The aurora trout, Salvelinus fontinalis timagamiensis, is a variant or subspecies of the brook trout native to two lakes in the Temagami District of Ontario, Canada. The aurora trout is distinguished from the brook trout by its unique coloration. Aurora trout are generally without spots, the colouration grading from a magenta hue on the back to a bright, nearly fluorescent orange along the belly, especially in mature males. Adults average about 0.5 to 1.5 kg, although individuals up to 4 kg are known.
