Description

この発明は、サンゴ人工養殖装置に関する。   The present invention relates to a coral artificial culture apparatus.

サンゴを人工的に養殖するには、サンゴの小片を海中に保持する。サンゴの小片とは、例えば自然のサンゴなどから、莢肉部を含み、小骨格などと呼ばれる破片を折り取り、適当な付着体にその破片を固定したものをいう。保持する場所は、オニヒトデの食害や泥土の付着から免れる場所でなければならない。   To cultivate corals artificially, a small piece of coral is kept in the sea. The small coral piece refers to, for example, a natural coral or the like that includes a rib portion, breaks a piece called a small skeleton, and fixes the piece to an appropriate attachment. The place to be held must be free from the damage of mud starfish and mud deposits.

そのため、下記特許文献１の装置では、海面に浮かぶ筏等より小骨格を固定した付着体ごと、縦方向へ垂下して、サンゴを生長させて増殖する。
また、下記特許文献２の装置では、海中に固定した複数の浮きにより、水平方向へ多孔質の基質を設け、サンゴを人工的に養殖する。 For this reason, in the apparatus of Patent Document 1 below, the attached body with the small skeleton fixed from the sea bream or the like floating on the sea surface hangs down in the vertical direction and grows and grows corals.
Moreover, in the apparatus of the following patent document 2, a porous substrate is provided in the horizontal direction by a plurality of floats fixed in the sea, and corals are artificially cultivated.

特開平６−３０３８７５JP-A-6-303875 特開２００４−２３６５６１JP2004-236561

しかしながら、特許文献１の装置は、サンゴの小片を縦方向へ垂下する構造であり、海の設置場所は、一定の深さが必要である。特許文献の装置は、海中に複数の浮きを固定した状態が維持できなければならず、よって、やはり一定の深さが必要である。
そして、海の浅い場所に設置する装置を考えると、オニヒトデの食害や泥土の付着の防止が十分ではなくなる。
この発明は、以上の問題点を解決するために、海の浅い場所に設置でき、オニヒトデの食害や泥土の付着の防止が十分な揺りかご式サンゴ人工養殖架台を提供することを目的とする。 However, the device of Patent Document 1 has a structure in which a small piece of coral hangs down in the vertical direction, and a certain depth is required for the installation location of the sea. The device of the patent document must be able to maintain a state in which a plurality of floats are fixed in the sea, and therefore needs a certain depth.
And considering a device installed in a shallow place in the sea, it will not be enough to prevent the damage of the starfish and adhesion of mud.
In order to solve the above-described problems, an object of the present invention is to provide a cradle-type coral artificial culture stand that can be installed in a shallow place in the sea and is sufficient to prevent the damage of the sea urchin starfish and adhesion of mud.

以上の課題を解決するために、第一発明は、海底に固定される架台部分と、この架台部分によって揺動チェーンを介して揺動可能に支持される揺動部分と、を有し、前記揺動部分は、略水平方向へ張り渡されサンゴの小片が取付けられる養殖チェーンと、を有して構成されることを特徴とする揺りかご式サンゴ人工養殖架台である。   In order to solve the above problems, the first invention has a gantry portion fixed to the seabed, and a swinging portion supported by the gantry portion so as to be swingable via a swinging chain, The oscillating portion is a cradle-type coral artificial culture gantry characterized by having a culture chain that is stretched in a substantially horizontal direction and to which a small piece of coral is attached.

第二発明は、海底に固定される架台部分と、この架台部分の一部として左右上方の両端部に互いに平行に位置する一対の固定バーと、これらの固定バーによって揺動チェーンを介して支持される揺動部分と、この揺動部分の一部として左右両端部に互いに平行に位置し、前記揺動チェーンに支持される一対の揺動バーと、これら一対の揺動バーの間に略水平方向へ張り渡されサンゴの小片が取付けられる養殖チェーンと、を有することを特徴とする揺りかご式サンゴ人工養殖架台である。   The second invention is a base part fixed to the seabed, a pair of fixed bars positioned parallel to each other at both the left and right upper ends as a part of the base part, and supported by the fixed bars via a swinging chain. And a pair of oscillating bars that are positioned parallel to both left and right ends as a part of the oscillating part and supported by the oscillating chain, and between the pair of oscillating bars. A cradle-type coral artificial culture stand characterized by having a culture chain stretched horizontally and to which a small piece of coral is attached.

第三発明は、さらに、前記架台部分は、複数本のパイプが組み合わされて構成され、前記一対の固定バーが位置する左右上方の両端部がもっとも高く、中央は低く構成されることを特徴とする揺りかご式サンゴ人工養殖架台である。   The third aspect of the present invention is further characterized in that the pedestal portion is configured by combining a plurality of pipes, the upper left and right ends where the pair of fixing bars are located are the highest, and the center is configured lower. It is a cradle-type coral artificial farm.

第一、又は第二発明によれば、海底に固定される架台部分によって、揺動部分の養殖チェーンは略水平方向へ張り渡されるので、海の浅い場所に設置できる。また、波の動きにより揺動部分が揺動するので、泥土の付着が防止され、取り付いたオニヒトデも振り落とされ易い。また、オニヒトデは揺動部に取り付くには、揺動チェーンを渡らなければならず、取り付きにくい。よって、オニヒトデの食害も防止できる。   According to the first or second invention, the aquaculture chain of the swinging portion is stretched in a substantially horizontal direction by the gantry portion fixed to the seabed, so that it can be installed in a shallow place in the sea. In addition, since the rocking part is swung by the movement of the wave, the mud is prevented from adhering and the attached starfish is easily shaken off. In addition, in order to attach the tiger starfish to the oscillating portion, it is necessary to cross the oscillating chain, which makes it difficult to attach. Therefore, it is possible to prevent the damage of the sea urchin starfish.

第二、又は第三発明によれば、さらに、簡素な構造によって装置を得ることができ、製造コストを抑えることができる。   According to the second or third invention, the device can be obtained with a simple structure, and the manufacturing cost can be reduced.

（Ａ）は、この発明の一実施形態を示す揺りかご式サンゴ人工養殖架台の全体斜視図、（Ｂ）は、（Ａ）のサンゴ小片の取付部分の拡大図である。(A) is the whole perspective view of the cradle type coral artificial culture stand which shows one Embodiment of this invention, (B) is an enlarged view of the attachment part of the coral piece of (A).

この発明の実施形態に係る揺りかご式サンゴ人工養殖架台を、図１（Ａ）に示す。
この揺りかご式サンゴ人工養殖架台１は、海底に固定される架台部分３と、この架台部分３によって揺動チェーン５を介して揺動可能に支持される揺動部分７と、を有する。
揺動部分７は、左右両端部に一対の揺動バー９が設けられ、互いに平行に位置する。これら一対の揺動バー９の間に、略水平方向へ５本（状況により増減）の養殖チェーン１１が張り渡される。５本（状況により増減）の養殖チェーン１１の各中央は、揺動バー９に並行に設けられるぶつかり防止バー１３に連結され、各養殖チェーン１１が互いにぶつかるのを防止する。 A cradle-type coral artificial culture rack according to an embodiment of the present invention is shown in FIG.
The cradle-type coral artificial culture gantry 1 includes a gantry portion 3 that is fixed to the seabed, and a swing portion 7 that is swingably supported by the cradle portion 3 via a swing chain 5.
The swinging portion 7 is provided with a pair of swinging bars 9 at both left and right ends, and is positioned parallel to each other. Between these pair of swing bars 9, five (increase or decrease depending on the situation) aquaculture chains 11 are stretched in a substantially horizontal direction. Each center of the five (increase or decrease depending on the situation) aquaculture chains 11 is connected to a collision prevention bar 13 provided in parallel with the swinging bar 9 to prevent the aquaculture chains 11 from colliding with each other.

これら養殖チェーン１１に、サンゴの小片１５が取付けられる。同図（Ｂ）に示すように、この取付は、なまし線１７によって行なわれる。なまし線１７は、全体が略Ｌ字状を有し、略Ｌ字の縦辺１９の上端が折り返されて深いフック２１となり、養殖チェーン１１に係止される。略Ｌ字の横辺２３は傾斜し、その上端はさらに水平に屈曲し、その水平部分２５にサンゴの小片１５が取付けられる。   Coral pieces 15 are attached to these aquaculture chains 11. As shown in FIG. 5B, this attachment is performed by an annealing line 17. The annealing line 17 has a substantially L shape as a whole, and the upper end of the substantially L-shaped vertical side 19 is folded back to form a deep hook 21 and is locked to the aquaculture chain 11. The substantially L-shaped lateral side 23 is inclined, its upper end is further bent horizontally, and a coral piece 15 is attached to the horizontal portion 25.

架台部分３は、複数本のパイプ（２７〜３５）が組み合わされて構成され、前記一対の固定バー３５が位置する左右上方の両端部がもっとも高く、中央は低く構成される。
すなわち、海底に前後に一対の基礎パイプ２７が互いに平行に配置され、その間を４本の横行パイプ２９が配置され、これらが互いに連結される。各基礎パイプ２７からは上方へ２種類４本の上下パイプ３１が連結される。上下パイプ３１は、各基礎パイプ２７の両端のものは高く、中央よりのものは低い。これら高低の組の上下パイプ３１の先端に、斜行パイプ３３が連結される。よって、合計４本の斜行パイプ３３が設けられる。これら斜行パイプ３３の高い先端に連結して、横行パイプ２９と並行に、固定バー３５が設けられる。 The gantry portion 3 is configured by combining a plurality of pipes (27 to 35), and is configured such that the upper left and right ends where the pair of fixing bars 35 are located is the highest and the center is low.
That is, a pair of foundation pipes 27 are arranged in parallel with each other on the sea floor, and four transverse pipes 29 are arranged therebetween, and these are connected to each other. Two types of four upper and lower pipes 31 are connected upward from each foundation pipe 27. The upper and lower pipes 31 are higher at both ends of each foundation pipe 27 and lower than those at the center. A skew pipe 33 is connected to the ends of the upper and lower pipes 31 of the high and low sets. Therefore, a total of four skew pipes 33 are provided. A fixed bar 35 is provided in parallel with the transverse pipe 29 so as to be connected to the high ends of the oblique pipes 33.

この固定バー３５に、揺動チェーン５の一端が連続され、この揺動チェーン５の他端に、揺動部分７の揺動バー９が連続する。揺動チェーン５は、１本の揺動バー９に２本がハの字に設けられ、合計４本設けられる。揺動チェーン５が、揺動部分７の揺動を促進する。
固定バー３５と揺動バー９の両端の間には、長さに余裕がある過揺れ防止チェーン３７が取付けられ、揺れが大きくなりすぎるのを防止する。
なお、揺動部分７の養殖チェーン１１があまり大きく垂れ下がって海底に近づかないように、揺動部分７に複数の小さな浮きを取付けることも可能である。
「実施形態の効果」
海底に固定される架台部分３によって、揺動部分７の養殖チェーン１１は略水平方向へ張り渡されるので、浮力を有する筏や浮きを必要とせず、縦方向へ垂下することもない。よって、海の浅い場所に設置できる。 One end of the swing chain 5 is continuous with the fixed bar 35, and the swing bar 9 of the swing portion 7 is continuous with the other end of the swing chain 5. Two swing chains 5 are provided in the shape of a letter C on one swing bar 9, and a total of four swing chains 5 are provided. The swing chain 5 promotes the swing of the swing portion 7.
Between the both ends of the fixed bar 35 and the swing bar 9, an overswing prevention chain 37 having a sufficient length is attached to prevent the swing from becoming too large.
It is also possible to attach a plurality of small floats to the swinging portion 7 so that the aquaculture chain 11 of the swinging portion 7 hangs down so much that it does not approach the seabed.
"Effect of the embodiment"
The aquaculture chain 11 of the oscillating portion 7 is stretched in a substantially horizontal direction by the gantry portion 3 fixed to the seabed, so that it does not require a buoyant ridge or float and does not hang vertically. Therefore, it can be installed in a shallow place in the sea.

また、揺動チェーン５で支持された揺動部分７が、波の動きにより揺動するので、揺動部分７に取付けられるサンゴの小片１５へ、泥土が付着するのが防止される。また、この揺動により、サンゴの小片１５へ取り付いたオニヒトデも、振り落とされ易い。また、オニヒトデは揺動部のサンゴの小片１５へ取り付くには、揺動チェーン５を渡らなければならず、非常に取り付きにくい。よって、オニヒトデの食害も防止できる。   Further, since the swinging portion 7 supported by the swinging chain 5 swings due to the wave motion, mud is prevented from adhering to the coral pieces 15 attached to the swinging portion 7. Also, the rockfish that is attached to the coral piece 15 is easily shaken off by this swinging. In addition, in order to attach the sea urchin star to the coral piece 15 of the swinging part, it is necessary to cross the swinging chain 5 and it is very difficult to attach. Therefore, it is possible to prevent the damage of the sea urchin starfish.

さらに、パイプ（２７〜３５）とチェーン（５，１１，３７）を用いた簡素な構造によって装置を得ることができ、製造コストを抑えることができる。
また、装置全体を低く横張りにすることで、波浪の影響を軽減できる。
さらに、装置の構成に横張りのチェーンを用いることで、切断を防ぎ、二点（両端）支持により負荷を軽減できる。 Furthermore, the apparatus can be obtained with a simple structure using the pipes (27 to 35) and the chains (5, 11, 37), and the manufacturing cost can be reduced.
Moreover, the influence of a wave can be reduced by making the whole apparatus low and horizontal.
Furthermore, by using a horizontal chain in the configuration of the apparatus, cutting can be prevented and the load can be reduced by supporting two points (both ends).

また、サンゴ片は、なまし線を曲げて針金で取り付けるため、簡易であり単品での移動も容易である。
さらに、チェーンを使用のため切断の心配もなく、底部からサンゴの位置を浮かすことでオニヒトデによる食害からも守られる。よって養殖、増殖の期待とともにそのまま密度の濃いサンゴ群集（産卵する親サンゴ）の維持が期待できる。 Moreover, since the coral piece is bent and attached with a wire, the coral piece is simple and easy to move by itself.
In addition, because of the use of a chain, there is no worry about cutting, and the coral position can be lifted from the bottom so that it can be protected from the damage caused by the starfish. Therefore, it can be expected to maintain a dense coral community (parent coral that lays eggs) as well as expectations for aquaculture and growth.

揺りかご式にすることで、自然の潮流から受ける架台全体の揺れを利用しサンゴに付着する泥土を除去できる。サンゴ上に泥土が付着するとサンゴ自ら粘液を出して、これを除去しようとし、泥土がサンゴの能力を超え堆積すると、ストレス等で生息が阻害されることが知られているが、この生息阻害を防止できる。   By using a cradle type, mud that adheres to coral can be removed using the shaking of the entire gantry from natural tides. It is known that when mud adheres to the coral, the coral itself tries to remove mucus and remove it, and if mud accumulates beyond the capacity of the coral, it is known that the habitat is inhibited by stress etc. Can be prevented.
