Biography Atle Mortensen

At Nofima I work as senior scientist and the head of The National Cod Breeding Program. I have a doctoral degree in zoo-physiology from University of Tromsø, 1985. My research in aquaculture has, to a large extent, been focused on how the physical, chemical and social conditions affect growth, health and welfare of different aquaculture species. The aim has always been to optimize the culture conditions, based on knowledge about the environmental requirements of the different species. I have worked with several aquaculture species mainly; Atlantic salmon, Arctic charr, Atlantic cod, sea urchin and red king crab. Apart from applied research, I have been involved in commercial aquaculture for several years. I have also broad experience in teaching aquaculture at college and university level; the later years as professor II in aquaculture technology at University of Tromsø.
