Description
【発明の詳細な説明】 本発明は海藻殖生材に関するものである。[Detailed description of the invention] The present invention relates to seaweed propagation materials.
海岸には、海藻の繁殖に適さない砂地の海岸が
あり、又かつては海藻が繁殖していたが、ウニ、
アワビ等の食害により、又は有節又は無節の石灰
藻（サンゴ藻）の死骸の堆積等により海藻が絶滅
した又は絶滅に瀕している所謂磯焼けの海岸があ
る。 There are sandy beaches on the coast that are not suitable for seaweed to grow, and seaweed used to grow there, but sea urchins, seaweed, etc.
There are so-called rocky beaches where seaweed has become extinct or on the verge of extinction due to damage from abalone, etc., or due to the accumulation of carcasses of knotted or knotless calcareous algae (coral algae).
本発明の目的は、これらの海岸に海藻が繁殖す
る藻場を形成させる為の海藻殖生材を提供するこ
とである。 An object of the present invention is to provide seaweed propagation materials for forming seaweed beds on these beaches.
本発明は、腐食性有機物を内蔵する熱可塑性樹
脂の連続多孔体からなる海藻殖生材に関するもの
である。 The present invention relates to a seaweed propagation material consisting of a continuous porous body of thermoplastic resin containing corrosive organic matter.

これを岩、礫、或いは人工構築のフレーム、魚礁
等に固設せしめて海底に沈めることにより、海藻
胞子の発芽、生育を促し、海藻が海底の岩石、
礫、魚礁、構築フレーム等に根を下ろすことがで
きる。しかも、一定の期間の経過後に崩壊・消滅
せしめることも容易であり、好都合である。 The seaweed propagation material of the present invention has continuous pores and contains corrosive organic matter in the pores, so spores or gametophytes can be easily transferred into the pores by suction in a liquid containing seaweed spores or gametophytes. It is possible to induce implantation,
By fixing this to rocks, gravel, artificial frames, fish reefs, etc. and sinking it to the seabed, the germination and growth of seaweed spores will be promoted, and the seaweed will grow into rocks on the seafloor,
It can take root in gravel, reefs, construction frames, etc. Moreover, it is convenient because it is easy to collapse and disappear after a certain period of time has elapsed.
以下、本発明について詳細に説明する。 The present invention will be explained in detail below.
腐食性有機物としては、例えば木粉、結晶性セ
ルロース等が挙げられる。これらは通常は粒状で
使用されるが、これに限定されない。 Examples of corrosive organic substances include wood flour and crystalline cellulose. These are usually used in granular form, but are not limited to this.
熱可塑性樹脂としては、例えばポリエチレン、
ポリプロピレン等のポリオレフインその他が挙げ
られる。 Examples of thermoplastic resins include polyethylene,
Examples include polyolefins such as polypropylene and others.
本発明の連続多孔体としては、大きさ５〜50μ
の胞子又は配偶体が入り込み着床すればよいの
で、これ以上の大きさの孔を有するものであれば
よい。 The continuous porous body of the present invention has a size of 5 to 50 μm.
It is sufficient that spores or gametophytes enter the hole and implant therein, so it is sufficient that the hole has a hole larger than this size.
このような多孔体の製造法としては、腐食性有
機物粒子と熱可塑性樹脂粒子を混合して成形した
後、樹脂の融点付近に加熱して焼結体とするのが
好ましい。このものはカステラ状の固体となり、
適当な連結孔を有し胞子の着床が容易であり、か
つ、一定期間後に崩壊・消滅するので、極めて好
都合である。又樹脂量を比較的多くして樹脂粒子
に発泡剤を含浸せしめたものを使用して発泡体と
しても良く、又空気その他のガスを吹き込んで発
泡体としても良い。 As a method for manufacturing such a porous body, it is preferable to mix corrosive organic particles and thermoplastic resin particles, mold the mixture, and then heat the mixture to around the melting point of the resin to form a sintered body. This substance becomes a castella-like solid,
It is extremely advantageous because it has suitable connecting pores, allows easy attachment of spores, and disintegrates and disappears after a certain period of time. Further, a foam may be obtained by using a relatively large amount of resin and impregnating resin particles with a foaming agent, or a foam may be obtained by blowing air or other gas.
この連続多孔体は黒色や濃色の光を吸収しやす
い物より白色や明色の光を反射するもの又は透す
ものであるのが良い。海藻による光吸収効率を低
下せしめないからである。 This continuous porous body is preferably one that reflects or transmits white or light colored light rather than one that easily absorbs black or dark colored light. This is because it does not reduce the light absorption efficiency of seaweed.

~60% by weight, a mixture of 80-40% by weight of polyethylene fine particles, or a mixture of 20-70% by weight of crystalline cellulose and 80-30% by weight of polyethylene fine particles is placed in a mold to form a cylindrical shape with a small hole in the center. After compression molding, a solid porous body was obtained by heating and sintering. This cylinder was cut horizontally to obtain a disc-shaped porous body measuring 10 mmφ×200 mm. This material, on which wakame spores were implanted, was fixed by inserting a stud 3 into the small hole 2 at the center of the porous material 1 and nailing it to a rock 4, as shown in FIG. After that, the spores germinated, wakame seaweed grew and took root in the rock, and the porous body collapsed and disappeared.
本発明の海藻殖生材の形状は特に規定されない
が、例えば第１図に示したような円板形の他角板
でもよく、板チヨコのように割目を入れた物を分
割して用いてもよく、いずれの形状でもよい。 The shape of the seaweed propagation material of the present invention is not particularly limited, but it may be a disk-shaped diagonal plate as shown in Fig. 1, or it may be used by dividing a plate with cracks like a horizontal plate. It can be of any shape.
