The maximum aerobic metabolic rate (MMR) of fish sets an upper limit on their ability to perform physiological functions associated with physical activity, growth, and reproduction. While there is increasing interest in the significance of MMR for the ecology of fish, and particularly their ability to cope with climate change, there are currently two main methods used to estimate MMR (namely, measuring oxygen uptake either DURING and AFTER inense exercise) with a limited understanding of whether these methods give differing results. In a new meta-analysis of literature data for 121 fish species, Shaun Killen, Tommy Norin and Lewis Halsey find that these methods tend to give similar estimates for MMR within and among species.
