It is native to Eastern North America in the United States and Canada, but has also been artificially introduced elsewhere in North America and to other continents. In parts of its range, it is also known as the eastern brook trout, speckled trout, brook charr, squaretail, or mud trout, among others.〔(Common names of ''Salvelinus fontinalis'' ) FishBase, retrieved 22 May 2015〕 A potamodromous population in Lake Superior is known as coaster trout or, simply, as coasters. The brook trout is the state fish of nine states: Michigan, New Hampshire, New Jersey, New York, North Carolina, Pennsylvania, Vermont, Virginia, and West Virginia. ==Systematics and taxonomy== The brook trout was first scientifically described as ''Salmo fontinalis'' by the naturalist Samuel Latham Mitchill in 1814. The specific epithet "''fontinalis''" comes from the Latin for "of a spring or fountain", in reference to the clear, cold streams and ponds in its native habitat. The species was later moved to the char genus ''Salvelinus''. Though commonly called a trout, the brook trout is thus actually one of the chars, which in North America also include the lake trout, bull trout, Dolly Varden, and the Arctic char. There is little recognised systematic substructure in the brook trout, but two subspecies have been proposed. On the other hand, three ecological forms are distinguished.d 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Brook trout」の詳細全文を読む スポンサード リンク
