The ocean off the Tohoku region has long been a rich fishing ground, but the fisheries suffered serious damage in the 3.11 disaster. Four years on, they were showing signs of recovery, but then it was discovered that some marine products were unexpectedly suffering a new disaster. In the Shizugawa Bay in Miyagi Prefecture, many sea urchins adversely affected by the tsunami have been developing spongy roe, making them unsalable. And in Otsuchi, Iwate Prefecture, the number of scallop culturists has drastically fallen, seriously threatening the future of scallop aquaculture. To deal with these problems, help arrived from marine scientists. In cooperation with fishermen, they are using their expertise to help local fishing businesses to recover.
