Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 0; Μαλακές ραχιαίες ακτίνες (συνολικά) : 42 - 57; Εδρικές άκανθες: 0; Μαλακές εδρικές ακτίνες: 33 - 44; Σπόνδυλοι: 49 - 57. Caudal fin deeply concave. Lower jaw slightly longer than upper jaw. Chin barbel very small. No lateral line pores on head. Scales small and embedded, not overlapping. Brownish along the back with many fine points; the sides and belly silvery; the fins dusky with pale margins (Ref. 1371).
Body shape (shape guide): elongated; Cross section: oval.
Occurs in coastal habitats during summer and winter (Ref. 1371). Cryopelagic or epontic, from surface down to 1383 m (Ref. 58426). In the Beaufort Sea, it may also be found in brackish lagoons and in almost fresh water in river mouths (Ref. 1371). Although associated with the occurrence of ice (White Sea), it is present in ice-free near-shore waters (Alaska) (Ref. 1371). Onshore-offshore movements are associated with spawning and movements of the ice (Ref. 27547). Feeds mostly on epibenthic mysids, also amphipods, copepods and fishes (Ref. 1371). Also caught with mid-water trawls (Ref. 1371). Utilized as fishmeal and source of oil (Ref. 1371). Euryhaline and eurythermic.
Oviparous, sexes are separate (Ref. 101194). Fish move close inshore, often in large numbers to spawn (Ref. 27547).
