Thermal performance measures for juvenile Atlantic salmon (S. salar) obtained using the PW Doppler echocardiography

Measure	Mean
TAB (°C)	15.7 ± 0.6
TArr (°C)	25.0 ± 0.4
TpeakfH (°C)	23.8 ± 0.3
TpeakSD (°C)	11.5 ± 0.3
TpeakCO (°C)	20.9 ± 1.5

Note: T_AB, Arrhenius breakpoint temperature; T_Arr, temperature at onset of cardiac arrhythmias; T_peakfH, temperature for peak f_Hmax; T_peakSD, temperature for peak stroke distance; T_peakCO, temperature for peak cardiac output.

Data presented as means ± SEM. N = 8.
