was granted 9 green licences at the end of 2014. In retrospect, later 9 other licences
owned by NRS was converted to green licences, giving NRS a total of 18 green licences.
NRS's green licences have several conditions and contribute to develop the
aquaculture industry towards a more sustainable production. One of the
conditions was to produce sterile fish with triploid salmon. In collaboration with the Institute of Marine
Research and other professional institutions, NRS has for many years made a
significant effort to develop and improve the production of triploid salmon. One
of the experiences with triploid salmon is that it seems to be more exposed to
bacterial and viral diseases.
