生物学特性     字汇 (例如 epibenthic)

Anadromous, semi-anadromous, lacustrine, lacustrine-riverine, and riverine stocks have been reported. Most stocks are migratory, spending most of year at sea, sometimes rather far from coast (Ref. 59043). Stays mainly in the lower reaches of the rivers (Ref. 593) with slow current, large lakes and their tributaries, floodplain lakes, deltas and estuaries, marine waters with salinity up to 6-10%. Enters rivers in July - August and reaches spawning sites by October - November. In larger rivers, moves upriver up tp 2000 km (average speed 20 km/day). Spawns for the first time at 6-14 years, 47-50 cm SL. Spawns in rapids or shallows, at 1-2°C, when rivers start freezing. Adults leave spawning sites in winter (Ref. 59043). Eggs are buried in unguarded nests (Ref. 205). Eggs hatch in 150-180 days; peak hatching usually in April. Juveniles feed on plankton in winter (during which they do not cease active foraging) and benthic invertebrates in summer (Ref. 59043). Status of threat: Important commercial species but rapidly declining (Ref. 59043).

Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00417 (0.00267 - 0.00651), b=3.24 (3.11 - 3.37), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  3.5   ±0.3 se; based on size and trophs of closest relatives
Generation time: 10.0 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
回复力 (Ref. 120179):  低的, 最小族群倍增时间4.5 - 14 年 (tmax=23).
脆弱性 (Ref. 59153):  High vulnerability (63 of 100) .
价格分类 (Ref. 80766):   Very high.
