Arctic Char

Salvelinus alpinus

Also known as Arctic Charr, Alpine Trout, Alpine Charr, Ikaluk

Arctic char are remarkably adaptable cold-water salmonids, renowned as the world's northernmost freshwater fish. Landlocked populations inhabit deep, icy lakes year-round, while anadromous runs migrate to marine coastal waters each summer to feed before returning to rivers to spawn. During autumn spawning, adults transform dramatically, developing brilliant fiery red bellies and vivid white margins along their lower fins.
