Northern Blacknose Shiner 

 (Notropis heterolepsis beterolepsis)

 slender, and with a black band running around the snout above 

 the mouth, rather than through the chin. 



Size. About 70 mm. long. 



Habitat. In weedy streams and ponds and in shoals of the 

 Great Lakes. 



Food. Small crustaceans, insects, and plant material. 



This species is common and relatively hardy. 



Central Stoneroller Minnow 

 (Campostovia anomalum pnllum) 



Appearance. A spindle shaped fish with a deep groove between 

 the lower jaw and the fleshy lip. The color is olive brown above, 

 with brassy glints; the sides are blotched with black, with a dark 

 bar behind the gill cover; the belly is satin white. The males have 

 a dark bar across the dorsal and anal fins and a vertical bar at the 

 base of the tail fin, very conspicuous in the breeding season. The 

 male is distinctly humpbacked and has fleshy lips that make him 

 look like the endman in a Negro minstrel show. The snout and 

 whole body of the male become covered with short spines during 

 the breeding season. Young fish may be pinkish or magenta color. 

 Within this fish is hidden a peculiarity which is a positive iden- 

 tification — the long coils of the intestine are spirally wound around 

 the air bladder. 



Size. Length of adult males 150 mm.; of adult females about 

 125 mm.
