Notizen: Summary Routine oyxgen consumption ( $$\dot VO_2$$ ) of the artedidraconid fish Pogonophryne scotti at-1°C is determined using a flow-through respirometer. The metabolic rate during an 8 to 12 h acclimation period is found to exceed the actual routine metabolic level by a factor of 2 to 4. $$\dot VO_2$$ of 7 P. scotti varies between 2.5 mg/h and 4.4 mg/h for fish weighing 58 g to 210 g. The exponent of the oxygen consumption/weight equation is 0.46. From this relation, routine $$\dot VO_2$$ of a 100 g fish is calculated as 2.9 mg/h. The significance of acclimation times and the use of standardized methods for future respiration measurements of Antarctic fish are discussed.
