Most Fish Types Recover in 2–3 Years in Tsunami-Hit Bay (News)

Tokyo, Dec. 17 (Jiji Press)—Most types of fish and shellfish recovered in two to three years in a northeastern Japan bay washed by the March 2011 tsunami following a 9.0-magnutide earthquake, a five-year underwater survey has found.

Such early recovery was confirmed in most locations in Mōne Bay in Kesennuma, Miyagi Prefecture, showed the study led by Masuda Reiji, Kyoto University associate professor, and Yokoyama Katsuhide, Tokyo Metropolitan University associate professor.

But recovery was slow in the most inner area, where only a handful of fish types such as goby were found even five years after the disaster, according to an article on the survey results published in the US journal PLOS One earlier this week.

"Undersea creatures recover quickly considering the time needed for the regeneration of forests after a volcanic eruption," said Masuda, who has conducted underwater visual surveys in the bay every two months since May 2011.

Fishing operations gradually resumed from two years after the disaster, he added.
