Cardiorespiratory metrics of cobia during and following a Ucrit trial upon a 3 wk exposure to either ambient or elevated pCO2

This study examined cardiac and swimming performance during a maximum sustained swimming trial (Ucrit) of cobia (Rachycentron canadum) following a three-week exposure to either elevated (~1,600 µAtm) or ambient (~500 µAtm) pCO₂. This dataset encompasses cardiac variables (stroke volume, heart rate, and cardiac output) during swimming and recovery from a Ucrit trial, hematological variables (hemoglobin, hematocrit, mean corpuscular hemoglobin concentration) following the swimming test and hour long recovery, oxygen consumption variables (MO₂ min, MO₂ max, aerobic scope, and factorial aerobic scope) during and following the swimming test.
