Abstract

The logarithm of the amount of oxygen consumed per unit swimming velocity in meters per minute for steadily swimming antarctic fishes at freezing temperatures is of the same order as the rate for temperate species at their lower temperature ranges. In contrast to temperate fishes, the antarctic fishes have their greatest swimming activity around -1.8°C and a level of no excess activity at about +2°C.
