PROBLEM TO BE SOLVED: To provide a method for producing an artificial fish-breeding reef by producing a mold composed of a water-soluble material and using the mold. SOLUTION: Resin nets 33 are attached to the inside walls, longitudinal bars 41 and crossbars 42 of a box part 32. Each side of the box part is equipped with through holes for inserting the longitudinal bars 41 and the crossbars 42. The top of the box part is open. A great number of small holes 43 are bored through the sides of the box part 32 to pull out water. The gel-like water-soluble material sufficiently kneaded with water is poured into the box part 32 and water is pulled out from the small holes 43. When drying is advanced in a certain degree by air drying, etc., the longitudinal bars 41 and the crossbars 42 are removed. Then, after the material in the box body 32 is sufficiently dried by blowing hot air into the hollow part, the box body 32 is broke down to take out the solidified mold. COPYRIGHT: (C)2005,JPO&NCIPI
