Economy—overview: No economic activity is conducted at present, except for fishing off the coast and small-scale tourism, both based abroad. Antarctic fisheries in 1997-98 reported landing 92,456 metric tons. Unregulated fishing landed five to six times more than the regulated fishery, and allegedly illegal fishing in antarctic waters in 1998 resulted in the seizure (by France and Australia) of at least eight fishing ships. A total of 9,604 tourists visited in the 1997-98 summer, up from the 7,413 who visited the previous year. Nearly all of them were passengers on 13 commercial (nongovernmental) ships that made 92 trips during the summer. Around 200 tourists were on yachts or commercial aircraft. Most tourist trips lasted approximately two weeks.
