On 25 June 2021, the Agreement to prevent Unregulated High Seas Fisheries in the Central Arctic Ocean enters into force. This is the first multilateral agreement of its kind to take a legally binding, precautionary approach to protect an area from commercial fishing before such fishing has begun. There are currently no commercial fisheries in the Arctic high seas, with most of the region covered by ice year-round. However, with an ever-increasing ice-free area in the summer, commercial fishing may be possible in the foreseeable future. The Agreement to Prevent Unregulated High Seas Fisheries in the Central Arctic Ocean aims to manage potential fishing in the high seas of this region. More information on this treaty is available here (EU) and here (USA); the text of the treaty may be found here. Previous De Maribus reporting is here.
