Salmon industry in Japan has developed along with the improvement of hatcheries and raising technologies. Hatcheries catch salmon (Oncorhynchus keta) that return to their own revers, and spawn, raise and release fingerings. Salmon hatcheries are a starting point of local salmon industry. In 2011, Great Disaster of East Japan seriously damaged a number of hatcheries in Iwate prefecture. With concessive support from governments, fisheries cooperatives reconstructed those hatcheries having been damaged. This paper purposed to survey the recovery process of hatcheries located in Iwate prefecture and identify their sustainability in maintaining salmon industries. Economic surroundings of hatcheries have been getting worse; therefore, how to operate them in sustainable way becomes a controversial issue even after the completion of the recovery programs.
