Fish Endocrinology Laboratory (FEL-group)
Short description
The Fish Endocrinology Laboratory (FEL Group) focuses on physiological and endocrine aspects of growth, health and welfare of fish, from appetite and intestinal function to disease resistance in relation to environmental changes and at different life stages. We participate in several research projects where we develop basic scientific knowledge, and applies the basic research in the development of alternative and sustainable fish feed and new sustainable systems for marine aquaculture. The group has leadership roles in one of the university's six flagship centers, SWEMARC. Our focus species are currently mainly salmonids and wolffish.
