The various technologies to remove the factors which disturb forming of seaweed beds were mentioned on 'Isoyake Recovery guideline' (Fisheries Agency 2007). The cases and the problems which used artificial substrata to eight elemental technologies shown in the guideline were introduced in this report. After settling these substrata as the measure to restore seaweed beds, periodic monitoring to observe the effect should be implemented. Moreover, after settlement of the artificial substratum, the "softer" measure must be implemented (i.e., removal of sea urchins and herbivorous fishes). In these processes, new products which correspond to latest problems will be developed.
