The amount of saury caught is declining due to rising seawater temperatures and intensified competition from Chinese and Taiwanese fishing vessels. The breakdown is 9,7044 tonnes inside Japan and Russia's EEZ=exclusive economic zone, and 2,1087 tonnes on the high seas, the lowest since 1997, when Japan capped the catch.
Japan the government plans to urge China, Taiwan, and other countries to further strengthen resource management, such as lowering the upper limit on fish catches in the entire North Pacific.
