Biologi     Daftar kata (contoh epibenthic)

Inhabits ocean and coastal streams. Migrating fry form schools in estuaries, remain close to shore for a few months and finally disperse to enter the sea (Ref. 1998). Epipelagic (Ref. 58426). Juveniles and adults feed mainly on copepods, tunicates and euphausiids but also on pteropods, squid and small fishes (Ref. 1998). Adults cease feeding in freshwater (Ref. 1998). Males and females die after spawning. The catch is mostly canned but also sold fresh, dried-salted, smoked, and frozen. Eaten steamed, fried, broiled, boiled, microwaved, and baked (Ref. 9988). Utilized for caviar. The Alaska Salmon fishery of this species has been certified by the Marine Stewardship Council (http://www.msc.org/) as well-managed and sustainable (http://www.msc.org/html/content_485.htm).
