SOLUTION: This is a method of multiplying corals 3, in which iron or a material containing iron is hammered into the seabed 1 or is adhered or weighted with a stone or the like and fixed. Specifically, as the iron or iron-containing material, nails, male screws, bolts, reinforcing bars, iron piles or iron wire nets are used and driven into the seabed 1 or screwed or bonded to rocks or bedrock of the seabed 1. Fix with stones or stones or rocks. If the coral 3 is easily attracted by exposing the iron part of the above material, the coral 3 can surely propagate. To expose the iron part, grind it with a grinder, scratch it with a blade, or make a score with a gold saw. It is also possible to construct artificial fishing reefs by submerging an iron three-dimensional structure on the seabed. [Selection diagram] Figure 1
Description
本発明は、簡便確実な方法でサンゴを増殖する方法に関する。 The present invention relates to a method for multiplying corals by a simple and reliable method.
従来のサンゴ増殖法としては、イケス等で人工的に育成した幼サンゴを海底の岩などに固定して移植し、移植後の幼サンゴを生育させサンゴ礁の形成を期待するものであった。そのため、従来のサンゴ増殖法では、幼サンゴの育成や育成した幼サンゴの移植場所までの生きたままの輸送など多大な費用を必要とする。また、移植したサンゴが死亡することがよくある。 As a conventional coral breeding method, a young coral artificially grown by IKES or the like was fixed to a rock on the seabed and transplanted, and the young coral after the transplant was grown to expect formation of a coral reef. Therefore, the conventional coral breeding method requires a great deal of cost, such as raising young corals and transporting the raised young corals to the transplantation site as they are. Also, transplanted corals often die.
これに対し、特許文献1のように、サンゴ礁海域に適した魚類増産効果の高い漁礁を開発するために、サンゴ礁海域に適した人工漁礁であり、立体構造を形成する平面の開口部や内部等に鋼製、樹脂製、または化学繊維製の網を有するようにし、この網に造礁性サンゴを針金等で同定して人工漁礁の一部とする構成が開示されている。 On the other hand, as in Patent Document 1, in order to develop a fish reef suitable for coral reef sea areas and having a high effect of increasing fish production, it is an artificial fishing reef suitable for coral reef sea areas, such as a planar opening or the inside that forms a three-dimensional structure. Discloses a structure in which a net made of steel, resin, or chemical fiber is provided, and a reef-building coral is identified in this net by a wire or the like to be a part of an artificial fishing reef.
しかしながら、特許文献1のように、鋼製の網を用いる構成は開示されているが、この鋼製の網を利用してサンゴを増殖できるという説明は全く無い。恐らく、鋼製でも海水で錆びにくいように亜鉛メッキしたりステンレスを使用しているからでしょう。 However, although a configuration using a steel net as disclosed in Patent Document 1 is disclosed, there is no description that corals can be propagated using this steel net. Probably because even if it is made of steel, it is galvanized or stainless steel is used to prevent it from rusting in seawater.
本発明は、海底でのモズク養殖においてモズクの種付けを施した網等を海底に固定する目的で使用される海底に打ち込まれた多くの鉄筋に小規模なサンゴ礁が自然に形成されることに着目し発展させたものである。この鉄筋に形成した小規模サンゴ礁の周辺の岩などには、ほとんどサンゴが確認できないという偶然な気付きから、鉄筋の材料である鉄(Fe)に何らかのサンゴの卵や幼生を誘引する働きが有るものと推測している。
本発明の技術的課題は、このような問題に着目し、鉄筋などの鉄材を海底に打ち込むなどして海底に固定すると、サンゴが誘引されて増殖できることにある。
INDUSTRIAL APPLICABILITY The present invention focuses on the natural formation of small-scale coral reefs on many rebars driven into the seabed used for the purpose of fixing nets etc. seeded with Mozuku in the seabed in the seabed mozuku culture. It has been developed. There is a function of attracting some coral eggs and larvae to iron (Fe), which is the material of the reinforcing bar, because it is a coincidence that almost no coral can be confirmed in the rocks around the small coral reef formed in this reinforcing bar. I'm guessing.
The technical problem of the present invention is to pay attention to such a problem, and when an iron material such as a reinforcing bar is driven into the seabed and fixed to the seabed, the coral can be attracted and proliferate.
本発明の技術的課題は次のような手段によって解決される。
請求項1は、鉄又は鉄を含む素材を用意して、その本体の表面の少なくとも1部において鉄部を露出させる加工を行い、前記の素材を海底に打ち込むか又は接着し又は石などで重しをして固定し、その鉄部が露出された前記表面によってサンゴを誘引して、前記の素材に前記サンゴを直接付着させることを特徴とするサンゴの増殖方法である。
The technical problem of the present invention is solved by the following means.
According to claim 1, iron or a material containing iron is prepared, and at least a part of the surface of the main body is subjected to a processing for exposing the iron portion, and the material is driven into the seabed or is adhered or heavy with a stone or the like. It is a coral breeding method, characterized in that the coral is attracted by the surface having the iron portion exposed, and the coral is directly attached to the raw material .
請求項2は、前記の鉄又は鉄を含む素材として、釘、雄ネジ、ボルト、鉄筋、鉄杭又は鉄製の金網を用い、海底に沈め若しくは打ち込むか又は海底の岩や岩盤に螺入又は接着し又は石や岩で重しをして固定することを特徴とする請求項1に記載のサンゴの増殖方法である。
請求項1のように、鉄又は鉄を含む素材を海底に打ち込むか又は接着し又は石や岩で重しをして固定するので、素材が流されることはなく一定の位置に停滞し、鉄の成分でサンゴの卵や幼生が誘引され、サンゴが増殖しサンゴ礁となる。しかも、本発明のサンゴ増殖法では、従来のような複雑な工程は必要としない。また、請求項1のように、前記素材を研磨や傷付けで鉄部を露出させてサンゴが誘引され易くするので、サンゴの受精卵や幼生が露出した鉄部に誘引され、確実にかつ効果的に誘引されて増殖する。
As in claim 1, since iron or a material containing iron is driven into the seabed or is fixed or fixed by weighting with stones or rocks, the material is not washed away and stays at a certain position, and The coral eggs and larvae are attracted by the ingredients of, and the corals multiply and become coral reefs. Moreover, the coral breeding method of the present invention does not require a complicated process as in the past. Further, as in claim 1, since the coral is easily attracted by exposing the iron part by polishing or scratching the material, fertilized eggs and larvae of the coral are attracted to the exposed iron part, and reliably and effectively. Are attracted to and multiply.
請求項2のように、前記の鉄又は鉄を含む素材として、釘、雄ネジ、ボルト、鉄筋、鉄杭又は鉄製の金網を用い、海底に沈め若しくは打ち込むか又は海底の岩や岩盤に螺入し又は接着し又は石や岩で重しをして固定するので、通常の市販品で容易に実現でき、安価に確実に実現できる。
As in
次に本発明によるサンゴの増殖方法が実際上どのように具体化されるか実施形態を説明する。図1は本発明によるサンゴ増殖方法の第1実施例を示す正面図である。図1のように、海底1に釘や鉄筋や鉄杭等の鉄棒2を打ち込んで固定してある。前記鉄棒2の上端2eは、切断や研磨の際に鉄部が露出している。時間が経つにつれてサンゴの卵や幼生が鉄部に誘引されて成長し、図1のように、鉄棒2の上端2eに多数のサンゴ3…が成育している。
Next, an embodiment will be described as to how the method for multiplying corals according to the present invention is actually embodied. FIG. 1 is a front view showing a first embodiment of a coral breeding method according to the present invention. As shown in FIG. 1, nails, reinforcing bars,
図1は一例であるが、図2のように、海底1に固定された鉄棒2の上端3eの切断部を露出させると共に上端寄りの側面2sをグラインダー等で研磨し鉄部を露出させるとサンゴの卵や幼生が誘引されて成長しサンゴ3、3となる。鉄棒3の側面を研磨したり研削し又は鉄鋸やタガネなどで場所を選択して傷付けたりして鉄部を露出させると、鉄棒2の好みの側面2sにもサンゴ3…が付着し成長する。
Although FIG. 1 is an example, as shown in FIG. 2, when the cut portion of the upper end 3e of the
鉄棒3の側面の傷を複数箇所に付けて鉄部を露出させると、図3のように、鉄棒2の側面2sの複数箇所にサンゴ3…を付着・成長させることもできる。従って、鉄棒2の側面2sのサンゴ3…の付着・成長する場所を選択して、サンゴが付着・成長する場所を制御することで美しく仕上げ、水槽の中であれば、観賞用とすることもできる。なお、付近のサンゴが鉄棒2の側面2sに付着して成長することもある。
When the side surface of the
海底に固定する鉄素材として、鉄の切断や切削で生じた鉄粉や削りカスをセメントや石膏に混合して硬化させたものを海底に固定する方法もある。特に鉄粉や削りカスは鉄筋の切断面同様に鉄部がよく露出しているので、サンゴを誘引しやすい。また鉄粉や削りカスを接着剤に練り込み、海底の岩などに直接付着させ硬化させ固定すれば、同様の効果が期待できる。 As an iron material fixed to the seabed, there is also a method of fixing iron powder or shavings generated by cutting or cutting iron to cement or gypsum and hardening the mixture to the seabed. Especially in iron powder and shavings, the iron part is well exposed like the cut surface of the reinforcing bar, so it is easy to attract coral. The same effect can be expected if iron powder or shavings are kneaded into an adhesive agent and directly adhered to rocks on the seabed to be hardened and fixed.
毎年5〜6月の満月の夜にサンゴが産卵するが、受精した卵や幼生が鉄に誘引されるように鉄製の金網を海面付近に浮かべておき、しばらくしてから海底に沈める手法も可能である。なお、金網を海面に浮かべるには、発泡スチロール製の浮体や浮きを縛っておき、海底に沈める時点で切り離せばよく、サンゴの群体を形成でき、白化現象により死滅したサンゴ群の再生が期待できる。前記金網は、鉄部を露出させるべく、コンクリート面の上で表側も裏側も引きずって各所に傷を付けるのが好ましい。 Coral spawns on a full moon night every May to June, but it is also possible to float an iron wire net near the surface of the sea so that fertilized eggs and larvae are attracted to the iron and sink it to the seabed after a while. Is. In order to float the wire net on the surface of the sea, a floating body made of styrofoam or a floating body may be tied up and separated at the time of sinking to the sea bottom, so that a coral colony can be formed and the coral colony that has died due to the whitening phenomenon can be expected to be regenerated. In order to expose the iron part, it is preferable that the wire mesh is scratched on the concrete surface by dragging both the front side and the back side.
以上のように、サンゴの卵や幼生の居そうな海域で海水を汲み上げた水槽またはサンゴを飼育している水槽に鉄製の材料や鉄を含んだ素材を入れておき、鉄の成分にサンゴが誘引され付着して成長するので、容易にかつ確実にサンゴを増殖でき、本来法律で採集が禁止されている天然のサンゴを採集することなく観賞用などにも利用することができる。 As described above, iron material or iron-containing material is placed in the aquarium pumping seawater or the aquarium breeding coral in the area where coral eggs and larvae are likely to live, and coral is added to the iron component. Since it attracts and attaches and grows, corals can be easily and surely propagated, and it can be used for ornamental purposes without collecting natural corals, which are originally prohibited by law.
