3면이 바다로 둘러싸인 우리나라는 육지의 농업과 함께 바다에서의 어업이 중요한 생산자원으로 이용되고 있다.With three sides surrounded by the sea, Korea's farming and land fishing are used as important production resources.

그러나, 바다는 함께 공유하고 있는 국가간에 서로 많은 어획량을 늘리기 위해 상대방측 어로구역을 침범하는등의 행위에 따른 국가간의 마찰로 잡는 어업에서 기르는 어업으로 변화되고 있으며, 그 방법중의 하나로 연안에 인공어초를 설치하여 어류 및 패조류를 보호 육성 할 수 있는 것이다.However, the sea is changing from fishing caught by friction between countries due to the invasion of other fishing zones in order to increase the catches among the countries shared with each other, and one of the methods is artificial fish on the coast. By installing candles, fish and shellfish can be protected and nurtured.

이와 같이 연근해의 어류 및 패조류를 보호 육성하기 위하여 설치하는 인공어초는 그 재질을 시멘트로 하여 하나의 구조물이나 여러가지 모양의 단위어초를 결합한 인공어초로 구성하여 해류가 있는 평탄한 해안선 지대에 설치하여 어류와 패조류의 먹이생물인 플랑크톤과 해조류를 증식케하여 어류와 패조류에게 먹이와 휴식공간을 제공하는 것이다.The artificial reefs installed to protect and nurture the fishes and algae in the near-shore seas are composed of artificial reefs combined with a single structure or united reefs of various shapes using cement as its material and installed on a flat coastline with currents. It is to provide food and rest space to fish and shellfish by multiplying plankton and algae, which are food organisms of shellfish.

그러나, 상기와 같은 종래의 인공어초는 그 재질이 시멘트로 되어 있어 물과 혼합하여 인공어초를 제작시 시멘트의 특성상 수화반응을 하게 되어 PH13인 강알칼리로 독성이 매우 강한 수산화칼슘이 발생되어 작업자의 손바닥등의 인체에 좋지 않은 영향을 미치는 것은 물론 인공어초 설치목적인 연근해 어족 증식 및 해양환경보호에 어긋나는 독성을 발생시키고, 특히 조류의 이동이 적은 장소에서는 독성에 의한 심각한 피해가 발생되어 오히려 어족자원을 고갈시키는 문제점이 있는데, 이는 인공어초 설치후 최소 만 2년까지는 독성의 피해가 계속 되는 것으로 알려져 있다.However, the conventional artificial reefs as described above are made of cement and mixed with water, and when the artificial reefs are manufactured, they undergo a hydration reaction due to the characteristics of the cement. It not only adversely affects the human body, but also generates poisonous fish that is incompatible with the propagation of marine fishes and protection of the marine environment for the purpose of installing artificial reefs. There is a problem, which is known to continue toxic damage for at least two years after the installation of artificial reefs.

본 발명은 상기와 같은 문제를 해결코자 하는 것으로, 인공어초의 구성물인 단위어초를 황토를 주성분으로 하여 고열에서 소성가공함으로써, 인공어초에서 독성이 발생하는 것을 방지하고, 원적외선이 방사되게 함으로써 작업자의 인체를 보호함은 물론 연근해 어족증식 및 해양 환경보호에 뛰어난 효과가 있으며, 특히 조류의 이동이 적은 지역에서 적조 및 녹조의 발생을 억재시키는 효과가 뛰어난 황토를 주재로한 환경친화적인 인공어초 및 그 제조방법을 제공하는데 그 목적이 있다.The present invention is to solve the above problems, by the plastic processing at high temperatures with the main component of the reef as the main component of the artificial reef to prevent the generation of toxicity in the artificial reef, the far infrared rays are radiated to the human body of the worker In addition, it protects the fishes and has excellent effects on the offshore fish breeding and marine environment protection.In particular, environmentally friendly artificial reefs and its manufacture mainly based on yellow soil, which are excellent in inhibiting the occurrence of red and green algae in areas where the flow of algae is low. The purpose is to provide a method.
