Provided is an artificial reef for shellfishes. The artificial reef comprises: polygonal shaped upper and lower frames which are installed to be spaced apart from each other by a predetermined interval and have predetermined areas and heights one or more algae communication frames which are formed in a separation space between the upper and lower frames to vertically connect the same, and to induce communication between algae and algae communication holes formed in spaces between the algae communication frames. The artificial reef: can disperse waves in a short period of time when the waves caused by the algae approach to the reef, thereby increasing the stability of the reef and making communication between the algae smooth and can be stably installed in various marine environments including shore regions having high flow velocity of algae, shore regions having great difference between the ebb and the flow of the tides, etc., thereby maintaining stable habitation environments.COPYRIGHT KIPO 2016본 발명은 다각형의 일정면적과 높이를 갖고 일정거리로 이격 설치되는 상부프레임 및 하부프레임과, 상·하부프레임의 이격공간에는 조류소통프레임과 조류소통구가 형성된 패류용 인공어초를 제공함으로써 조류로 인한 파가 어초에 접근할 시에 파를 단기간에 소산시킬 수 있어 어초의 안정성을 높여주고, 조류소통이 원활하며 조류의 유속이 강한 해역과 조수간만의 차가 큰 해역 등 다양한 해양환경에서도 안정감있게 설치되어 안정적인 서식장 환경을 유지할 수 있는 효과가 있다.
