In recent years, the natural herb is gradually decreasing. The reason is that the phenomena due to the environmental changes due to the rise of sea water temperature and the deterioration of photosynthesis of seaweed are gradually increasing, and many reefs are disappearing due to their lack of function. Yields are significantly reduced due to the loss of food and hides of living things (fish, shellfish, seaweed, etc.).

Accordingly, in recent years, artificial reef groups have been formed on the coastal seabed to provide natural habitats and protected growth of aquatic plants such as algae within a short period of time, providing food and habitats for fish and forming aquatic ecosystems, thereby increasing the production of fish. Doing.

In addition, when catching a net from the bottom when catching a fishing net, such as fishing net low fishing nets to prevent excessive overfishing of low fishing nets to protect the fry and also serves to stabilize the ecosystem.

Artificial reefs that have been artificially formed on the sea floor to prevent overfishing of low-impact fishing boats and can be attached and propagated by seaweeds are artificial structures that are provided in the sea water for the growth, propagation and collection of seaweeds and shellfish. Or an artificial structure formed of steel or the like.

Such artificial reefs create an environment in which algae can attach to and propagate, where fish can live or lay nests, and abalone, seashells, and other fisheries that feed on micro-animals that feed on algae It is configured to grow a lot of animals.

The general shape of the artificial reef as described above has a rectangular cylinder or rectangular parallelepiped structure, and a through hole penetrating the outside and the inside is formed so that the current flows through the through hole of the square cylinder, so that the inner space inside the square cylinder It is a good place to provide an environment where fish can inhabit and provide them with hiding places and food.

However, the conventional artificial reefs made as described above are stacked in multiple stages to form an artificial reef group, which damages the structure of the artificial reef group because the artificial reefs located at the bottom end are damaged or buried under the sea floor due to the load of the artificial reefs. There was a problem.

In addition, the artificial reefs are easily collapsed or lost due to typhoons or currents, and thus the living space of the aquatic organisms is significantly reduced, thereby hampering the habitat and growth environment of the aquatic organisms.

Accordingly, in recent years, artificial reefs having a structure to solve the problems of the conventional artificial reefs have been proposed.

As such, artificial reefs are mainly made of metal (casting, steel wire assembly), wood (including waste wood), synthetic resin series (including waste vinyl, recycled waste tires), and concrete.

Among the artificial reefs, concrete artificial reefs manufactured using concrete include Korean Utility Model Registration No. 20-0293841, wherein the artificial reefs are structured in a hexahedron shape by concrete, and the entire six sides of the hexahedron are internal. It consists of a cube-shaped skeleton so that the outside and the outside communicate with each other.
