One underwater tent type artificial reef.

As is well known, coastal fisheries are shrinking due to the expansion of landfills for the development of coastal cities and the construction of industrial complexes, and the deterioration of fisheries is accelerating due to the inflow of marine oil spills and pollutants such as living and industrial wastewater.

In addition, fishery resources are decreasing every day due to overfishing that exceeds the reproductive capacity of fisheries resources. Therefore, it is noted that the increase of coastal water, farming, and productivity improvement are emphasized to secure high-quality protein sources and provide stable national food supply.

Therefore, the farming of coastal fisheries should be done by cultivating and releasing superior fish seedlings, and artificial fishes need to be protected and grown to produce artificial fish.

In other words, appropriate artificial reefs have been developed for the development of the environment required for the life history physiology and ecological characteristics of various fish and shellfishes, and the habitat environment of coastal fishes has been improved to secure fishery resources.

For this reason, artificial reefs have been known for the purpose of improving the environment of aquatic organisms, and various artificial reefs have been conceived and developed, but these reefs are mostly concrete structures, of which 80% are not effective as the concrete reefs shown in FIG. Improved reefs can also be seen, but they are also concrete structures or waste ships that cannot contaminate seawater and form effective and natural reefs.

Requirements for artificial reefs should be: First, the fish should have a complex structure and sufficient internal space to easily escape from predators; Third, there should be no weakening of the material and no toxic spill over time. Fourth, the stability, functionality and constructability of the installation area will be excellent.

However, the disadvantage of conventional concrete reefs is that it is difficult to manufacture complex shapes of reefs with sufficient space inside because they are made of concrete, and once installed, they are impossible to move. It is a source of environmental pollution at the bottom of the sea.

In addition, when the reefs are installed, the flow distribution around the reefs is changed, and due to the changed flow distribution, the bottom surface around the reefs is crushed, causing the reefs to be buried by the soil.

In order to correct the closed end of the above known concrete block-type artificial reef, another applicant of the present applicant has constructed a space in which the weight and young meat can move on the support while controlling the water flow by standing a flexible plate in the water. .

The present invention for improving the conventional pedan and to obtain another reef that complements the improved reef of the prior application is configured to be installed in the shape of a tent in the water with a flexible film of light material such as fiber membrane, easy to configure It can be freely adjusted in size and formed as a folding or assembly, which is easy to transport and install, easy to collect and recover, and the flow of seawater, which is a natural phenomenon even after installation, is controlled to increase the downstream area. In addition, the size and height of the water flow can be increased to improve the fishing environment, and if properly arranged, the wave energy is attenuated to improve not only the aquatic environment but also the fishing environment of the aquatic environment. It is intended to be extensible.
