An object of the present invention is to recycle mud to farms, improvement of Shugyo environment due to the use, application to seagrass beds, further to provide artificial reefs to promote the improvement of sludge environment. The invention relates to a block type artificial reefs that was solidified molded by kneading the main material and solid material such as a farm sludge generated in the yellowtail, Thailand, etc. farms. The solid material or the like is formed into a predetermined hardness, placing the block type artificial reefs to be installed submarine dropped to the location where the burnt of the seabed. Naturally as reuse and healthy soil pollution mud is attributed, it is possible to improve the Shugyo work with contributes to the resolution of environmental issues. .BACKGROUND【課題】養殖場へドロを再生利用し、この利用による集魚環境の改善、藻場への応用、さらにヘドロ環境の改善を促進する人工漁礁を提供する。【解決手段】ハマチ・鯛等養殖場で生じる養殖場ヘドロを主材料と固形材等を混練して固化成形したブロック型人工漁礁である。固形材等により所定の硬さに成形され、海底投下設置するブロック型人工漁礁を海底の焼けた場所へ設置する。公害泥土の再利用と健全な土として自然に帰し、環境問題の解消に寄与すると共に集魚機能の向上を図ることができる。【選択図】図1
