    Food Comments
    Eats aquatic and terrestrial insects and their larvae, crustaceans (especially crayfish), molluscs, fishes, and other animals. In streams, young feed mainly on aquatic and terrestrial drift invertebrates; in lakes, they feed on zooplankton and benthic invertebrates (Sublette et al. 1990). Large adults feed on fishes, crayfish, and other benthic invertebrates.
    Reproduction Comments
    Spawns in fall or early winter. Eggs hatch in 1-2 months, depending on temperature. Sexually mature in 2nd or 3rd year (or up to 5th year). Typically spawns in more than one year.
    Ecology Comments
    Preys on other species of trout and competes with them for food and space (Sublette et al. 1990).
