Smolts may also prefer to swim at depths providing the most efficient use of energy either for movements or physiological processes. 2; Rikardsen & Dempson 2011 [Chapter 5]). Atlantic salmon are distributed over large areas of the Atlantic Ocean and undertake long sea migrations. They have been captured in the Norwegian Sea, north of the Faroe Islands, in the Labrador Sea and in the Arctic Ocean, including the North Greenland Sea and the Barents Sea (Hansen & Quinn 1998; Holm et al. 2000, 2003; Rikardsen et al.

However, it is not known to what extent individuals reside in the same ocean area during their time at sea, or whether they cover large areas. 1 Returning from ocean feeding grounds and entering the rivers The sea age when Atlantic salmon first become sexually mature and return to their home river for spawning depends on genetics as well as on growing conditions at sea, but the Aquatic Nomads: The Life and Migrations of the Atlantic Salmon 13 proximate factors initiating the homeward migration are unknown (Hansen & Quinn 1998).

4 body lengths s−1, were reported for larger salmon (75–85 cm body length) by Beamish (1978). Maximum swimming speeds in nature are likely to be higher than those recorded under laboratory conditions. 5 m s−1, and it is not unlikely that Atlantic salmon may also be able to obtain speeds up to 10 body lengths s−1. Little is known about how high Atlantic salmon can jump. Physical conditions such as water depth and velocity beneath the obstruction are important for the maximum leaping capability (Stuart 1962).
