Etymology: Acipenser: Latin, acipenser = sturgeon, 1853 (Ref. 45335);  transmontanus: The specific name is derived from the Latin acipenser (sturgeon), trans (beyond), and montanus (mountain) (Ref. 27436).  More on author: Richardson.

Korte beschrijving Morfologie | Morfometrie

Dorsale stekels (totaal): 0; Dorsale zachte stralen (totaal): 44-48; Anale zachte stralen: 28 - 31. Distinguished by the 2 rows of 4 to 8 bony plates on a midventral line between the anus and anal fin, and about 45 rays in the dorsal fin (Ref. 27547). Gray or brownish above, paler below; fins gray (Ref. 27547). Barbels situated closer to snout tip than to mouth; no obvious scutes behind dorsal and anal fins (Ref. 86798).

Biologie     Verklarende woordenlijst (b.v. epibenthic)

Spends most of its time in the sea, usually close to shore (Ref. 27547). Enters estuaries of large rivers and moves far inland to spawn (Ref. 5723). Individuals larger than 48.3 cm feed mainly on fishes; smaller ones feed mainly on chironomids, but also takes small crustaceans, other insects and mollusks (Ref. 1998). Feeding ceases just before spawning (Ref. 1998). Excellent food fish that is sold fresh, smoked or frozen (Ref. 9988). Eggs marketed as caviar (Ref. 1998). In the past, the airbladder was made into isinglass (Ref. 27547).

Life cycle and mating behavior Geslachtsrijpheid | Voortplanting | Kuitschieten | Eieren | Fecundity | Larven

Adults return to the sea after spawning (Ref. 27547). Spawning frequency interval every 4 years for younger females and every 10-11 years in older females (Ref. 1998).

Preferred temperature (Ref. 115969): 8.3 - 12.2, mean 9.7 °C (based on 80 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00316 (0.00159 - 0.00628), b=3.18 (3.01 - 3.35), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
