Fishing off the coast and tourism, both based abroad, account for Antarctica's limited economic activity. Antarctic fisheries in 2005-06 (1 July-30 June) reported landing 128,081 metric tons (estimated fishing 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 (Dissostichus eleginoides), is a serious problem. The CCAMLR determines the recommended catch limits for marine species. A total of 36,460 tourists visited the Antarctic Treaty area in the 2006-07 Antarctic summer, up from the 30,877 visitors the previous year (estimates provided to the Antarctic Treaty by the International Association of Antarctica Tour Operators (IAATO); this does not include passengers on overflights). Nearly all of them were passengers on commercial (nongovernmental) ships and several yachts that make trips during the summer. Most tourist trips last approximately two weeks.
