Bear Lake Whitefish
Prosopium abyssicola
The Bear Lake whitefish, Prosopium abyssicola, is a salmonid fish endemic to Bear Lake on the Utah-Idaho border. It is one of three species of Prosopium endemic to Bear Lake, the other two being the Bonneville whitefish and the Bonneville cisco. The species is listed as a Wildlife Species of Concern by the Utah Division of Wildlife Resources.
In appearance it is very similar to the closely related Bonneville whitefish P. spilonotus. Generally whitish in color, it has more of a "Roman nose" than the Bonneville whitefish, and larger scales. It never has spots, while young Bonneville whitefish (up to 10 inches) have a pattern of spots. The Bear Lake whitefish tends to be smaller as well, rarely longer than 9 inches, and with a maximum known length of 11 inches.
