John Fleng Steffensen is Professor at University of Copenhagen, Marine Biological Section, Department of Biology. His research concentrates on comparative respiratory and circulatory physiology of fish, ranging from questions concerning metabolic cold adaptation in Arctic and Antarctic fish. In addition he is 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.
Further information concerning:
1. The form and function of the primary and secondary circulatory systems in teleosts, 2. The adaptation of fish to environmental hypoxia and temperature, including temperature preference, 3. Metabolism, kinematics and muscle dynamics, and circulation of swimming fish - mainly in carangiforms but also labriform
4. Projects physiological performance, tolerance and growth of fish in aquaculture, particularly sturgeon, eel, tilapia and trout.
