Abstract

PROBLEM TO BE SOLVED: To provide a net cage structure body enabling insects, larvae, fish, water plants and other underwater organisms to return to their old living areas and rivers through many seasons and enabling organisms to breed and plants to grow thick. SOLUTION: A net cage structure body is composed of a net cage 1A for the net cage structure body and broken stones or natural stones 1B. The net cage 1A is composed of a box-shaped net cage body 1A1 and a cylindrical net cage 1A2. The box-shaped net cage body 1A1 is formed by building up a wire gauze plate into box shape. The cylindrical net cage 1A2 is formed in cylindrical shape, and both ends are opened to the lateral faces of the box- shaped net cage body 1A1. The broken stones or natural stones 1B are filled in a part surrounded by the inside of the net cage 1A for the net cage structure body and the outer periphery of the cylindrical net cage 1A2.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a net cage structure having a novel structure and capable of accommodating insects and fish.

[0002]

2. Description of the Related Art Heretofore, this type is as follows. More than 50 years after the war,
Look back at the environment of the country. In 1945, clothing, food and shelter for life had been very difficult. However, there were times when the natural environment was blessed at that time, and in the era when a large amount of fish caught in the ocean, in nearby small rivers (streams), eight-eyed eels, crayfish, loach and river fish were also found near the riverside. I was able to. In addition, it is an era where a lot of river fish can be caught so interesting. That is why Japan has entered a period of economic growth, and the development of motorways, the construction of large dams, the construction of resorts, and other coexisting developments related to food, clothing and shelter have progressed, while river improvement and agricultural production In relation to the pollution of water quality caused by chemical pesticides, and the increasing pollution of rivers, nearshore coastal pollution occurs, and the people involved in the countermeasures are now struggling with environmental issues. . As explained above, from the 1950s to the 1980s, it was possible to see fine fish bodies even while fishing on the riverbank.
Looking at recent riversides, many riverbanks in the continuous block zone are noticeable, and the natural environment of meandering rivers is small. The number of fish that can reproduce while responding is reduced, and no fish, insects, or aquatic plants settled in the river are found. Efforts are being made to improve and rehabilitate the worst river environment, including the local stakeholders, throughout the country. At present, various trials and researches are being conducted, including landscapes, such as the creation of a natural riverside and tree planting on the riverbed, but it takes time to solve the problem.

[0003]

The above-mentioned prior art has the following problems. Stakeholders involved in pollution control of water pollution and waterside purification, which are said to cause the greatest damage to living organisms in the river water contained in the concrete part of the concrete revetment work on the riverbank that has been continuously constructed I am very struggling. The concrete of the riverbank concrete revetment works is not suitable for the river environment and the river landscape, and is inconvenient for the aquatic plants, flowers and birds' reproductive environment. Since it is a solid concrete structure, including the explanation above, there is no change in the river landscape with respect to nature even after many years, and it is completely unnecessary for biological ecosystems. By the way, at the time of river flooding with heavy rainfall, the shore part of the meandering part of the river is improved, there are many shore parts near the straight line, and when the river rises, the flow velocity changes significantly,
Under such circumstances, underwater creatures on the shore and on the riverside are washed away downstream and disappear when the river rises. The present invention has been made in view of such problems of the conventional technology, and has as its object to provide the following. That is, as described above, various conditions in which the natural environment is not maintained or underwater conditions such as disappearance of underwater creatures are solved in the mesh basket structure of the present invention as follows. . The net cage structure of the present invention allows many insects, larvae, fishes, flowers, famous birds, and rare birds to reside on and near the river banks and riversides as described earlier. In other words, cylindrical and square mesh baskets are incorporated in the center of the mesh basket main body, and when the river rises, it becomes a shelter as a fishway where the underwater organisms (eg, fish etc.) can live, and the underwater organisms (insects, Fish, etc.), so that they can overwinter and be able to breed in the four seasons while harboring eggs. In addition, natural stones, split stones, and coral stones are injected into the net cage body, and the characteristics related to water pollution of river water, including the complex role in the water purification characteristics of coral stones that have been heard in the history, have been considered. In addition, it is intended to greatly reduce water pollution.
