This study confirmed earlier evidence for a correlation between otolith increment width and resting metabolic rate in the absence of somatic growth in Atlantic salmon parr. However, increment width responded more conservatively to a change in temperature than did resting metabolic rate. Consequently, the study demonstrated that although increment width varied with temperature the process governing accretion rate was not simply related to resting metabolic rate.
