Aquaculture is one of the fastest growing productions and the value of aquaculture is now about to pass the value of capture fisheries. Among the Nordic countries, Norway in particular has been able to create a large aquaculture industry with high growth rates over a number of years. The other Nordic countries have only had limited growth, but have a high unutilised potential. There is a need to identify opportunities and limitations for increased growth with due care for sustainability and environment. This report identifies seven focus areas with special potential for creation of a sustainable, competitive Nordic aquaculture sector. These areas are new feeds, better use and reuse of nutrients (nitrogen, phosphorus and carbon), value adding of by-products, technological and regional development, domestication of new species and reduction of energy consumption. The aquaculture sector with its strengths and weaknesses is described for each of the Nordic countries.The report is compiled on basis of contributions from a Nordic group of experts. It was presented at a seminar on Green Growth at the annual meeting of the Nordic Ministers of Fisheries in Trondheim, July 2012.
