Long-distance anadromous migration in a fresh water specialist: the Lake Trout (Salvelinus namaycush)
The Lake Trout, Salvelinus namaycush, is believed to be one of the most saline intolerant salmonid species, typically completing its life wholly in fresh water. Historical observations and more recent quantitative assessments have shown, however, that in some Arctic populations, Lake Trout can migra...
