Grete Bæverfjord

I work as a Senior Scientist at the Department of Nutrition and Feed Technology in Sunndalsøra.

My main focus is on all production-related issues in farmed fish, except for those related to contagious diseases.

I have mainly worked with projects that focused on deformities and abnormalities and how they can be prevented through optimization of the feed and the fishes’ environment.

We have established an X-ray laboratory at Sunndalsøra where we capture images of fish from 1 g up to broodstock size, and often work in teams where we combine X-rays with other examination methods. We also conduct X-ray diagnostics on fish from external sources when there is capacity.

In addition, I am responsible for animal-related laboratory research at Nofima’s Research Station for Sustainable Aquaculture (PMSK) at Sunndalsøra.
