BiologyOccurs in deep runs and pools of creeks and rivers; also in lakes and the sea (Ref. 5723). Lives in very clean mountain streams (Ref. 12218). Nerito-pelagic (Ref. 58426). Typically anadromous, but many populations are landlocked (Ref. 5723). Anadromous fish may spend 2-3 years at sea, evidently near shore, and migrate upstream to spawn (Ref. 5723). Young remain in streams for 3-4 years and feed on insects, leeches, snails, and salmon eggs (Ref. 1998) before entering brackish and salt water to feed on insects, fishes, and other invertebrates. Utilized fresh and eaten fried, broiled, and baked (Ref. 9988).
