Large fish develop respiratory distress more quickly in warm water than smaller species, according to a new study involving researchers at Radboud University in collaboration with international researchers from McGill University (Canada) and the University of Montana (U.S.). This means that ocean warming triggered by climate change will have an impact on the respiratory physiology of larger fish, which may eventually affect physiological performance, survival and size-structure of fish populations. The researchers have come to this conclusion with the aid of a new model that can more accurately calculate the effect of body temperature, activity and size on oxygen uptake. Their findings will be published in PNAS in the week of 30 November.
