Etymology: Acipenser: Latin, acipenser = sturgeon, 1853 (Ref. 45335).
Eponymy: Peter Leopold Ivanovich von Schrenck (aka Schenk or Shrenk) (1826–1894) was a Russo-German zoologist, geographer and ethnographer who was Director (1879) of the Imperial Academy of Sciences, St Petersburg. [...] (Ref. 128868), visit book page.

Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; freshwater; brackish; demersal; anadromous (Ref. 26364). Temperate; 10°C - 20°C (Ref. 2059)

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

Asia: Endemic to the Amur River system. Two morphs, brown and gray, represent the species in the Amur River basin. Occurrence in the Sea of Japan (Ref. 11102) needs confirmation.

Length at first maturity / Size / Weight / Age

Maturity: Lm 108.8, range 96 - 125 cm
Max length : 300 cm TL male/unsexed; (Ref. 40142); max. published weight: 190.0 kg (Ref. 40142); max. reported age: 65 years (Ref. 56448)

Short description Identification keys | Morphology | Morphometrics

Biology     Glossary (e.g. epibenthic)

Adults occur in stretches of rivers with sandy or stony bottom. Feed on benthic organisms. Highly prized fish (Ref. 41072).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

The gray morph females in the Amur River reproduce at least every four years (Ref. 40142).

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=0.00257 (0.00160 - 0.00413), b=3.24 (3.11 - 3.37), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.1 se; based on diet studies.
Generation time: 22.0 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179):  Very Low, minimum population doubling time more than 14 years (tm=8-14; tmax=65; Fec=29,000).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (87 of 100).
Price category (Ref. 80766):   Unknown.
Nutrients (Ref. 124155):  Calcium = 13.5 [7.7, 23.3] mg/100g; Iron = 0.245 [0.148, 0.387] mg/100g; Protein = 17.5 [15.0, 20.2] %; Omega3 = 0.329 [0.180, 0.595] g/100g; Selenium = 23.9 [12.6, 47.1] μg/100g; VitaminA = 4.56 [1.63, 12.77] μg/100g; Zinc = 0.469 [0.334, 0.657] mg/100g (wet weight);
