PROBLEM TO BE SOLVED: To provide a structure for growing seaweed capable of securely fixing a seaweed seedling(s) to a fixing matrix in a short time.SOLUTION: The surface of a fixing matrix to be the anchorage of seaweed is coated with a seedling-containing solution obtained by dispersing one or two or more seaweed seedlings selected from the group consisting of a migrator, a gametophyte and a young sporophyte into the first polymer water solution having viscosity. Next, the surface of the fixing matrix and the surface of the seedling-containing solution are coated with the second polymer water solution so as to cover the coated seedling-containing solution. Finally, the second polymer water solution is gelled to form a polymer gel film covering the seedling-containing solution.COPYRIGHT: (C)2014,JPO&INPIT【課題】短時間で確実に海藻種苗を着定基質に定着させることができる海藻育成用構造体を提供すること。【解決手段】海藻の足場となりうる着定基質の表面上に、粘性を有する第1高分子水溶液中に遊走子、配偶体および幼胞子体からなる群から選択される1または2以上の海藻種苗を分散させた種苗含有液を塗布する。次いで、塗布された種苗含有液を覆うように、着定基質の表面上および種苗含有液の表面上に第2高分子水溶液を塗布する。最後に、第2高分子水溶液をゲル化させて、種苗含有液を覆う高分子ゲル膜を形成する。【選択図】図1
