By definition, whitefish or white fish is a fisheries term for several species of demersal fish with fins, particularly:
*Atlantic cod (Gadus morhua),

Mountain whitefish common names include Rocky Mountain whitefish, mountain herring, peamouth, and the Yellowstone Rover whitefish.

Whitefish can be found anywhere in a river but are most abundant in deep pockets in moderately fast, oxygenate water.

Mountain whitefish is the most common whitefish species in the Northwest. It is generally considered a game fish by most states and is taken by hook and line, although often inadvertently while fishing for trout.

Whitefish are typically fall spawners. Mountain whitefish spawn during the fall (October through early December) when water temperature is less than 48 °F.
