The present invention relates to a conical fish reef comprising: a conical fish shelter having a conical frame as a base provided with three concrete pillar frames and three concrete bottom frames and three concrete wall parts integrally formed in the inner central part of the shelter while a bottom surface of the shelter is opened window holes formed as a flowing passage on the wall parts of the conical fish shelter and an octopus shelter installed under the conical fish shelter and provided with a radial connecting bridge and a moving passage and a hiding space on a central body. Thus, a narrow edge space basically provided by the conical frame and a narrow edge surface necessary for various shellfish and algae adhesion over a portion in which each corner portion of the conical fish shelter connected to the pillar frame are sufficiently secured a shadow space suitable for hiding and eating activities of various fishes in a lower portion of the conical fish shelter is also sufficiently secured and octopuses which are high value fish are gathered in the octopus shelter in the bottom side to thereby hide and grow. Accordingly, a merit of conical fish reef in which stable and durable installation of the fish reef is enabled and a merit of a shelter house-type fish reef which is suitable for massive gathering and safe protection of various aquatic organisms including fishes are integrated, and thus, a very excellent fish reef function can be obtained. Furthermore, the structure of the fish reef itself is relatively simply configured and thus the manufacturing cost thereof can be remarkably reduced.COPYRIGHT KIPO 2016본 발명은 3개의 콘크리트 기둥프레임과 3개의 콘크리트 바닥프레임이 제공하는 삼각뿔 프레임을 베이스로 하여, 그 내측 중앙부에 바닥면이 개구된 상태로 3개의 콘크리트 벽체부가 일체로 형성된 삿갓형 어류쉘터를 배치시키고, 이 삿갓형 어류쉘터의 벽체부상에 유동통로로서의 윈도우홀을 형성시키는 한편, 삿갓형 어류쉘터의 하부측에는 방사상의 연결다리와 센터바디상에 이동통로와 은신공간이 제공된 문어쉘터를 설치함으로서, 삼각뿔 프레임이 기본적으로 제공하는 좁은 모서리 공간과 함께 삿갓형 어류쉘터의 각 꼭지점 부분이 기둥프레임과 연결되는 부위에 걸쳐 각종 패조류의 활착에 필요한 좁은 모서리 공간을 충분히 확보토록 함은 물론, 삿갓형 어류쉘터의 하부에
