This data set contains physiological responses of juvenile spiny damselfish from an experiment which investigated the effects of stable and diel-cycling elevated CO2 and temperature on the juvenile stage of a coral reef fish. The physiological metrics consisted of metabolic traits, i.e. resting and maximal oxygen uptake rates, and aerobic scope, and were measured using an intermittent flow respirometry system. The experiments were conducted at the National Sea Simulator (SeaSim) facility at the Australian Institute of Marine Science (AIMS) (Cape Cleveland, Australia). The fish were collected in July 2015 and experiments were conducted in April - November 2017.
The full methodology is available in the accompanying publication, "Beneficial effects of diel CO2 cycles on reef fish metabolic performance are diminished under elevated temperature".
