    Food Comments
    Young feed mainly on aquatic and terrestrial insects. Adults feed largely on diatoms that they ingest while scraping their specialized, chisel-like lower jaw along rocks or other substrate (Scott and Crossman 1973).
    Reproduction Comments
    In British Columbia, spawning occurs usually in late June-early July when water temperatures reach about 62.5 F or higher. Mean egg count for 6 females in Wolfe Lake, British Columbia, was 6200. Males probably mature at age 3, most females at 4. Individuals may live up to about 6 years.
