... respirometry to measure AS at, above (+2.5°C) and below (–2.5°C) the self-selected, preferred temperature ( T pref ) of individual zebrafish ( Danio rerio ). AS was greatest 2.5°C above T pref , which was driven by an increase in maximal metabolic rate. This mismatch between T pref and the optimal temperature...
