Abstract
On March, 2011, the great East Japan earthquake caused a decrease in the production of Japanese sea squirt. Since the release of radioactive pollutants in 2013, It was impossible for Japan to export seafood to Korea. Due to these circumstances, there have been various changes in the structure of the domestic sea squirt aquaculture. For example, the price of sea squirt rose for the second half of the year and increased the production of sea squirt in the eastern coast of Korea. Therefore, this paper analyzed the changes in the structure of domestic sea squirt aquaculture since the great East Japan earthquake. In addition, the paper predicted future the demand and supply of domestic sea squirt based on the outcome of the WTO dispute and suggested several directions for countermeasures.
