Habitats: (Type / Subtype / Dependence) |
|||||||||||
Global Habitat Comments: | Flowing pools and gravel runs of creeks and small to medium rivers; rocky margins of lakes (Page and Burr 1991). Usually found in slow-moving current. Usually in slower, deeper water than longnose dace (Wydoski and Whitney 1979). Breeding habitat probably is similar to that of other dace that spawn in riffles. | ||||||||||
Food Habits: |
Invertivore: Adult, Immature
|
||||||||||
Global Food Habits Comments: | Young-of-the-year feed mostly on dipterous larvae. Yearlings begin feeding on aquatic insect larvae (e.g., Ephemeroptera and Diptera); by September, they feed mostly on terrestrial insects. Adults eat aquatic insect larvae and terrestrial insects. | ||||||||||

Global Range Comment: | Fraser and Columbia river drainages, British Columbia, Oregon, Washington, and Idaho, but not above Shoshone Falls (Snake River, Idaho), Spokane Falls (Spokane River, Washington), and Albeni Falls (Pend Oreille River, Washington) (Lee et al. 1980). Widely distributed in British Columbia in numerous river drainages (Peden 1991). Generally uncommon (Page and Burr 1991). | ||||||||||
