Behaviour

The anadromous form of Arctic Char migrates into the sea in the summer to feed, but returns to fresh water to pass the winter. The non-anadromous form remains in fresh water throughout its entire life. It spawns in fall and early winter on near-shore shoals of lakes and the gravel bottoms of streams and rivers. Arctic Char don't die after spawning like other types of salmon and will spawn several times throughout their lives.
