Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 11-13; Anal spines: 0; Anal soft rays: 10 - 14; Vertebrae: 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).

Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions | Faunafri

Arctic: Sweden and Finland to the extreme northeast of Siberia, in the western portion of the Bering Sea basin, and partly in the basin of the Sea of Okhotsk. In Alaska in the tributaries of the Beaufort, Chukchi, and Bering seas (Ref. 5723). Additional populations in Poland and in the Alps (Ref. 683). Appendix III of the Bern Convention (protected fauna). Belongs to Coregonus clupeaformis complex (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).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00695 (-0.10596 - 0.11987), b=3.16 (3.09 - 3.23), based on LWR estimates for species & genus-BS (Ref. 93245).

Trophic Level (Ref. 69278): 3.2 ±0.4 se; Based on diet studies.

Resilience (Ref. 69278): Low, minimum population doubling time 4.5 - 14 years (tm=3-14; tmax=14; Fec=8,000).

Vulnerability (Ref. 59153): High vulnerability (64 of 100) .

Price category (Ref. 80766): Very high.
