1. 从空气和水中的氧气吸收量已被测量与非洲肺鱼的重量有关。从空气和水中摄取的氧气总量从3-7克样品中的60毫升O2kg-1 h-1 STPD到255克样品中的30毫升O2kg-1 h-1。3. 在研究的体重范围内，水体的总氧吸收量变化了2倍，而在相同的体重范围内，水体的氧吸收量变化了8倍。较小的鱼通过水生呼吸满足70%的氧气需求，而成年鱼则为10-15%。4. 讨论了水陆两栖的双峰呼吸模式与该物种的自然栖息地的关系。
1. Oxygen uptakes from air and water have been measured in relation to weight of the African lungfish Protopterus amphibius Peters. 2. Combined O2 uptake from air and water ranged from 60 ml O2 kg-1 h-1 STPD, in a 3-7 g specimen, to 30 ml O2kg-1 h-1, in a 255 g specimen. 3. While the combined O2 uptake changed by a factor of 2, within the weight range under study, the aquatic O2 uptake changed 8-fold within the same range. The smaller fish satisfy 70% of their O2 requirement by aquatic breathing compared to 10-15% in the grown specimens. 4. The pattern of bimodal breathing in P. amphibius is discussed in relation to the natural habitat of the species.
