Etymology: Acipenser: Latin, acipenser = sturgeon, 1853 (Ref. 45335 ) .

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.

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 38-53; Anal spines : 0; Anal soft rays : 20 - 32. Body shields in 5 rows; dorsal shields 11 to 15, lateral shields 32 to 47 and ventral 7 to 10.

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 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00269 (0.00167 - 0.00434), 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; 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);
