Etymology: Pseudoscaphirhynchus: Greek, pseudes = false + Greek, skaphe = boat + Greek, rhyngchos = snout (Ref. 45335).

Issue
Species of the genus Pseudoscaphirhynchus belong to the subfamily Acipenserinae, and not Scaphirhynchinae as it was previously considered (V. Birstein, pers. comm. 03/05 ).

; zoet water; brak water demersaal; potamodroom (Ref. 51243); diepte 1 - 2 m (Ref. 109751). Temperate; 10°C - 20°C (Ref. 2059)

Asia: Former USSR: Amu Darya River from the Pyandzh to the mouths and lower tributaries. Sometimes in the brackish water of Taldyk Bay, the delta of the Amu Darya in the Aral Sea. Considered close to extinction (Ref. 6866). Registered in the 1984 USSR Red Book; 1985 Turkmen SSR Red Data Book; 1996 IUCN Red List (Ref. 35930).

Lengte bij maturiteit / Grootte / Gewicht / Leeftijd

Maturity: L_m 45.0 range ? - ? cm
Max length : 75.0 cm TL mannelijk / geslacht onbekend; (Ref. 593); max. gepubliceerd gewicht: 2.0 kg (Ref. 593)

Its natural habitat and population have declined due to the breakage of the hydrological regime of the Amu Dariya River. Usual weight not more than 600-700 grams. Females with mature hard roe, very rare. Apparently sensitive to oxygen content in the water, changes in its chemical content, and to pollution. Fishing is prohibited (Ref. 35930). Spawns at 16° C (Ref. 719).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00331 (0.00148 - 0.00739), b=3.16 (2.98 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.4 ±0.3 se; based on diet studies.

Generation time: 8.5 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Weerstandsvermogen (Ref. 120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (K=0.16; tm=6-7).

Fishing Vulnerability (Ref. 59153): High vulnerability (59 of 100).

Prijsklasse (Ref. 80766): Unknown.
