No studies have examined the effects of cold temperatures (∼0–1 °C) on in vivo cardiac function and control, and metabolism, in salmonids. Thus, we examined: 1) how acclimation to 8 °C vs. acclimation (>3 weeks) or acute exposure (8-1 °C at 1 °C h(−1)) to 1 °C influenced cardiorespiratory paramet...
