    Formal Taxonomy
    Animalia - Craniata - Actinopterygii - Cypriniformes - Cyprinidae - Rhinichthys - . However, as a result of multiple hybridizations, populations are self-perpetuating and reproductively independent of the parental species and so have been recently recognized as a distinct species (Haas 2001). Some upstream populations such as those in the Kettle River of British Columbia and Washington State are isolated from lower Columbia River populations and may represent different species (Hughes and Peden 1988; McPhail, pers. comm., 1991).

    Food Comments
    Food preferences unknown, but the closely-related R. OSCULUS is a bottom feeder. Young R. OSCULUS are primarily planktivores and adults feed mainly on aquatic insects, freshwater shrimp, plant material and zooplankton (Wydoski and Whitney 1979).
    Reproduction Comments
    Reproductive biology has not been investigated. Breeding probably occurs in late spring and summer if similar to that of congeners R. FALCATUS, R. CATARACTAE and R. OSCULUS (Scott and Crossman 1973, Peden and Hughes 1981).

    Global Range
    Columbia River drainage, British Columbia, Idaho, Washington, and Oregon; common (Page and Burr 1991). The species is known from the type locality of the Columbia River at Umatilla, Oregon, and from scattered localities throughout the Columbia drainage below the Arrow Lakes, Slocan Lake, and Kootenay Lake. In Canada, the species has a patchy distribution in the Columbia, Kootenay, Slocan, Kettle, and Similkameen rivers, and it is present in the lower Pend d'Oreille and Mission Creek (C. Wilhelmson, draft COSEWIC report, 2003). It may occur in rivers of northern Oregon and the Idaho portion of the Snake River, but inventories are needed to determine this (Hughes and Peden 1988, McPhail 1990).
