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 material.
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）の先着、又はそれらの死骸の堆積
等により有用海藻の着床場が荒れて極めて貧海藻
地帯となつた所謂磯焼けの沿岸海域がある。 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.
Due to the feeding damage of abalone, etc., the first arrival of knotted or knotless calcareous algae (coral algae), or the accumulation of their carcasses, the landing place for useful seaweed has become rough, resulting in an extremely poor seaweed area. There are coastal waters.
本発明の目的は、これらの沿岸海域に海藻が繁
茂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 where seaweed flourishes in these coastal waters.
本発明は、金属粒子及び鉱物粒子を含有する熱
可塑性樹脂の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 comprising a porous body of thermoplastic resin containing metal particles and mineral particles.
本発明の海藻殖生材は、連続孔及び又は独立孔
を有し孔内に海水の作用により腐食・発錆・崩壊

で、海藻の胞子又は配偶体を含む液中で吸着又は
サクシヨンにより簡単に胞子又は配偶体を孔内に
着床せしめることができ、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/or independent pores, and contains metal and/or mineral powder particles that corrode, rust, and disintegrate due to the action of seawater, so seaweed spores and Spores or gametophytes can be easily implanted in holes by adsorption or suction in a fluid containing gametophytes, which are then fixed to rocks, gravel, artificially constructed frames, fish reefs, etc., and then sunk to the seabed. This promotes the germination and growth of seaweed spores, allowing the seaweed to take root on rocks, gravel, fish reefs, construction frames, etc. on the ocean floor. 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.
金属及び又は鉱物としては、鉄、アルミニウ
ム、その鉱石、鉱滓、スラツグ等があげられる。 Examples of metals and/or minerals include iron, aluminum, their ores, slag, and slag.
これらは熱可塑性樹脂との混合物として使用す
ることができる。 These can be used as a mixture with thermoplastic resins.
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。 As the porous body of the present invention, it is sufficient that spores or gametophytes with a size of 5 to 50 μ can enter and implant therein, so any porous body having pores of a larger size than this is sufficient.
このような多孔体の製造法の一例としては、該
金属及び又は鉱物の粉粒体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、一定期間後に金属・鉱物粒
子の腐食と共に崩壊・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
せしめても良い。 An example of a method for manufacturing such a porous body is to mix the metal and/or mineral powder and thermoplastic resin particles, mold the mixture, and then heat it to around the melting point of the resin to form a sintered body. preferable. This material is extremely advantageous because it forms a castella-like solid, has suitable connecting pores, allows easy attachment of spores, and disintegrates and disappears with the corrosion of metal/mineral particles after a certain period of time. Alternatively, a foam may be obtained by using a relatively large amount of resin and impregnating resin particles with a foaming agent, or may be foamed by blowing air or other gas.
この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。海藻による光の吸収効率を低下
せしめないからである。 This porous material 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.
又、本発明の殖生材の製造に当たり予め尿素及
び沃度塩等の栄養塩を少量含浸させておくと、目
的とする海藻の成長促進に役立つ。 In addition, when producing the propagation material of the present invention, impregnating it with a small amount of nutritional salts such as urea and iodide salt in advance will help promote the growth of the desired seaweed.

に根を下ろし、多孔体は崩壊・消滅した。 An example of an embodiment of the present invention is to thoroughly mix iron powder pulverized to about 30μ, 20 parts of normally generated lathe waste that has been thoroughly washed and removed, and 80 parts of medium-low pressure polyethylene powder. The plate was placed in a flat press mold and heated and sintered to form a plate with a thickness of 3 mm.The plate was then implanted with spores of snails that had been artificially cultured in a culture tank, and the plate was made into a plate with a size of approximately 20 x 20 mm. They were cut into small pieces and nailed to a rocky area at a depth of around 2 meters in the ocean, completely free of seaweed, at a density of 3 pieces per square meter. After that, the spores germinated, the Kajime grew and took root in the rock, and the porous body collapsed and disappeared.
