The present invention relates to an artificial reef which can be usefully used in a foreshore which is near to the land or has a high tidal degree because a disposed position can be selected by adjusting buoyancy. The artificial reef can be easily produced so as to be economically provided. Especially, even when a part of the artificial reef is damaged by an external shock, overall buoyancy is not lost. Therefore, the artificial reef comprises a plurality of pipe members (2) and a connection member (3) which connects and combines the tube members (2) to prevent environmental contamination. Each of the pipe members (2) comprises: a buoyancy pipe (5) which is formed to have buoyancy because an inner space and an external space are closed when being sealed through a sealing cap (4) at both ends; and a raising pipe (7) which has a flowing space by which fish moves to the inside and the outside by including multiple through-holes (6) connecting the inside and the outside. |
