Fish may fight rather than feed in a novel environment: metabolic rate and feeding motivation in juvenile Atlantic salmon
This study tested the hypothesis that juvenile Atlantic salmon Salmo salar with a high resting metabolic rate and probability of dominance will also have a correspondingly higher feeding motivation in a novel environment to offset their greater costs of maintenance. The opposite was found to be the...

This study tested the hypothesis that juvenile Atlantic salmon Salmo salar with a high resting metabolic rate and probability of dominance will also have a correspondingly higher feeding motivation in a novel environment to offset their greater costs of maintenance.
