Οικολογία του Salvelinus malma

Κύρια Αναφ.	Scott, W.B. and E.J. Crossman, 1973
Σχόλια	Occurs 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 (Ref. 1998).
