Adults inhabit a wide range of habitats, from rocky pools and riffles of headwaters to large lakes. They usually occur in small, clear, cool creeks and small to medium rivers. May be found at a depth greater than 45 m (Ref. 1998). They move to shallower water near sunrise and sunset to feed. Fry (1.2 cm in length) feed on plankton and other small invertebrates; bottom feeding commences upon reaching a length of 1.6-1.8 cm. Preyed upon by birds, fishes, lamprey, and mammals (Ref. 1998). Flesh is white, flaky, and sweet (Ref. 1998).
Adults home to certain gravelly spawning streams. Two to four males crowd around a female and press against her with their fins. Eggs are scattered and adhere to the gravel or are carried downstream and adhere to the substrate when the water is calmer. The spawning act lasts for 3-4 seconds and may occur 6-40 times an hour (Ref. 1998). Spent adults return to the lake 10-14 days after spawning began. Most females return to the lake during the first half of the downstream migration followed by most males in the latter half. Downstream fry migration occurs between dusk and dawn (Ref. 10928).
