BEIJING -- The China Coast Guard dispatched a fleet to conduct a patrol mission in the North Pacific Ocean from July 20 to Aug 15, the authority said Saturday.

The mission aims to strengthen fisheries regulation on the high seas, the authority said.

The fleet, comprising two ships, travelled 9,857 sea miles in total. It observed and recorded Chinese squid fishing vessels for 21 times. In addition, seven foreign public service ships and six aircraft were detected.

The mission was carried out in accordance with the Convention on the Conservation and Management of the High Seas Fisheries Resources in the North Pacific Ocean, which came into force in 2015 to better regulate fishery ships and ensure long-term conservation and sustainable use of fisheries resources in the area.
