Lake trout is a freshwater char living mainly in lakes in northern North America. Lake trout are prized both as game fish and as food fish.
Lake trout are the largest of the trouts, the record weighing almost 46.3 kg (102 lb). They were fished commercially in the Great Lakes until lampreys, overharvest and pollution extirpated or severely reduced the stocks. Commercial fisheries still exist in some smaller lakes in northern Canada.
Lake trout are dependent on cold, oxygen-rich waters. They are pelagic during the period of summer stratification in dimictic lakes, often living at depths of 20–60 m (60–200 ft).
The Lake Trout goes by other names such as mackinaw, lake char (or charr), touladi, togue, grey trout, siscowet, paperbellies, leans.
