Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; demersal; depth range 50 - 170 m (Ref. 2058), usually 50 - 70 m (Ref. 2058). Boreal
Asia: Lake Baikal and small lakes in its basins; lower Selenge, Angara and Baingol rivers.
Length at first maturity / Size / Weight / Age
Maturity: Lm 5.8 range ? - ? cm
Max length : 14.0 cm TL male/unsexed; (Ref. 2058)
Occurs where the bottom is sand, sand-and-stone and sand-and-silt. Stays at a depth range of 3-15 m during the winter months. Spawns from mid May until the end of June, over sand and stone bottom, 3-5 m depth, as well as in shallow inlets and tributary mouths. Eggs are deposited under stones and are guarded by the male. Males are larger than females. (Ref. 2058).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00794 (0.00389 - 0.01621), b=3.12 (2.95 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.3 se; based on diet studies.
Generation time: 4.8 ( 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 (tm=2; tmax=6; K=0.23).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
