Field of work

I have been researching and teaching in the field of water quality in closed-containment fish farms for about 30 years, and I have specialized in the long-term effects of CO2 on salmonids. We have had almost continuous support for our research from the Research Council of Norway and from the aquaculture industry's research fund. For many years, there has been a focus on CO2 both in aquaculture and in terms of ocean acidification.

We are now participating in the project 'Nephrocalcinosis and hemorrhagic smolt syndrome - causal relationships and opportunities for prevention'. This is about the fact that farmed smolts develop calcareous precipitations in the kidneys, partly due to elevated levels of carbon dioxide in the water. I also participate in research on recirculation systems (RAS) in aquaculture.

I participate in the editorial board of international journals.

Courses taught

I am teaching in practical work and in water quality.

Research areas

I am doing research on water quality in aquaculture facilities and ocean acidification. The research focuses on CO2, ammonia and metals as limiting factors for water exchange, fish physiology and nephrocalcinosis. It is also focused on alkalinity, pH and the carbonate system in the sea.

Research groups

I am research leader for the research group Chemistry, energy and aquaculture
