Fisheries Senior High School, Fisheries Cooperative and Prefectural Fisheries Technology and Development Center collaborated to restore Sargassum beds in an deforested area off Ibusuki City, Kagoshima Prefecture. For training of SCUBA diving, 15-18 students and instructors of the high school dived into the area and removed diadematid sea urchins (mostly Diadema D. savignyi) from there. From 2005 to 2009, they removed more than 60 thousand urchins on 10 days in total. In addition, Fishermen in the cooperative set the mature Sargassum by sticking them into mid-layer gill nets on the bottom. Fisheries Technology and Development Center could recognize the restoration of some Sargassum beds.
