Utbredning Territorier | FAO områden | Ekosystem | Förekomster | Prickkarta | Utplanteringar | Faunafri

Arctic to North Pacific: Chemulpo in North Korea (Yellow Sea) in the southwest to Sitka, Alaska in the southeast. Beyond the Bering Strait from Cape Lisburne in Chukchi Sea and east to Dease Strait (south coast of Victoria Island). Precise delimitation of the range depends on additional taxonomic study.

Kort beskrivning Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 44 - 59; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 39 - 47; Ryggkotor: 57 - 64. Distinguished by the presence of 3 dorsal and 2 anal fins, a lower jaw that is shorter than the upper, a chin barbel that is no longer than half the eye diameter, and a space between the second and third dorsal fins that is equal to or longer than the eye diameter (Ref. 27547). Lateral line curved in front, ending under the second dorsal fin (Ref. 27547); head with no lateral line pores (Ref. 1371). Expanded parapophyses swollen and hollow, beginning on about the vertebral centrum 9 or 10, containing outpouchings of the swim bladder (Ref. 1371). Second pelvic ray produced; caudal truncate or slightly emarginate (Ref. 27547). Grayish brown above, upper part of sides paler, sometimes with a silvery-violet shading, often mottled with indistinct darker blotches; lower sides and belly yellowish to silver white; fins dusky, dorsal and caudal with white edges (Ref. 27547).
Body shape (shape guide): fusiform / normal; Cross section: oval.

Biologi     Ordlista (t.ex. epibenthic)

Adults occur in shallow coastal waters (Ref. 1371). They enter rivers and may go considerable distances upstream, but usually remaining within regions of tidal influence (Ref. 1371, 27547). Adults exhibit seasonal movements: inshore during winter for purposes of spawning and offshore during summer for feeding (Ref. 1371). Juveniles and adults are opportunistic epibenthic feeders; juveniles feed on fish and small benthic crustaceans (Ref. 1371). Taxonomic problems to be solved.

Livscykel och parningsbeteende Könsmognad | Reproduktion | Lek | Ägg | Fekunditet | Larver

Spawns 5-7 times in its life, or even 9-10 times for those living 10-14 years. Fecundity varies with geographical region. It decreases from east to west in the European Arctic and from south to north in western Pacific waters. Throughout its distribution area, spawning occurs during January-February in coastal zones of bays and inlets on sand-gravel substrate and in strong tidal currents.
