Asia: Endemic to Siberia. Known from the Ob to the Yana rivers.

Length at first maturity / Size / Weight / Age

Maturity: L_m 9.1, range 8 - 9.8 cm
Max length : 20.0 cm TL male/unsexed; (Ref. 593); common length : 11.0 cm FL male/unsexed; (Ref. 593); common length :11 cm FL (female)

Never enters the sea (Ref. 26334, 593). Spawning occurs in September and October (water temperature 4-8°C). Maturity is attained in second or third year of life. Both migratory and non-migratory populations exist. (Ref. 593).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00562 (0.00359 - 0.00881), b=3.28 (3.15 - 3.41), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.3 se; based on size and trophs of closest relatives

Generation time: 3.7 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (33 of 100).
