The oxygen consumption rates (VO2) of 9 albacore tuna, Thunnus alalunga (8.5-12 kg) were measured at sea in a swimming respirometer to determine the effects of relative swimming velocity, ambient O2 tension, and water temperature. Significant positive relationships were obtained between tail-beat frequency and relative speed and between relative speed and VO2. The albacore metabolic rate was not appreciably affected by exposure to water temperatures ranging from 13.5 degrees to 16.9 degrees C. Brief exposure to hyperoxia (200-400 mmHg), which was done to reduce the initial stress upon fish in the respirometer, did not affect VO2. Hypoxia (50-99 mmHg), however, did tend to reduce VO2 and affect swimming velocity.
在游泳呼吸仪中于海上测量了9条长鳍金枪鱼（Thunnus alalunga，体重8.5 - 12千克）的耗氧率（VO2），以确定相对游泳速度、环境氧气张力和水温的影响。尾鳍摆动频率与相对速度之间以及相对速度与VO2之间均呈现出显著的正相关关系。长鳍金枪鱼的代谢率在暴露于13.5摄氏度至16.9摄氏度的水温范围内时并未受到明显影响。为减轻呼吸仪中鱼类的初始应激而进行的短暂高氧暴露（200 - 400 mmHg）并未影响VO2。然而，低氧（50 - 99 mmHg）确实倾向于降低VO2并影响游泳速度。
