Marine fishing moratorium is an important system for the conservation of living marine resources in China. From 1 o'clock on May 5, the East China Sea fully entered the fishing moratorium in the summer season.

Single-anchor flakes (sail-type nets), trawls and other unlisted marine fishing operations are closed. Ningbo Customs has set up a "green channel" to further enrich consumers' tables and ensure the orderly supply of imported seafood to the people's livelihood market.
