Korte beschrijving Morfologie | Morfometrie

Dorsale stekels (totaal): 0; Dorsale zachte stralen (totaal): 11-13; Anale stekels 0; Anale zachte stralen: 10 - 14; Wervels: 58 - 63. Distinguished by the gill rakers that are longer than 20% of the interorbital width, 19 to 25 gill rakers (with modal counts of 22 or 23), and a pronounced hump behind the head in adults (Ref. 27547). Adipose fin well developed, often larger in males; axillary process present in pelvic fins (Ref. 27547). Dark brown to midnight blue above fading to silver on sides and wide beneath; no parr marks in young (Ref. 27547).

Inhabits coastal waters near shore (Ref. 5723), lower reaches of rivers with slow current, large lakes with tributaries, floodplain lakes, deltas and estuaries, brackish waters (Ref. 59043). Migrates up to more than 1,200 km inland for spawning (Ref. 5723). Overwinters near river mouths (Ref. 5723). There are non-migratory freshwater populations. Adults feed mostly on mollusks, crustaceans and chironomid larvae (Ref. 28219).

Levenscyclus en paargedrag Maturiteit | Voortplanting | Paaien | Eieren | Fecunditeit | Larven

Upstream spawning migrations may be extensive but some populations seldom venture far upstream and still others may never go to sea at all (Ref. 593). Mature adults migrate upstream as early as June to spawn in October. It is assumed that the young hatch in late winter and spring, subsequently moving downstream, to return as mature adults 4 to 6 years later (Ref. 27547).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00550 (0.00331 - 0.00911), b=3.24 (3.10 - 3.38), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.3 ±0.2 se; based on diet studies.

Weerstandsvermogen (Ref. 120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (tm=3-14; tmax=14; Fec=8,000).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (52 of 100).

Prijsklasse (Ref. 80766): Very high.
