The O2 uptake capacity of Amphipnous cuchia has been determined in relation to standard temperature of 25 degrees C. The measurement of O2 uptake indicates nearly 75% of the oxygen demand to be met through the air breathing organs and 25% by the skin and vestigeal gill through water in a normal habitat. The total VO2 during aerial-aquatic gas exchange is 60.5 ml/kg/hr. The prevention of surfacing resulted in a lower O2 uptake rate (38.29 ml/kg/hr). During submergence, the utilisation of air sacs for extracting O2 by regular pumping of water in and out is peculiar to the fish. Under normal respiratory conditions (air + water), the slope for O2 uptake through air is 0.72, 0.23 for water and 0.57 for both air + water. The average ratio borne by the fish for aquatic/air breathing (ml/kg/min) is higher in fishes below 60 g body weight, and aquatic respiration predominates in fishes weighing less than 6.0 g.
已测定了库氏双须缺鳍鲶在25摄氏度标准温度下的耗氧能力。耗氧量的测量表明，在正常栖息地中，近75%的氧气需求通过呼吸空气的器官满足，25%通过皮肤和残余鳃从水中获取。气 - 水气体交换期间的总耗氧量为60.5毫升/千克/小时。阻止浮出水面会导致较低的耗氧率（38.29毫升/千克/小时）。在水下时，通过有规律地抽水进出气囊来提取氧气是这种鱼特有的行为。在正常呼吸条件下（空气 + 水），通过空气的耗氧斜率为0.72，通过水的为0.23，通过空气 + 水的为0.57。体重低于60克的鱼中，水生/空气呼吸的平均比例（毫升/千克/分钟）较高，体重小于6.0克的鱼中水生呼吸占主导。
