Decreased critical swimming speed and increased oxygen consumption () was found for externally tagged Atlantic cod Gadus morhua swimming at a high speed of 0·9 body length (total length, L T ) s −1 . No difference was found in the standard metabolic rate, indicating that the higher for tagged cod was due to drag force rather than increased costs to keep buoyancy.
