Abstract Excerpt:
Hokkaido and Iwate are major areas for salmon production in Japan as these regions have accounted for about 80% (Hokkaido) and 10–15% (Iwate) of total chum salmon annual catch in Japanese coastal waters (except recent years); Hokkaido has provided nearly 55% of chum juveniles for the stock enhancement program, while Iwate has provided 25%. The Great East Japan earthquake on 11 March 2011, struck off the northeastern coast of Japan causing a massive tsunami that severely damaged the Pacific coast of the Tohoku region. The coastal devastation was much more extensive in Iwate (the Sanriku region) where it is geographically characterized as a Ria—a deeply embayed coast with steadily increasing depth seaward—making the tsunami higher than in other areas. Important facilities for the salmon fishery, including hatcheries and processing plants as well as natural habitats for salmon, were destroyed or severely damaged by the tsunami.
