. The influence of feeding intensity (food per fish per unit time) on food intake, growth rate and size variation in groups of Atlantic salmon, Salmo salar L., under realistic rearing conditions was investigated. Feeding intensity influenced the pattern of food intake, but daily food intake, growth rate and size variation were negligibly affected, both when the fish were fed to satiation and when they were kept on restricted rations. Food intake in a meal varied considerably. It was negatively correlated with the amount consumed in the previous meal and positively correlated with the time since the previous meal. The overall conclusion, was that feeding intensity per se has no major influence on the profitability of cage‐rearing of salmon.
