Senior Scientist
I have for 25 years with how environmental and biological factors interact to determine the fillet color of salmon. This is still a relevant topic for the industry. I also work with issues related to resource utilisation and sustainability in Norwegian salmon farming. My specialised focus is on how to utilise the feed resources used in the production of Norwegian salmon, the raw materials used and the impact of Norwegian salmon farming activities in terms of greenhouse gas emissions, energy consumption and phosphorus use. I also work with issues related to farming in closed and semi-closed containment systems, with a particular focus on the optimization of farmin conditions during the production of large smolts and post smolts in closed or semi-closed containment systems.
I am a qualified biologist from the Norwegian University of Science and Technology i Trondheim, with a specialization in general zoology and physiology. I completed my PhD at UMB/Akvaforsk where I studied the pigmentation of salmonids focusing on factors that limit the utilization of the carotenoids added to fish feed. Environmental factors affecting digestibility and metabolism of the carotenoids and their impact on muscle retention are important factors that have an impact on the utilisation of the astaxanthin added to the feed.
