In a relatively short timespan, aquaculture has developed into a considerable industry for the production of food, reaching more than 1.1 million tonnes in 2010, with Atlantic salmon as the most important species. The sector is still relatively young and has the potential for further growth and development (Asche and Bjprndal 2011). The important production Nordic areas in terms of volume are the Norwegian coast, Danish inland waters and the coast of the Faroe Islands. Aquaculture is now also developing in nutrient poor (oligotrophic) freshwater basins, in the Baltic Sea and in land based recirculation systems (RAS) in several Nordic regions.
