Physiological seawater adaptation in juvenile Atlantic salmon (Salmo salar) autumn migrants
1. About 25 % of juvenile Atlantic salmon (Salmo salar) migrating downstream in the River Frome in southern England do so in the autumn rather than in the spring. Here, we examine the physiological status of these fish with regard to those features that adapt them to sea water during the parr–smolt...
