Are all saury in China imported from Japan?

Saury likes fish with low water temperature. In China's Yellow Sea, such as Shandong, there are saury. But now the saury you buy in the domestic market is basically caught in the high seas east of Japan and the Taiwan Province Strait. After all, the fishing season in that place is the earliest and more fertile.

It is said that saury is produced in the South China Sea, but it certainly has no commercial fishing value.

Also, the Japanese fish with small fishing boats, and they pay more attention to quality. If it is frozen and shipped to China for sale, the price will definitely be high. Therefore, it will not be imported from Japan.
