Economy - overview:
Fisheries in 2013-14 landed 302,960 metric tons, of which 96% (291,370 tons-the highest reported catch since 1991) was krill and 4% (11,590 tons) Patagonian toothfish (also known as Chilean sea bass), compared to 15,330 tons in 2012-13 (estimated fishing from the area covered by the Convention of the Conservation of Antarctic Marine Living Resources, which extends slightly beyond the Southern Ocean area). International agreements were adopted in late 1999 to reduce illegal, unreported, and unregulated fishing, which in the 2000-01 season landed, by one estimate, 8,376 metric tons of Patagonian and Antarctic toothfish. In the 2014-15 Antarctic summer, 36,702 tourists visited the Southern Ocean, slightly lower than the 37,405 visitors in 2013-14 (estimates provided to the Antarctic Treaty by the International Association of Antarctica Tour Operators, and does not include passengers on overflights and those flying directly in and out of Antarctica).

Marine fisheries:
the Southern Ocean fishery is relatively small with a total catch of 278,701 mt in 2016; the Food and Agriculture Organization has delineated three regions in the Southern Ocean (Regions 48, 58, 88) that generally encompass the waters south of 40° to 60° South latitude; the most important producers in these regions include Norway (160,947 mt), China (65,020 mt), and South Korea (23,072 mt); Antarctic Krill made up 98% of the total catch in 2016, while other important species include Patagonian and Antarctic toothfish
