Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 6 - 7; Rückenflossenweichstrahlen (insgesamt) : 30 - 34; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 30 - 36. No swim bladder (Ref. 128162),

Adults prefer deep waters but females and occasionally males may be found on the surface. Depth of distribution in January and February is 150-250 m; 100-120 m in March and April. Adults feed mainly on the amphipod Macrohectopus branickii. Mature individuals spawn in July to October. Fat content of the body is about 25%. The dead fish does not sink but float up to the surface and freeze into ice. In spring, they are cast ashore by the waves (Ref. 26334).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00550 (0.00324 - 0.00932), b=3.14 (2.99 - 3.29), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.53 se; based on food items.

Generation time: 4.4 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Widerstandsfähigkeit (Ref. 120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (tm=5; K=0.25).

Fishing Vulnerability (Ref. 59153): Low vulnerability (11 of 100).

Comephorus baikalensis (Pallas, 1776)
