Antarctic fisheries in 2000-01 (1 July-30 June) reported landing 112,934 metric tons. Unregulated fishing, particularly of Patagonian toothfish, is a serious problem. The Convention on the Conservation of Antarctic Marine Living Resources determines the recommended catch limits for marine species. A total of 13,571 tourists visited in the 2002-03 antarctic summer, up from the 11,588 visitors the previous year. 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. Antarctica: Population / Demographics Population (July 2005) no indigenous inhabitants, but there are both permanent and summer-only staffed research stations Population density (people/sq km) (2005) - [an error occurred while processing this directive] Antarctica: Infrastructure Telephones - main lines in use 0 Telephones - mobile cellular NA Roadways (km) [an error occurred while processing this directive] Antarctica : References & Data Sources  Environment, Land use / Resources, Economy, Population / Demographics, Infrastructure, Health -- CIA World Factbook, 2005  Forest Cover, Forest types, Breakdown of forest types, Change in Forest Cover, Primary forests, Forest designation, Disturbances affecting forest land, Value of forests, Production, trade and consumption of forest products -- The FOOD AND AGRICULTURE ORGANIZATION OF THE UNITED NATIONS's Global Forest Resources Assessment (2005) and the State of the World�s Forests (2005, 2003, 2001)  Protected Areas, Plant and animal biodiversity -- United Nations Environment Programme - World Conservation Monitoring Centre (UNEP-WCMC). 2004.
