figures). Other sources of revenue are the sale of postage stamps and coins, tourism, and customs and harbour dues. Fishing Fishing takes place around South Georgia and in adjacent waters in some months of the year, with fishing licences sold by the territory for Patagonian toothfish, cod icefish and krill. Fishing licences bring in millions of pounds a year, most of which is spent on fishery protection and research. All fisheries are regulated and managed in accordance with the Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR) system. In 2001 the South Georgia government was cited by the Marine Stewardship Council for its sustainable Patagonian toothfish fishery, certifying that South Georgia met the MSC's environmental standards. The certificate places limits on the timing and quantity of Patagonian toothfish that may be caught. Tourism Tourism has become a larger source of income in recent years, with many cruise ships and sailing yachts visiting the area (the only way to visit South Georgia is by sea; there are no airstrips on the Islands). The territory gains income from landing charges and the sale of souvenirs. Cruise ships often combine a Grytviken visit with a trip to the Antarctic Peninsula. Charter yacht visits usually begin in the Falkland Islands, last between four and six weeks, and enable guests to visit remote harbours of South Georgia and the South Sandwich Islands. Sailing vessels are now required to anchor out and can no longer tie up to the old whaling piers on shore. One exception to this is the recently upgraded/repaired yacht berth at Grytviken. All other jetties at former whaling stations lie inside a exclusion zone; and berthing, or putting ropes ashore, at these is forbidden. Yachts visiting South Georgia are normally expected to report to the Government Officers at King Edward Point before moving round the island. Postage stamps A large source of income from abroad also comes from the issue of South Georgia and the South Sandwich Islands postage stamps which are produced in the UK. A reasonable issue policy (few sets of stamps are issued each year) along with attractive subject matter (especially whales) makes them popular with topical stamp collectors. There are only four genuine first day cover sets from 16 March 1982 in existence. They were stamped at the South Georgia Post Office; all those in circulation were stamped elsewhere and sent out, but the only genuine
