PROBLEM TO BE SOLVED: To provide a structure for coral growth that ensures that coral larvae implanted on a grid-like structure can be raised without being eaten or dead.SOLUTION: The structure 1 for coral growth includes a grid-like structure having the form of a net on a planar view, in which rectangular, open squares 3 are formed horizontally and vertically by combining muntins and cross rails within a rectangular frame 2, both the muntins and the cross rails having the same width as the frame 2. The structure 1 is installed at the bottom of the sea using poles 5 mounted at the four corners of the structure 1, in such a way that the structure is away from the bottom of the sea. The structure resists harmful organisms such as Acanthaster, Echinoidea, shellfish from attaching to it, thereby avoiding these harmful organisms from eating corals or scraping corals off from the grid-like structure, while also avoiding such problems as corals being killed as the structure is covered with sand, seaweed, colonial ascidians, bryozoans, etc.COPYRIGHT: (C)2013,JPO&INPIT【課題】格子状構造物に着床したサンゴ幼生が捕食されたり、死滅することなく、確実に育成できるようなサンゴ育成用構造物を提供する。【解決手段】矩形の枠2内に枠2と同じ板幅の縦桟と横桟を組合わせて矩形の開口した桝目3を縦横に形成した平面視で網状をなす格子状構造物よりなるサンゴ育成用構造物1を該構造物1の四隅に取付けたポール5により海底に該海底より離して設置し、オニヒトデ、ウニ類、貝類等の有害生物が取り付きにくく、これら有害生物による捕食や格子状構造物からの掻き落しが生じにくくすると共に、砂や海藻類、群体ボヤ、コケムシ等で覆われて死滅する、といった問題を生じにくくする。【選択図】図1
