✦ Synopsis

Routine oyxgen consumption (902) 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. vffO 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 ~rO 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.
