The aerobic scope of an antarctic fish, Pagothenia borchgrevinki and its significance for metabolic cold adaptation
Resting weight-specific oxygen consumption of the cryopelagic Antarctic nototheniid Pagothenia borchgrevinki at 0°C was 39.6 ml kg-1 · h-1 for a 50 g fish, with oxygen consumption being described by the regression equation: log10 VO2(ml/h)=-1.104+0.825 log10 Mb (g). These values are considerably bel...
