Park Species Detail: Britt, 1993: Notropis rubellus, rosyface shiner (resident, native). The rosyface shiner occurs in eastern and central North America, from New York south to Virginia in the east, and to Kansas and Oklahoma in the west. They occur north to Wisconsin and southern Canada in the Mississippi River basin. They generally prefer flowing water of streams and rivers, rather than lakes or ponds. They occur in the lower portions of streams, especially areas over fine gravel or sand. They are intolerant of high turbidity and reductions iil their populations and range have been associated with increased turbidity. Their diet consists of aquatic insects, algae and inorganic material. The adult size is 70-75 mm (fL), and they live for at least 3 years, with females achieving 3 years more often than males. Spawning occurs in the spring from the end of May into June at ambient water temperatures 68-72 of. Females produce 450-1500 eggs depending on age and spawn in groups of other males and females. Eggs hatch in 57-59 hours at ambient water temperature of about 70°F. Eggs average 1.5 mm in diameter. There have been some instances of hermaphrodism in 2 year old. The rosyface shiner has not been collected in recent studies., Park Species Data Source: Britt et al 1993.
