting the seabed fixing means and the buoyant body on the water surface, but the portion in contact with the cylindrical outer frame side surface also has a function as an outer frame forming member, and is located below the outer frame side surface. The portion connected to the fixing means also has a function as a fixing means.

少なくとも一部の固定手段は、下方が海底に固定され、上方が海中に達して所定間隔の少なくとも一部を占める高さを有して略固定され、この固定手段に外枠形成部材が接続されて外枠を形成している。   At least a part of the fixing means is fixed to the seabed at the lower part and substantially fixed at a height that occupies at least a part of the predetermined interval with the upper part reaching the sea, and the outer frame forming member is connected to the fixing part. The outer frame is formed.

餌箱魚礁を再生するため、外枠の内部空間に挿入する植物性有機物は、所定体積に切断されて外枠の内部空間に挿入された、所定体積を持つ個体の植物性有機物を提供する。   In order to regenerate the feeding box fish reef, the plant organic matter inserted into the inner space of the outer frame is cut into a predetermined volume and inserted into the inner space of the outer frame to provide an individual plant organic matter having a predetermined volume.

本願発明で記す満潮時水面或いは干潮時水面或いは水面とは、大潮小潮、或いは波浪の影響によって常時変動している為、水面下略60cmから水面上略60cmをもって水面と定義する。   The high tide or low tide water surface or water surface described in the present invention is constantly changing due to the influence of the tidal and tides or waves, so it is defined as the water surface from approximately 60 cm below the water surface to approximately 60 cm above the water surface.

本願発明を利用する事によって、未利用の竹材や森林資源が水棲生物の餌となり、水棲生物が魚類の餌となって食物連鎖が完成し、同時に稚魚や幼魚にとって安全な住処が提供される。
本願発明は、稚魚や小型魚にとっては自由に出入りできる餌箱であって、餌箱の外側がオープンスペースの生簀の概念に基づき漁業資源の増殖が期待できる。
By utilizing the invention of the present application, unused bamboo and forest resources become feed for aquatic organisms, and aquatic organisms become feed for fish to complete a food chain, and at the same time, a safe place for fry and young fish is provided.
The present invention is a bait box that can be freely entered and exited for fry and small fish, and can be expected to proliferate fishery resources based on the concept of an open space ginger outside the bait box.

菱型をした植物性有機物の餌箱漁礁12について、図1の側面図に基づき記述する。
筒状の外枠側面23を構成する側面形成部材24は、直径6mmの合成樹脂製ロープで製作したネットである。
このネットは、75mm×120mmの空隙を持つ軟質部材で、巾6m、長さ方向に12mの長方形をしており、4枚を製作した。
A rhombus-shaped plant organic matter bait reef 12 will be described with reference to the side view of FIG.
The side surface forming member 24 constituting the cylindrical outer frame side surface 23 is a net made of a synthetic resin rope having a diameter of 6 mm.
This net is a soft member having a gap of 75 mm × 120 mm, and has a rectangular shape with a width of 6 m and a length of 12 m, and four pieces were produced.

このネット4枚は、長さ方向の両端を4本の側面形成部材24の一部であり牽引手段43でもある直径24mmの合成樹脂製ロープに順々に接続する事により、巾6m(高さ)の筒状の軟質部材26が形成された。
従って、この筒状の軟質部材26は、1辺が12mの四角形(後に菱型に設置する)であって、所定間隔38として6mの高さを持ち、側面に75mm×120mmの空隙を持っている。
The four nets are connected to a synthetic resin rope having a diameter of 24 mm, which is a part of the four side surface forming members 24 and also the traction means 43, in order in the longitudinal direction. ) Of the cylindrical soft member 26 was formed.
Therefore, this cylindrical soft member 26 is a square having a side of 12 m (to be installed later in a rhombus), has a height of 6 m as a predetermined interval 38, and has a gap of 75 mm × 120 mm on the side surface. Yes.

潮流40と平行方向を長辺側とし、略22mの間隔を設けた海底45位置の2箇所と、その中央で直角に交わる方を短辺側とし、略10mの海底45位置2箇所の合計4箇所に、コンクリート製杭を打ち込み固定手段42とした。   A total of 4 locations with two locations at the bottom of the sea bottom 45 at a distance of approximately 22 m and a short side that intersects at right angles at the center, with two sides approximately 45 m at the bottom, with the direction parallel to the tide 40 as the long side. Concrete piles were driven into the places to form fixing means 42.

この4箇所の固定手段42に、筒状の軟質部材26と接続された4本の牽引手段43の下方を接続し、筒状の外枠側面が菱型となって海底に固定された。
この時、筒状の外枠側面下方にある4本の牽引手段43は、固定手段42の機能を併せ持っている。
The four fixing means 42 were connected to the lower side of the four traction means 43 connected to the cylindrical soft member 26, and the cylindrical outer frame side face was fixed to the seabed with a diamond shape.
At this time, the four traction means 43 below the side surface of the cylindrical outer frame also have the function of the fixing means 42.

海底に固定された筒状の外枠側面23は、最上方に浮力付与手段30を取付ける事によって、筒状の軟質部材26が水中で直立した。   By attaching the buoyancy imparting means 30 to the uppermost side of the cylindrical outer frame side surface 23 fixed to the seabed, the cylindrical soft member 26 stands upright in water.

この浮力付与手段30は、内部に発泡樹脂を充填した6kg/1個の浮力を持つ長円形のフロート16個を側面形成部材24である直径24mmの合成樹脂ロープに通し、1辺に4個の略均等割で筒状の軟質部材の最上方に接続した。   This buoyancy imparting means 30 passes 16 oval floats having a buoyancy of 6 kg / piece filled with foamed resin inside through a synthetic resin rope having a diameter of 24 mm, which is a side surface forming member 24, and 4 pieces per side. It connected to the uppermost part of the cylindrical soft member at substantially equal splits.

本実施例の所定間隔38は、6mに設定したので、外枠上面が干潮時水面より0.6mの深さになった。   Since the predetermined interval 38 of this example was set to 6 m, the upper surface of the outer frame was 0.6 m deeper than the water surface at low tide.

筒状の外枠側面に接続された牽引手段43は、下方が海底45に固定された後、上方は満潮時の水面に達するまで延長し、水面にある浮力体34に接続した。   The traction means 43 connected to the side surface of the cylindrical outer frame was fixed to the sea bottom 45 at the lower side, and then extended upward until it reached the water surface at high tide, and connected to the buoyant body 34 on the water surface.

水面にある浮力体34は、内部に発泡樹脂を充填し24kg/1個の浮力を持つ球状のフロートを使用した。
球状のフロートは、餌箱魚礁12を牽引すると同時に、水中の餌箱魚礁の在処を示す標識となる。
As the buoyant body 34 on the water surface, a spherical float having a buoyancy of 24 kg / 1 piece filled with foamed resin inside was used.
The spherical float pulls the bait fish reef 12 and at the same time becomes a sign indicating the location of the underwater bait fish reef.

外枠の底50は、筒状の外枠側面が海底に接した内側の海底45をそのまま利用する部分と、側面形成部材24の一部が外側にはみ出した部分の合計を所定面積39とし、本実施例では略120mである。 The bottom 50 of the outer frame has a predetermined area 39, which is the total of the part using the inner sea bottom 45 where the cylindrical outer frame side surface is in contact with the sea bottom and the part where part of the side surface forming member 24 protrudes outside, In this embodiment, it is approximately 120 m 2 .

筒状の外枠側面23が海底に設置された後、外枠の内部空間に固体の植物性有機物37をランダムに挿入した。
ランダムに挿入した固体の植物性有機物37は、図1及び図4の外枠内部の透視図(円内)36に表示した。
After the cylindrical outer frame side surface 23 was installed on the seabed, solid plant organic matter 37 was randomly inserted into the inner space of the outer frame.
Randomly inserted solid plant organic matter 37 is displayed in a perspective view (inside circle) 36 inside the outer frame of FIGS. 1 and 4.

固体の植物性有機物37は、水分を持った伐採直後の間伐材や街路樹の選定材は嵩比重が1.3〜1.5ある為、扱いが容易な2m程度に切断し、未乾燥のまま使用した。   The solid plant organic matter 37 has a bulk specific gravity of 1.3 to 1.5 for thinned timber and roadside tree materials that have just been cut with moisture. Used as is.

乾燥した植物性有機物は、躯体中の水分が蒸発した痕が空洞となって嵩比重が1未満となるため、予め水中に沈め、充分に吸水させた後使用する。   The dried plant organic matter is used after being submerged in water in advance and sufficiently absorbing water, since the traces of evaporation of moisture in the rod body become cavities and the bulk specific gravity is less than 1.

伐採直後の孟宗竹は、嵩比重が1.3あるため枝部を分離し、主幹部を2m〜4mに切断した後2〜4分割にし、中空構造を破壊してそのまま使用した。   Since the Sosetsu bamboo just after cutting had a bulk specific gravity of 1.3, the branches were separated, the main trunk was cut into 2 to 4 m, and then divided into 2 to 4 parts, and the hollow structure was destroyed and used as it was.

外枠上面は必ずしも閉塞しなければならない必須条件ではないが、外枠上面27を上面形成部材28でもって閉塞し、図1に示す餌箱魚礁12が完成した。   The upper surface of the outer frame is not necessarily an indispensable condition, but the upper surface 27 of the outer frame is closed with the upper surface forming member 28, and the bait reef 12 shown in FIG. 1 is completed.

図2は、図1餌箱魚礁12の上面形成部材28に干潮時に水面まで達する高さを持つ開口部を接続し、有機物の補充に便利な挿入口29を付加した餌箱漁礁の側面図である。   FIG. 2 is a side view of a bait fish reef in which an opening having a height reaching the water surface at low tide is connected to the upper surface forming member 28 of the bait fish reef 12 and an insertion port 29 convenient for replenishing organic matter is added. is there.

里山では、竹林が放置され、間伐材は有効需要が無いために林地に放置され、間伐事業が疎かになって雇用が失われ、高齢化が加速し里山が荒廃している。
都市でも、街路樹の選定廃材は、水分を含んだまま化石燃料を使って焼却処分されているのが現状である。
本願発明は、これらの未利用森林資源を活用する事によって高付加価値を持つ森林資源を創出し、里山の再生を期待するのである。
In satoyama, bamboo forests are abandoned, and thinned wood is left in the forest because there is no effective demand. Thinning operations are neglected, employment is lost, aging is accelerated, and satoyama is devastated.
Even in cities, the selected waste trees of roadside trees are currently incinerated using fossil fuels while still containing moisture.
The present invention creates forest resources with high added value by utilizing these unused forest resources, and expects regeneration of satoyama.

海では、地域によって富栄養と貧栄養の両極端に分かれ、垂直護岸によって浄化機能に満ちた浅瀬や干潟が失われ、有機物の供給がダム湖によって分断され、海底は磯焼けが蔓延し、海藻が消失した海の砂漠が広がっている。
またオープン海域で養殖する海藻や貝類と異なり、限られた空間で高級魚の養殖が行われているが、その多くは大量の資源を餌として消費し、資源の枯渇をますます加速させているのが現状である。
本願発明は、経済活動によって分断された供給ルートを補い、森の有機物を固体の形状で海に提供する事によって飼料生物の増殖を図り、ランダムに投入された有機物が一網打尽に捕獲できない環境と住処を提供して産卵を促し、もって水産資源の持続的な増殖を図る事にある。
In the sea, the area is divided into eutrophic and oligotrophic, depending on the region, the shallow reefs and tidal flats that are full of purification functions are lost by vertical revetment, the supply of organic matter is divided by the dam lake, the seafloor is widespread, and seaweed is spread. The disappearing sea desert is spreading.
Unlike seaweed and shellfish cultivated in open waters, high-quality fish are cultivated in a limited space, but many of them consume a large amount of resources as food and accelerate the depletion of resources more and more. Is the current situation.
The invention of the present application supplements the supply route divided by economic activities, and provides organic matter in the forest to the sea in the form of solids, thereby promoting the growth of feed organisms. The aim is to promote egg laying by providing fishery resources and to sustain the growth of marine resources.

本願発明で使用する有機物が、所定体積を有する固体の植物性有機物である理由には、大きな意味がある。
即ち、水に溶けた窒素や燐、或いは粉末の植物性有機物や動物性有機物の場合は、微生物やプランクトンが爆発的に発生し分解するが故に酸素不足に陥り、或いは大量に死滅したプランクトン等によって赤潮などの弊害をもたらす事になる。
所定体積を有する固体の植物性有機物は、キクイムシやフナクイムシによって食され、或いは表面に付着する微生物によって遅効的に分解され、それらが別の水棲生物によって食され、魚類の餌となって食物連鎖が持続する事になる。
The reason why the organic substance used in the present invention is a solid plant organic substance having a predetermined volume is significant.
In other words, in the case of nitrogen or phosphorus dissolved in water, or in the case of powdered plant organic matter or animal organic matter, microorganisms and plankton are explosively generated and decomposed, resulting in oxygen deficiency or plankton that has been killed in large quantities. It will cause harmful effects such as red tide.
Solid plant organic matter with a certain volume is eaten by bark beetles and beetles, or slowly decomposed by microorganisms adhering to the surface, and they are eaten by other aquatic organisms to become food for fish and feed the food chain. It will last.

しかし、里海に恒久的な漁業資源が復活する事は大きな経済効果であっても、高額の漁礁では費用に対する経済効果が伴わず実効性が無い。
本願発明は、有機物が持続的に分解され消失する事が最大の目的であって、消失した有機物を安価に補充する事に主眼を置いた。
即ち、食物連鎖の原点である森林資源を補充する事によって餌箱としての魚礁が半永久的に再生され、長期間使用する事によって年度単位の単価が安くなり、稚魚を育み、自然の食物連鎖によって恒久的な漁業資源が確保され、漁村の活性化が期待できる。
永続的な森林資源の需要は、山村に新たな雇用を創出し、間伐された山林では高価値の木材が成長し、休漁期の労働力を山村に提供する事によって共通の利益が発生し、或いは地産地消の物々交換が発生し、里海と里山を結びつけた大きな経済効果が期待できる。
However, even if the permanent recovery of fishery resources in Satoumi is a significant economic effect, high-priced fishing reefs have no economic effect on costs and are ineffective.
The main object of the present invention is to continually decompose and dissipate organic matter, and to replenish the disappeared organic matter at a low cost.
In other words, by replenishing the forest resources that are the origin of the food chain, the fish reef as a food box is regenerated semi-permanently, and when used for a long time, the unit price per year is reduced, fry is raised, and the natural food chain Permanent fishing resources are secured and the fishing villages can be activated.
Persistent demand for forest resources creates new jobs in mountain villages, high-value timber grows in thinned forests, and provides common benefits by providing mountain villages with a workforce during the resting season, Alternatively, local exchange for local consumption and local consumption will occur, and a great economic effect connecting Satoumi and Satoyama can be expected.
