Arctic char

Arctic char or Arctic charr (Salvelinus alpinus) is a cold-water fish in the Salmonidae family, native to Arctic, sub-Arctic and alpine lakes and coastal waters. It breeds in fresh water, and populations can be either landlocked or anadromous, migrating to the sea. No other freshwater fish is found as far north. For instance, it is the only species of fish in Lake Hazen, on Ellesmere Island in the Canadian Arctic. It is one of the rarest fish species in Britain, found only in deep, cold, glacial lakes, mostly in Scotland, and is at risk from acidification. It is also found in deep mountain lakes in England, Ireland and Wales such as the Lake District. In other parts of its range, such as Scandinavia, it is much more common, and is fished extensively. It is also common in the Alps, (particularly in Trentino and in the mountain part of Lombardy), where it can be found in lakes up to an altitude of 2,600 m (8,500 ft) above sea level, and in Iceland. In Siberia, it is known as golets and it has been introduced in lakes where it sometimes threatens less hardy endemic species, such as the small-mouth char and the long-finned char in Elgygytgyn Lake.
