Marine fisheries

Arctic Ocean

the Arctic fishery region (Region 18) is the smallest in the world with a catch of only 708 mt in 2019, although the Food and Agriculture Organization assesses that some Arctic catches are reported in adjacent regions; Russia and Canada were historically the major producers; in 2017, Canada, Denmark (Greenland), Iceland, Norway, Russia, and the US, along with the People’s Republic of China, the European Union, Japan, and the Republic of Korea, agreed to a 16-year ban on fishing in the Central Arctic Ocean to allow for time to study the ecological system of these waters
