Large investments for habitat enhancement to expand sea urchin habitats and to promote algal growth, transplantation to enhance the gonad production and reseeding to rebuild sea urchin stocks seem to have prevented decline of the fishery production in Japan. However, the effectiveness of these means for enhancement is still not apparent at prefectural and national levels. Ecological and genetic evaluation of wild sea urchin populations would lead to appropriate enhancement means at the exploited areas.
