Antarctica: Economy#Scientific undertakings rather than commercial pursuits are the predominant human activity in Antarctica. Offshore fishing and tourism, both based abroad, account for Antarctica's limited economic activity.
Antarctic fisheries, targeting three main species - Patagonian and Antarctic toothfish (Dissostichus eleginoides and D. mawsoni), mackerel icefish (Champsocephalus gunnari), and krill (Euphausia superba) – reported landing 295,000 metric tons in 2013-14 (estimated fishing is from the area covered by the Convention on the Conservation of Antarctic Marine Living Resources (CCAMLR), which extends slightly beyond the Antarctic Treaty area). Unregulated fishing, particularly of Patagonian toothfish (also known as Chilean sea bass), is an ongoing problem. The CCAMLR determines the recommended catch limits for marine species.
A total of 36,702 tourists visited the Antarctic Treaty area in the 2014-15 Antarctic summer, slightly lower than the 37,405 visitors in 2013-14. These estimates were provided to the Antarctic Treaty by the International Association of Antarctica Tour Operators (IAATO) and do not include passengers on overflights. Nearly all of them were passengers on commercial (nongovernmental) ships and several yachts that make trips during the summer.
