Historically, fishing has been one of the basic economic activities along the Norwegian coast (Seppänen, 1995). The Norwegian fishing industry, including aquaculture, is one of the largest export industries in the country, accounting for 5-10 per cent of total exports when fish farming is included (Selnes, 1995; Aasjord, 2002). Both the ground-fish and pelagic fisheries are traditionally important. The principal species economically for sea fishing is cod, but haddock, capelin and herring are also important (Hoel, 1994).
