Whether gill area constrains fish metabolism through oxygen limitation is a debated topic. Here, the authors provide insights into this question by analysing mass-specific metabolic rates across 44 teleost fishes extracted from FishBase. They explore whether species deviations from metabolic rates predicted by body mass can be explained by species gill area. They show that the gill area explains c. 26%-28% of species-level deviations from mass-specific metabolic rates. Their findings suggest that gill area might indeed be one of the factors limiting metabolic rate in fishes.
鳃面积是否通过氧气限制来制约鱼类的新陈代谢是一个存在争议的话题。在此，作者们通过分析从鱼类数据库（FishBase）提取的44种硬骨鱼的单位体重代谢率，对这个问题提供了见解。他们探究了物种与根据体重预测的代谢率之间的偏差是否可以用物种的鳃面积来解释。他们表明，鳃面积解释了约26%-28%的物种水平上单位体重代谢率的偏差。他们的研究结果表明，鳃面积可能确实是限制鱼类代谢率的因素之一。
