Hatchery reared Atlantic salmon ( Salmo salar L.) parr were tagged with the standard I.C.E.S./I.C.N.A.F. salmon tag at water temperatures of 15°C and 6°C. They were then subjected to swimming trials in a tunnel respirometer. Following this treatment the 15°C fish developed necrotic infarcts around the tag insertions. Provided they did not become infected these lesions healed, but if the fish were retested 9 days later, the wound enlarged, became extremely inflamed, and the fish died soon after. This effect was not seen in 6°C fish.
