Kort beskrivning Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 10 - 12; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 12 - 14; Ryggkotor: 64 - 67. Distinguished by the pale or colorless pelvic fins, a terminal mouth and the presence of 41 to 48 gill rakers on the 1st gill arch (Ref. 27547). Dorsal fairly high and slightly falcate; pelvic with axillary process (Ref. 27547). Brown to dark greenish above fading to silvery on sides and belly; fins pale (Ref. 27547).
Body shape (shape guide): fusiform / normal.

Biologi     Ordlista (t.ex. epibenthic)

Adults occur in brackish waters (20-22 ppt) of coastal lagoons and mouths of rivers and bays (Ref. 4779, 59043). Nerito-pelagic (Ref. 58426). Food consists of small crustaceans, insects, small fishes (Ref. 28219, 28857), worms and clams (Ref. 58426, 59043). No feeding occurs during the upstream migration (Ref. 4779). Lives 10 -12 years, rarely up to 20 (Ref. 59043). Mature individuals enter rivers in shoals to spawn (Ref. 4779). They spend 6-8 years at sea before maturing and returning to rivers in June - July, to spawn in September - October of same year. A second run in autumn; those fishes remain a year in rivers before spawning. They move far upstream, sometimes up to 1500 km, spawn in shallow tributaries with some current in well oxygenated water over gravel bottom. Individual females do not spawn every year; only 2-3 times during entire life. After spawning adults return directly to sea. Embryonic development lasts up to 7 months. Alevins migrate downstream in May - June (Ref. 59043). Collected by fyke nets (Ref. 4526). An important commercial species but catches and abundance are markedly reduced in recent years (Ref. 59043).

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

Mature adults migrate upstream in the summer and may cover as much as 1,000 km (Ref. 28219) to spawn over gravel in fairly swift water. After spawning, adults return downstream. Young probably hatch in the spring and descend rivers into estuaries (Ref. 27547). Coregonus autumnalis do not breed yearly (Ref. 28219, 28220).
