Steffensen Fish Lab

Our research concentrate on comparative respiratory and circulatory physiology of fish, ranging from questions concerning metabolic cold adaptation in Arctic and Antarctic fish, to possible benefits and problems for fish swimming in schools.

In addition we are studying problems related to improving growth of fish in aquaculture, the adaptation of fish to environmental hypoxia and temperature, metabolism and kinematics of swimming fish, and the form and function of the primary and secondary circulatory systems in teleosts.
