PROBLEM TO BE SOLVED: To maintain levels of a proliferative effect of a prey creature, and a swarming effect and a proliferative effect of an aquatic organism at certain constant levels or more over a long period of time, thereby contributing to the fishing industry.SOLUTION: A method for replacing a prey creature proliferative reef 11 that includes four substrate material units 13 formed by prey creature proliferative substrate materials 16 being accommodated in a cage-like body 17, and a base 15 where the four substrate material units 13 are disposed, and is immersed on a sea bottom 12 in large numbers includes: a lifting step for lifting old prey creature proliferative reefs 11 that are immersed, by a vessel 25; a replacing step for replacing old substrate material units 13 removably attached to the old prey creature proliferative reefs 11 lifted on the vessel 25 with new substrate material units 13; and an immersing step for immersing the new prey creature proliferative reefs 11 with the new substrate material units 13 on the sea bottom 12, etc.
