Field of Industrial Application The present invention relates to an algal spore bed that is submerged in the sea to ensure that algal spores are deposited thereon. With one rational configuration, it is possible to provide an effective algae spore bed that supports the growth of algae, harvests the grown algae, attracts fish and shellfish for the algae, and develops the basis for creating new fishing grounds. be.

穫が著しく減少し、国や地方自治体は勿論、水産試験場
や漁業組合等でも新たな漁場の開発が進められている。BACKGROUND OF THE INVENTION Due to the deterioration of the natural environment, the harvest of marine marine products along the coasts of Japan has significantly decreased, and not only the national and local governments, but also fisheries research institutes and fishermen's cooperatives are developing new fishing grounds.

ックを胞子床に見立て、それに藻類の胞子を撚り込んだ
種糸やロープを巻き付ける方法が専ら採用されていた。Conventionally, artificial reefs were created by sinking earth and stones, abandoned ships, concrete blocks, etc. into the sea to provide homes for fish. However, when it came to growing algae, the method used was to use a concrete block as a spore bed and wrap around it seed yarn or rope with algae spores twisted around it.

However, the algae do not have enough growth, so there are few fish, shellfish, and microorganisms that gather for the algae and use the algae as homes and food. is also limited by it.

まう。The reason for the poor growth of algae is that the concrete block that serves as the spore bed exudes an extremely strong alkaline component, and the entire block is surrounded by a layer of alkaline water, which traps the small-sized spores. This is also because even if they germinate, they do not take root well and are easily washed away by currents. Therefore, even if you can plant spores of spores such as arame, wakame, and kelp in the spore bed, the concrete blocks will not allow you to wait until they have fully grown, and you will not be able to use the spore beds to grow the highly viable green algae. (Azaisu, Hitoegusa, etc.)
It will be monopolized by creatures with strong breeding power such as Fujibbo and Fujibbo.

とにある。2. Means for Solving the Problems The present invention eliminates the leaching of alkaline components and directly implants spores, which improves the rooting ability compared to spore seed yarn, thereby helping the growth of algae, thereby allowing the desired algae to grow. It is possible to grow reliably, and its composition consists of kneading cement powder, foamable resin, aggregate, and hardening agent, and assimilating this into a lump of the desired shape and size. be.

面にも発泡による微細な壷状凹部が形成される。E. Effect: When the cement powder mixed with the foamable resin is mixed with a hardening agent and kneaded, the foamable resin foams and envelops the cement powder, and numerous fine pot-shaped recesses are formed on the surface. In the mixture mentioned above, in which stones and sand are mixed excessively as aggregates, fine pot-shaped recesses are formed on the inner surface of the gaps (cavities) created between the aggregates due to foaming.

激減するのである。Such a raised structure with a series of gaps between aggregates increases water permeability and allows spores to adhere, making it easier for water containing spores to drain when scooped up, and increasing the surface area per volume. The adhesion area of spores increases greatly, and the spore implantation property is dramatically improved due to the rough surface effect enhanced by the pot-shaped recesses. Moreover, due to the action of the foaming resin, the alkaline components peculiar to cement are sealed and do not leach out, so the rate of death of spores due to the alkaline components after the 7i bed is drastically reduced.

A concrete admixture in which polymethylene, polyphenyl, isocyanate, tridene, diisocyanate) are mixed in a ratio of 1 to 1, and an excess of stone and sand is mixed in as aggregate, and calcium chloride is the main component as a hardening agent. Add 1% aqueous solution to them and knead. Then, this is made into a lump of about 15 cm x 30 cm x 5 cm, and the reinforcing bars 1a are buried with both ends protruding and waited for solidification.

are strongly and densely bonded by the adhesive force of the resin and the chemical reaction between the concrete admixture and cement. The interior of the algae spore bed 1 is caused by the gaps between the aggregates 3.
Not only does it have a water-permeable structure, but it also dramatically increases the area on which spores can land. In addition, the surface has a rough shape with an open cell structure in which four pot-shaped parts are connected, making it easier for spores to settle.

床４の表面に点在させて氷中へ沈設する。This algae spore bed 1 may be deposited directly into the sea or attached integrally to the surface of another structure, but as shown in Figure 3, an artificial reef consisting of multiple layers (hereinafter referred to as a multi-layer structure bed) may be used. ) 4 and can be used as a part of the multilayer structure floor 4. This will not only prevent even a small algae spore bed from being washed away and dispersed by the current, but also
When the algae spore bed ages, it is effective to replace it to refresh the entire multilayer structure bed. The material of the multilayer structure floor 4 is not particularly limited, but it must have sufficient size, weight, and strength, and for example, a concrete structure with internal reinforcing bars or iron material is used. The base 4a, which is the lowest layer, is made of steel and reinforced concrete to provide sufficient strength. In order to increase adhesive strength and prevent the outflow of strong alkaline components, concrete mixed with a concrete N additive containing calcium chloride as a main component is formed into a raised shape, and reinforcing bars 5a are further erected at appropriate locations on the surface. A four-hole recess 5 is formed. For installation, the algae spore bed 1 of the present invention is fixed at 1/1 by tying reinforcing bars together with wire, etc., and the algae spore bed 1 is dotted on the surface of the multilayer structure floor 4. and submerge it in ice.

This is thought to be due to some chemical interaction between the Portland cement and the incyanate-terminated prepolymer, or because the seven-mention powder was coated with a foamable resin.

種の成分が浸出されていると思われる。Next, to illustrate the experimental results of the algal spore bed according to the present invention,
In an experiment to propagate Arame, which was previously thought to be impossible to artificially cultivate, germination was observed three months after spores were implanted, and the growth continued steadily thereafter, allowing fish, planers, and fish that had not been observed in the surrounding area before the start of the experiment to grow. Creatures such as shellfish, sea galls, and shrimp gathered there, giving us confidence that the prospects are bright not only for algae cultivation but also for the harvest of fish and shellfish. Also, from the results of algae growth,
It was observed that the growth speed was faster and more abundant than in the natural state, and this suggests that not only are alkaline components not leached from the algae spore bed 1, but rather certain components that are effective as fertilizers for brown algae are leached out. Seem.

例に限定するものではない。In the present invention, an aqueous solution of a calcium chloride concrete admixture is used as a hardening agent in the above embodiments, but the amount of this admixture can be reduced or water can be used as necessary. In addition to stones and sand, aggregates include glass, metals, and artificial stones such as bricks and ceramics, and foamable resins include prepolymers with terminal incyanate groups (polymethylene, polyphenyl, isocyanate toridene di-incyanate). 6. In addition, the old reinforcing bars are buried as necessary, and the old reinforcing bars are buried in the same manner as 1.

きい。G. Effects According to the present invention, the surface of the algal spore bed has fine irregularities, and the surface of the internal gap has a similar structure, so that the algae spores have a good settling property, and the algae that have grown to Y1 have a strong squirt. 6. Root breakage does not occur and the rate of floating algae is low. In addition, since the entire algal spore bed is kept neutral, the germination rate is high, and growth is also good due to some factor (possibly fertilizer) that helps the growth of algae. This allows artificial cultivation by forcing the spores of the desired algae to settle on the surface of the tank, whether the bottom is sandy or the concrete surface of an aquaculture tank. If the desired algae are grown on the coast through artificial aquaculture, a variety of living things will gather there, and the hope is that fish and shellfish will be harvested.
