Abstract

The present invention relates to a concrete artificial reef for seaweed submerged in the seabed of coastal seas and used to create a marine forest. More specifically, the artificial reef for seaweed to reduce pirate organisms is configured such that engraftment rods protruding at a predetermined height are disposed, at regular intervals, on an outer surface of a reef main body with a trapezoidal cross section, a blocking frame and a blocking tube, made of a copper material, are connected respectively to an edge of a lower end side of the reef main body and an outer surface of an upper end of each engraftment rod, and an engraftment groove is formed in an upper surface of each engraftment rod to induce rooting of seaweed or connect a breed yarn string to which germinated spores of seaweed are transplanted. Accordingly, the blocking frame on the lower end side of the reef main body can primarily suppress pirate organisms which prey on the seaweed such as sea urchin and abalone from climbing up from the sea bed to a surface of the reef main body. The blocking tube on the upper side of each engraftment rod can prevent the pirate organisms such as sea urchin and abalone attached to and grown on the surface of the seaweed main body from climbing up to the upper surface of each engraftment rod. Through this, it is possible to prevent the pirate organisms from damaging various types of seaweed rooted on the upper surface of each engraftment rod, and thus, the seaweed can safely and densely grow at an outer side of the reef main body. Therefore, it is possible to effectively create a marine forest, which is a basic element of a marine ecosystem, so that it is possible to substantially contribute to a marine ranching project as well as a profit-making business of a fishing village, such as a fishing site.

Description

Artificial reef for a seaweed with a decrease function of natural predators}

The present invention relates to an artificial seaweed for seaweed made of concrete material that is settled on the sea floor in the coastal sea area, and used for the formation of a marine forest, and has a constant spacing of the rods protruding at a predetermined height over the outer surface of the fish body having a trapezoidal cross section. The seaweeds rooted in the upper end surface of each of the rods as distributed and arranged, and connecting the blocking frame and the blocking tube made of copper material to the lower edge and the outer surface of the upper end of each rod of the eocho main body The present invention relates to a seaweed artificial reef for reducing pirate creatures, which is capable of growing safely and densely on the outer side of the reef body without being damaged by sea urchins or sea urchins.

In recent years, coastal waters in Korea have been gradually disappearing due to various environmental factors such as excessive inflow of various nutrients and abnormal high temperature phenomena. Instead, coastal waters are gradually devastated by the rapid breeding of uncalcified lime algae, the main culprit of whitening.

The bleaching of coastal waters began in 1996, and in 2004, about 34% (4,540 ha) of Jeju coast and 14% (2,413 ha) of East Coast coast. The occurrence of such whitening in coastal waters is expected to continue to increase.

When various seaweeds disappear due to the whitening phenomenon, shellfish and invertebrates such as abalone, seashell or sea urchin, which serve as a prey and hide, are also disappeared, as well as spawning grounds and habitats of fish based on seaweeds. Destruction leads to a serious problem of the rapid reduction of useful fish stocks that can be caught in coastal waters.

As a result, artificial reefs have been installed in the coastal waters of the coast, especially in shallow waters of about 20m, to create sea forests by seaweeds, and to grow various shellfish and fry. Efforts have been actively made to provide the feeding grounds, hideouts, and spawning grounds for fish, and in response to this trend, various types of artificial reefs for seaweed have been developed and installed.

However, most of the seaweed artificial reefs developed so far are made of concrete structures having a specific shape so as to provide an easy surface for growth and growth of seaweeds. Only a uniform method is used to spread out the protruding frame, incision grooves or holes to provide shells and fry of hides on the surface, and sea urchins and abalones that grow on the surface of artificial reefs The protection from pirates was not provided at all.

As a result, when seaweed artificial reefs, which are concrete structures, are settled to the sea floor in the coastal waters, various seaweeds may primarily grow and grow on the surface of the artificial reefs. After a certain amount of time, the sea urchins and abalones can easily climb to the spot where the seaweeds are located and eat the algae. Difficult situations arise.

In order to compensate for the above problems, the artificial lines of artificial reefs can be attached to the surface of artificial reefs by artificially transplanting germinated spores of seaweeds in land tanks, or to secure a more sufficient natural active surface of seaweeds. It is known that the size and structure are very large and complicated, but even in this case, an uneconomic problem that excessively raises only the cost of manufacturing and planting artificial reefs can be caused while the reduction rate of seaweeds by pirates such as sea urchins and abalones is hardly reduced. It became.
