PROBLEM TO BE SOLVED: To solve a problem that since reef building corals, marine algae, etc., having aesthetic appreciation values have higher values in sale in a state in which they adhere to rocks, reef building corals, marine algae, etc., are advantageously sold at higher prices when grown in terms of fishing in a state in which they adhere to rocks, however, at present, in a growing method using a natural sea area, with which one pile is used for one growing organism, only a small amount of reef building corals is barely cultured in poor economic efficiency. SOLUTION: A dendritic three-dimensional structure having side branches from a pole is used, the side branches are provided with retention positions for fixing rocks and rocks are fixed to the retention positions with wires, rubber and strings. Naturally reef building corals and marine algae are previously adhered to the rocks to be fixed. COPYRIGHT: (C)2008,JPO&INPIT
