Table 1.

Linear mixed-effects models for the influence of metabolic traits and swimming performance on time spent in the net during repeated simulated trawls. SMR, standard metabolic rate (mg O₂ h⁻¹); AS, aerobic scope (mg O₂ h⁻¹); EPOC, excess post-exercise oxygen consumption (anaerobic capacity; mg O₂); U_gt, gait transition speed (cm s⁻¹); U_max, maximum speed (cm s⁻¹).
