TLDR
It is the intention of this paper to encourage transparency and accuracy in future studies that measure the aerobic metabolism of fishes, and to highlight the fundamental issues with assuming broad relevance of the OCLTT hypothesis.Abstract:
Measurements of aerobic scope [the difference between minimum and maximum oxygen consumption rate (![Graphic][1] and ![Graphic][2] , respectively)] are increasing in prevalence as a tool to address questions relating to fish ecology and the effects of climate change. However, there are underlying issues regarding the array of methods used to measure aerobic scope across studies and species. In an attempt to enhance quality control before the diversity of issues becomes too great to remedy, this paper outlines common techniques and pitfalls associated with measurements of ![Graphic][3] , ![Graphic][4] and aerobic scope across species and under different experimental conditions. Additionally, we provide a brief critique of the oxygen- and capacity-limited thermal tolerance (OCLTT) hypothesis, a concept that is intricately dependent on aerobic scope measurements and is spreading wildly throughout the literature despite little evidence for its general applicability. It is the intention of this paper to encourage transparency and accuracy in future studies that measure the aerobic metabolism of fishes, and to highlight the fundamental issues with assuming broad relevance of the OCLTT hypothesis.

TL;DR: The negative effects of climate change cannot be adequately anticipated or prepared for unless species responses are explicitly included in decision-making and global strategic frameworks, and feedbacks on climate itself are documented.

The effects of temperature on aerobic metabolism: towards a mechanistic understanding of the responses of ectotherms to a changing environment
TL;DR: A view of why current theories provide an inadequate mechanistic account of the effects of temperature on aerobic metabolic processes across levels of organization from individual proteins to intact animals is presented.
Journal ArticleDOI
The determination of standard metabolic rate in fishes.
TL;DR: The main objective was to compare eight methods to estimate SMR and show that 12 h is insufficient but 24 h is adequate, and a list of basic recommendations for practitioners who use respirometry to measure SMR in fishes is provided.

Physiological impacts of elevated carbon dioxide and ocean acidification on fish
Rachael M. Heuer,Martin Grosell +1 more
TL;DR: The present review presents a clear message that ocean acidification may cause significant effects on fish across multiple physiological systems, suggesting that pH compensation does not necessarily confer tolerance as downstream consequences and tradeoffs occur.

Measurement and relevance of maximum metabolic rate in fishes.
Tommy Norin,Timothy Clark +1 more
TL;DR: Various techniques used to elicit and measure maximum (aerobic) metabolic rate in different fish species with contrasting lifestyles are outlined and the relevance of MMR to the ecology, fitness and climate change resilience of fishes is discussed.

TL;DR: The conceptual analysis suggests that the relationships between energy turnover, the capacities of activity and other functions and the width of thermal windows may lead to an integrative understanding of specialization on climate and, as a thermal matrix, of sensitivity to climate change and the factors involved.

TL;DR: It is concluded that a mechanism of behavioral thermoregulation has evolved which favorably balances daily metabolic expenditures in order to conserve energy when food is limited.
