Endurance of farmed and sea‐ranched Atlantic salmon Salmo salar L. males was analysed during spawning time. The fish were endurance tested at different swimming speeds (1.6–2.1 m s −1 ) in forced swim trials. The sea‐ranched males (51‐65 cm, n = 20) fatigued significantly earlier than the farmed males(59‐72 cm, n = 20),although the sea‐ranched males were significantly smaller than the farmed males. When the size difference between the two groups were corrected for, no significant difference in the endurance of the two groups was found. Farmed salmon had a significant higher fat content in white muscle (4.7%) than sea‐ranched salmon (1.1%).
