Pygmy Whitefish

Fresh Water
Pygmy Whitefish (Prosopium coulteri) are a native salmonid in northwestern Montana. They seldom exceed 15.2 to 20.3 cm (6 to 8 in.) in length. Their overall appearance is silvery or white, except for an olive-brown back. The snout overhangs the mouth, the jaw lacks visible teeth, there is a single flap between the nostrils on each side, the eye is large (about the same diameter as the snout length), the transparent membrane surrounding the eye has a distinct notch below the rear edge of the pupil. The body is round in cross-section, the scales relatively large, with 54 to 79 along the lateral line, 31 to 40 around the body, and 16 to 20 around the caudal peduncle (Brown 1971, Page and Burr 1991, Holton and Johnson 1996).
