With a coastline of more than 83 000 km, including fjords and islands, Norway is one of the world’s leading nations regarding the production from marine fisheries and aquaculture. The fisheries sector has always played a key social and economic role, nationally and regionally, and has been the basis for settlement and employment along the entire Norwegian coast. Intensive farming of Atlantic salmon is by far the most important activity, accounting for more than 80 percent of the total Norwegian aquaculture production. Rainbow trout is also important.
