PROBLEM TO BE SOLVED: To provide a fish reef that is hard to be affected by ocean wave and tidal current without diving in the seabed and performing a lot of work.SOLUTION: This fish reef 1 includes a body part 2 comprising concrete, and multiple anchor parts 3 protruding downward from the lower surface of the body part 2 and thrusted in the ground of the seabed 7. The anchor part 3 can support the body part upward from the seabed while the tip is struck in the seabed, and is fixed in the vicinity of the lower edge of the body part so as to be penetrated in the ground of the seabed 7 by the own weight of the body part or the vertical force applied to the own weight and the body part. The installation of this fish reef is performed such that the body part is lifted with the anchor part and sunk to the seabed, the body part is supported upward from the seabed while the tip of the anchor part is struck in the seabed, and the anchor part is penetrated in the ground of the seabed 7 by applying the vertical force or vibration to the body part.SELECTED DRAWING: Figure 1【課題】海底に潜水して多くの作業を行うことなく、波浪や潮流の影響を受けにくい漁礁を提供する。【解決手段】この漁礁１は、コンクリートからなる本体部２と、該本体部２の下面より下方に突き出し、海底７の地盤内に突き入れられる複数のアンカー部３と、を備える。アンカー部３は、先端部が海底に突き当てられた状態で前記本体部を海底より上方に支持することができるとともに、該本体部の自重又は自重と該本体部に作用する鉛直方向の力とによって海底７の地盤内に貫入が可能に、本体部の下端付近に固定されている。この漁礁の設置は、本体部をアンカー部とともに吊り上げ、海底まで沈下させて、アンカー部の先端部が海底に突き当てられた状態で本体部を海底より上方に支持し、本体部に鉛直方向の力若しくは振動を作用させてアンカー部を海底７の地盤内に貫入する。【選択図】図１
