Description

  The present invention is a resource utilization technology and business system for coastal seaweed that uses the food property of earthworm earthworms that can safely process a large amount of seafloor seaweed that has a large adverse effect on the beach environment, safely, pollution-free, and inexpensively.

Many seaweeds launched on Japanese beaches with a long coastline obstruct the aesthetics of the beaches, and the bad smell caused by seaweed rot has an adverse effect on the local environment, increasing the burden on beach management. At present, the treatment of drifting seaweed is carried out by sandy beach disposal, but not only has it reached the limit in any region, but the temporary disposal of massive drifting seaweed is anaerobic. Hydrogen sulfide harmful to living organisms is generated by the decomposition process. Incineration also requires significant energy and expense. Furthermore, a treatment method for producing compost or feed by fermentation treatment with organic microorganisms has been proposed. However, it is difficult to manage microorganisms, and the maintenance cost is high, which is put to practical use.
Japanese Patent Application 2002-303052

  Originally, coastal seaweeds (Honda Walla, Wakame, Aosa, etc.) are decomposed and excreted as foods of living organisms (Hamatobismuth, Hamadangumushi, Hamabe flies, Isozymkade, Earwig, Isoworms, etc.) on the beach, supplying organic matter to the sandy beach, It plays important roles such as water retention. Current countermeasures for beach beautification and conservation are only cost problems or temporary solutions, and are practical. The realization of the present invention makes it possible to treat seaweed in a form close to nature, and as a result, it is possible to beautify and preserve the beach, which is an indicator of the natural environment of the land and sea, and to help eliminate the significant processing costs of beach management. I want to.

  In the present invention, a large amount of sea earthworms that feed on seaweeds are cultivated in advance, and by utilizing this food property, the coastal seaweeds can be reused for resource conservation and beautification. Contributes to the purification of organic pollution on the beach. In addition to providing a place where children can learn about the natural circulation and the importance of life, and selling it as fishery feed and livestock feed including poultry farming as well as fishing bait that shines the grown earthworms Profitability. In addition, the rate of assimilation of ingested food is poor, and nearly 80% is excreted out of the body as feces, so the feces are likely to be an initial feed for seafood with high digestibility and high nutritional value. . As a result, the route to recycle the seaweed drifted seaweed will be expanded, and if it can be generated in the form of a consignment from the local government from the viewpoint of raw material recovery costs, it will lead to one fixed income, sustainable community business -It can be a system.

  The products manufactured in the present invention are mainly fishing bait, fish feed, poultry feed, and all livestock feed. Looking at the future of animal feed, internationally, it is moving toward a large amount of bioenergy as an energy raw material. Therefore, substitution of animal feed is inevitable. Its usefulness as an alternative feed will increase. As a secondary effect, it is expected that the beach will be beautified and preserved, and that its processing costs will be eliminated.

Figure 1 suggests recycling coastal seaweed that uses the food habits of earthworms to help preserve and beautify the coast, contribute to the purification of organic pollution on the beach, A community business system that combines benefits such as providing a place to learn the importance, and the profitability of using recycled earthworms as feed ingredients and the cost of collecting raw materials from local governments.

  In the present invention, about 300 islet earthworms were collected on the Miura Peninsula coast and used for the test. The breeding container was a large pot of unglazed pottery, and the bottom hole for drainage was closed with gravel. Since the earthworm is mainly buried in the place where the humidity is 80 to 100% and the sand is 10 to 20 cm, the breeding floor is filled with sand to a depth of 30 cm. Water was sprayed regularly to maintain humidity. Watering had no effect on breeding in seawater or fresh water. The breeding temperature was set to 10 to 30 ° C. Breeding temperature was an important factor in the growth of earthworms. A hand-sorting method was used to measure the earthworm population. The optimum breeding temperature for growth was 20-25 ° C., the growth at 10 ° C. was very bad, and the growth stopped at 5 ° C. It became clear that earthworms drowned rapidly at a breeding temperature of 35 ° C or higher. Furthermore, if there is no sand layer on the breeding floor, the earthworm feels stress or grows very bad.

  Since the earthworms are swarmed only in composted seaweeds and not in fresh seaweeds, the food for the earthworms is seaweed with microorganisms that have been laid for about 4 weeks. I was fed on top. In two weeks after the seed isworm was introduced, young earthworm (5 mm) was generated in composted seaweed. Two months later, the earthworm that has grown to 300g, which is about twice as much, was introduced into the 10kg coastal seaweed that was buried from the high tide line of the beach on the land side (within depth cm). 65%. However, the seaweed weight loss rate varied greatly with breeding temperature.

  Coastal seaweeds are buried on the beach, part of the organic matter is anaerobically decomposed, and black-colored organic matter polluted sand lump favors grouping, so some of the organic matter is anaerobically decomposed and black The organic matter-contaminated sand block exhibiting the above was sterilized by heat sensitization, and the section where the earthworm was put therein and the section where it was not placed were provided, and the change of the acid volatile sulfide (AVS) was observed. The group where no earthworm was not added was 0.45 mg / g at first, but reached 0.54 mg / g after 2 months. The section where the earthworm was introduced was 0.45 mg / g immediately after the introduction, but it became 0.15 mg / g two months later, and the earthworm consumed the sulfate-reducing bacteria that decomposed organically and proliferated. As a result, it became clear that generation of hydrogen sulfide was suppressed.

  After drying 600 g of dung sand discharged from the earthworm by a constant temperature drying method, 100 g of granular Detritus collected by passing through a sieve having a mesh size of 10 μm or less could be obtained. Moreover, as a possibility test as a live bait for fishing, the luminescent liquid flowed out and the white light emission could be visually observed when artificially injured the ring zone part of the earthworm in the dark. Further, this luminescent solution was sucked on a filter paper and naturally dried, and then light was emitted again when 1 ml of pure water was added in the dark. As a result, it was confirmed that the luminescent material was not inactivated or decomposed under natural drying. Therefore, 1 kg of frozen earthworms was freeze-dried by vacuum freeze-drying at a trap cooling temperature of −40 ° C. and a trap dehumidification capacity of 1 L / time, and then powdered to 150 g with a desktop coffee mill. When it was tested whether or not it would react with 1 ml of water, it emitted white light for about 10 minutes. Furthermore, when 100 g of powder was used for the analysis of basic nutritional components as animal feed, 65% was protein, amino acid and iodine amino acid composition was varied, and mineral components, vitamins B1, B2 and B6 were also abundant. The nutritional value was not inferior to fish meal.

  It is well known that some of the light-emitting substances possessed by Isomi earth are used for organic LED research and development, and it cannot be said that various chemical substances possessed by Isomi earth are well researched and developed for pharmaceuticals and health foods. It is not done, and there is a big role as a raw material source for earthworms.
