Among juvenile Atlantic salmon Salmo salar either being fed ad libitum throughout a 3 month experiment or deprived of food in the middle month, food deprivation led to a decrease in SMR, which increased again once food was supplied ad libitum again. While the rank order of SMR among fish fed throughout remained relatively stable, that within the deprived group was inconsistent, suggesting that individual fish vary in their ability to reduce metabolic costs when food availability is low.
