Arctic char is a cold-water fish in the salmon family, native to the Arctic and subarctic regions. It is widely noted as the most northerly freshwater fish species in the world.

What it is

Arctic char (Salvelinus alpinus) belongs to the salmon family Salmonidae, closely related to trout and salmon. Populations may be anadromous (migrating to sea) or landlocked in freshwater lakes, depending on local conditions.

Where it lives

This species has a circumpolar distribution across the Northern Hemisphere, including Arctic and subarctic waters of Canada, Europe, and Asia. It inhabits lakes, rivers, streams, and coastal marine waters, and is considered Canada's most northerly freshwater fish.

Why it matters

Arctic char are important in Arctic food webs and are harvested as a commercial food fish in some regions. Conservation concerns include overharvesting, climate change, and habitat alteration, making management key for sustainability.

In short

  • Most northerly freshwater fish species in the world.
  • Occurs in circumpolar Arctic and subarctic regions.
  • Can be anadromous or landlocked.
  • Important as a commercial food fish in Canada.
Canadian angle

Arctic char is especially relevant to Canada because it occurs widely in northern Canadian freshwater and coastal waters, including the territories and Atlantic regions, and is identified by Canadian sources as the country’s most northerly freshwater fish species.
