Mountain Whitefish Fishing in Idaho

A native salmonid of cold, clear Western rivers and mountain lakes, with silver sides, large scales, an adipose fin and a small mouth under the snout. Whitefish eat insect larvae, insects, fish eggs and small fish, and feed most actively in winter, when many anglers seek them. They take nymphs and small flies, and the weak mouth calls for a gentle hook set.
