藻類生材が用いられている。Propagation materials for seaweed must be suitable for the growth of seaweed spores, etc., and must have a shape and structure suitable for the growth of seafood, as well as be easy to manufacture and install. However, durability is also required for these purposes, and currently concrete structures,
In addition to steel structures, organic materials such as bamboo, wood, Manila hemp, or raw seaweed materials made of synthetic resin fibers assembled into a fence or mesh pattern are used.

という問題を有している。(Problems to be Solved by the Invention) By the way, propagation materials for concrete structures are heavy, and therefore require a great deal of labor and equipment to handle, install, or collect, and are easily damaged by impacts. Concrete has a problem in that after it is dropped into the sea, it remains slightly alkaline for a while due to the lime it contains, making it slow for seaweeds to settle on it.

表面が剥離浮遊するなど耐久性に欠けるという問題を有
している。Similar to concrete structures, growth material for steel structures is heavy and requires a great deal of labor and equipment to handle, install, and collect, and the steel also oxidizes and elutes, and the surface peels and floats. It has the problem of lacking durability.
また有機性材料や合成樹脂繊維体は、何れも使用中に徐
々に海中に溶出するなど何れも耐久性に問題がある。Furthermore, organic materials and synthetic resin fibers all have problems with durability, such as gradual elution into the sea during use.
本発明は上記問題点に鑑みなされたもので、耐久性を有
しかつ海藻の着床養殖に適した海藻類生材を提供する。The present invention was made in view of the above-mentioned problems, and provides raw seaweed material that is durable and suitable for the cultivation of seaweeds.
本発明は、純チタン、チタン合金またはチタンめっき材
（以下これをチタン材料と略称する）を網目状に加工し
た多孔体からなる海藻類生材である。The present invention is a raw seaweed material made of a porous body obtained by processing pure titanium, a titanium alloy, or a titanium-plated material (hereinafter referred to as titanium material) into a mesh shape.
チタンは海水、酸アルカリに対して不変的な耐食性が高

同等以上の引張り強さを有している。従って板材、管材
、線材などに加工して使用されている。Titanium has high corrosion resistance against seawater and acids and alkalis, has a very low corrosion potential in seawater (in running water), is the second most stable metal in an aqueous solution after platinum, and has a specific gravity of 4. It is lighter than other metals at .51, has a Young's modulus of 172 compared to steel, and has flexibility, and has tensile strength equal to or higher than mild steel. Therefore, it is used by processing it into plates, pipes, wires, etc.

、またチタン材料が腐食により消滅することなく、潮流
、波浪など外力に抗する強度を有しているので、長期に
亘り安定した海藻の養殖をおこなうことができる。Since the wood planting material is composed of a porous body made of titanium material processed into a mesh shape, solutions and harmful metal ions will not be leached from the installed vegetation material, and since it is a porous material, it will not stagnate. A fresh seawater flow is always supplied without any problems. Therefore, it is easy for spores and seaweed to settle, and the titanium material does not disappear due to corrosion and has the strength to withstand external forces such as tides and waves, so seaweed can be cultivated stably over a long period of time. Can be done.

とができる。Titanium has good workability and can be processed and assembled into porous bodies of various shapes suitable for growing algae, seafood, and collection, and because it is lightweight, it is easy to manufacture, transport, install, and collect on land. Because of its good durability, this vegetation material can be used to economically and selectively construct seaweed reefs suitable for the characteristics of sea areas and seabed bases, as well as for aquaculture.

Inside the net 32 fixed in place by 3,
Supports 34 are provided as appropriate to form the net 32 into a hilly shape, and planar vegetation materials 35 are attached at regular intervals to the surface of the net by braiding thin strings made of titanium material to have a predetermined area. It is constructed. The seaweed reef 31 configured in this way generates an appropriate upwelling current without interfering with the seawater flow, and since the surface of the vegetation material 35 has a braided rough surface, the settling force of the seaweed is reduced. Once implanted, the roots will dig into the strands and will not easily peel off. Furthermore, by installing the vegetation materials 35 at intervals, seaweed does not grow densely, which is suitable for growing seaweed.
これらの海藻礁は何れも海中や海底において、海域の性
状や海水流の方向等を考慮して設置される。All of these seaweed reefs are installed in the sea or on the seabed, taking into account the characteristics of the sea area, the direction of seawater current, etc.

果的におこなうことができる。(Effects of the Invention) As explained above, the present invention is a raw seaweed material made by processing titanium material into a mesh shape, so the seaweed reef constructed using this material is rich in corrosion-resistant organisms and free from harmful ions. Since it does not elute seaweed and does not obstruct seawater flow, it is easy for spores and seaweed to settle, making it possible to cultivate seaweed stably over a long period of time. It is possible to effectively gather, spawn, and grow the fish and shellfish you eat.

Because it is easy to install, it is not only possible to install it in a location suitable for sea area conditions and aquaculture, but also to move it to sandy areas. It can also be effectively used as a purification measure for Akashio.
