Abstract
In Hirono town, Iwate prefecture, the wave-cut bench area which was above sea level only at low tide was developed to nursery for abalone and sea urchin. As a result of the promotion of sea farming, the nursery has become major source of income in the town. However, the nursery was seriously damaged by the Great East Japan Earthquake and Tsunami. Sea urchin is one of the specialties of the town. Therefore, all the parties concerned made efforts to restart of sea urchin farming in nursery. By their efforts, 1) the restoration of the nursery, 2) the restart of sea urchin transplantation and fishing, 3) the restart of seedling production of juvenile sea urchin and 4) the restart of sea urchin direct-sales had been done in some months after the earthquake. Now, it passed for 3 years and 10 mounts after the earthquake. Restart of nursery in Hirono town went well. However, we still have some problems. For example, finding un-recovered areas and recovering abalone and sea urchin resources will take some years. Ageing and depopulation of local fishermen are also the problems. To assess the influence of the earthquake early, monitoring is effective. It is necessity to continue the survey for assessment of recovery from damages of the earthquake.
