It is original of North America and distributed in the north of Canada and Alaska until the Nueva south England in the U.S.A. and the river basin of the Great Lakes . It has been introduced in many other areas of North America , causing, by its characteristics of pregiver piscívoro, considerable impacts on other native species, like the Cutthroat, and consequently to terrestrial species associated like the bears and eagles that fed themselves on this one.

In Argentina its introduction has only been successful in the river basin of the Argentine lake, although its presence also in the Burmeister lake has been registered recently in the Brown Skillful PN. In Argentine lake it has reached remarkable developments. A unit of 25 kgs was fished., closely together of the world-wide record of 29.5 of a Canadian lake.

It appreciates the deep and cold lakes, and limits his movements the atmosphere where it lives, without making migrations and feeding themselves and laying eggs in the lakes.

In spite of the sizes that reach is not a species so appreciated as other salmónidos, by its characteristics of poor combat efficiency. A hybrid form called Splake exists, product of crosses of this species and the stream trout (Salvelinus fontinalis), that reunites attractive conditions but and has been widely distribuída in the U.S.A. with piscicultura aid.
