How to identify a Mountain Whitefish
Like other salmonids, the mountain whitefish has an adipose fin and an axillary process. The mouth, however, is slightly subterminal with the snout extending clearly beyond it. The body is silvery overall. The back is brownish to olive. The scales often have pigmented borders, especially on the back. The ventral and pectoral fins may have an amber hue in adults. The body is nearly cylindrical, but not quite as cylindrical as the body of the round whitefish. It is nevertheless among the species referred to as “round whitefishes”, and is therefore distinguishable from the lake whitefish which has a laterally compressed body.
Where to catch Mountain Whitefish
The mountain whitefish is endemic to the lakes and streams of the northwestern United States and southwestern Canada, from the Lahontan basin in Nevada north to the southern border of the Yukon Territory. It occurs inland into Alberta in Canada and Wyoming in the United States. Its range overlaps that of the widespread lake whitefish in British Columbia and Alberta, and slightly overlaps that of the round whitefish in extreme northern British Columbia near the Yukon border.
