PROBLEM TO BE SOLVED: To provide an effective and inexpensive method for rearing Zostera, comprising using a highly safe solid which is obtained by solidifying dredged soil with rapid treatment without contaminating the environment as a stable Zostera rearing base which is free from swelling and collapsing in the sea or melting again.;SOLUTION: This method for rearing Zostera comprises a process of obtaining a preliminary solid by adding a coagulating fixation agent to dredged soil, a process of obtaining a solid having 100-200 mass% of water content by solid-liquid separating the preliminary solid thus obtained, and a process of planting Zostera on the solid thus obtained followed by rearing in the sea.;COPYRIGHT: (C)2007,JPO&INPIT
