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

Northwest Pacific: Bering Sea, Tumnin (Datta) river, to northern Japan and Korea. This species was formerly regarded to be a population of Acipenser medirostris (Ref. 6866). International trade restricted (CITES II, since 1.4.98; CMS Appendix II).

Biology     Glossary (e.g. epibenthic)

Commercially cultured in Japan (Ref. 6866). From April to May adults feed in fresh water and return to the ocean during the fall (Ref. 12218).

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

Eggs are laid from April to August under the substrate in sandy areas (Ref. 12218).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00282 (0.00125 - 0.00635), b=3.21 (3.03 - 3.39), based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±0.3 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Very high vulnerability (84 of 100) .
unknown
Price category (Ref. 80766):   Unknown.
