The present invention relates to a trapezoidal mold seaweed forest structure, in particular to effectively recover the coastal fisheries devastated by baekhwa phenomenon artificially create seaweed forest, and to the habitat and spawning grounds such as adherent animals and fish to feed the seaweed forest A trapezoidal mold deforestation structure that can be utilized.

In recent years, the seashore has been transformed due to the strong current of Kuroshio turbulence, the Elino phenomenon, and the pollution of the train, and the seaweed, kelp, and rhubarb, which have been inhabiting the existing coast, disappeared. Algae (also called 'lime algae') are breeding in large quantities, causing a lot of bleaching to cover rocks.

The phenomena of the bleaching have not yet been identified. However, it is attributed to the increase in water temperature and the inhibition of photosynthesis of algae due to the spread of Kuroshio turbulent forces and environmental changes.

Algae are generally classified into green algae, red algae and brown algae. The algae that cause bleaching are algae belonging to the red algae. They are red or pink at the beginning of development but become white after they die over time. This is because the limeless algae have calcium carbonate (CaCO3) as the main component and only remain after limestone.

In this way, when the endangered algae die at the end of their life, they do not disappear like other plants, and calcium carbonate, which is a component of the endemic algae, remains to cover the rock surface as cement.

In addition, the rust free coral algae has a characteristic of spreading to a wide area in a short time with a strong characteristic of breeding while spreading to the side and is spreading more widely.

The algae algae usually develops in May to June, before the spores of useful algae are released and germinate, and then rapidly reproduce and die. In the seas where whitening occurs, The spores are not only covered and extinguished by the coral reefs, but the surviving spores are eaten by the sea urchins, seashells, chestnuts, and the like before they grow into leaflets, and thus no algae can exist. The sea is devastated in a desert like appearance.

These bleaching phenomena are rapidly spreading over the east coast, causing coastal fisheries to be devastated, and marine habitats such as seaweed and kelp are rapidly destroyed, resulting in changes in food chain structure such as abalone and sea urchins, and marine ecosystems including the spawning and habitat environment of various fish. It has a significant impact on the situation.

As reported by various media outlets, the phenomena occur throughout the east coast, are spreading to depths of about 10m off the coast, and have occurred in large areas of total fishing grounds to cause great damage to fishermen. .

As such, once the phenomena of whitening occurred, the depletion of marine resources as well as eutrophication is promoted, and it is known that natural healing is not possible without artificially restoring it.

There are several ways to restore the fishing grounds where the phenomena occurred, such as low underwater longage facilities, hanging algae imitations, and transplanting seaweed seedlings.

Among these, seaweed seedlings are a method of installing artificial structures in the sea and artificially attaching seaweed seedlings.

As such, there are several ways to install artificial structures in the sea and to artificially attach seaweeds as follows.

First, attaching seeds from mother seaweed to artificial structures to grow; second, collecting roots of some grown algae and attaching them to artificial structures or natural rock with epoxy resin bond; After attaching to a rope and growing to some extent, there is a method of binding a rope with a young seaweed to an artificial structure or natural rock to take root as the seaweed grows.

However, the first method has a problem that it is possible to test a small amount, but it is difficult to propel the business because of the large size of the artificial structure, and the second method is very difficult to succeed due to the problem of binding of the bonded bond. There was a problem.

In the third method, ropes with artificial structures (for example, concrete reefs) installed in the sea or young seaweeds attached to natural rocks are fastened to the grooves formed in the artificial structures with fasteners, etc. There was a problem that the algae transplanted into the artificial structure was devastated without being grown properly due to being eaten by the marine animals such as chestnut beetle.

Accordingly, the present invention has been made to solve the above problems, the present invention is to provide a trapezoidal mold seaweed forest structure that allows perennial seaweeds to thrive in the water where the phenomena occurred to provide a spawning ground and habitat for fish.
