Characteristic feeding method / Life stage (?) |
References (not structured): Kottelat M, Gesner J, Freyhof J (2010) Acipenser gueldenstaedtii. In: IUCN 2011. IUCN Red List of Threatened Species. Comments: Feeds on a wide variety of benthic molluscs, crustaceans and small fish. Feeds on a wide variety of benthic molluscs, crustaceans and small fish. In the sea, the Russian sturgeon inhabits shallow waters of the continental shelf; in the rivers it remains at depths from 2 to 30 m. The larvae are found at considerable depths and in rapid currents. Besides the main diadromus form, a freshwater form that does not migrate downstream to the sea has been reported from various rivers. The Russian sturgeon is a bottom-dwelling mollusc-feeder. They also readily consume crustaceans (shrimps and crabs) fishes and polychaetes. The main food items of juveniles are crustaceans, including mysids and corophiids, and polychaetes (Berg 1948). According to the diet studies in its native region, mussels appeared to be the most important food for the Russian sturgeon (Zolotarev et al. 1996). |
Mobility / Life stage (?) |
References (not structured): Kottelat M, Gesner J, Freyhof J (2010) Acipenser gueldenstaedtii. In: IUCN 2011. IUCN Red List of Threatened Species. Comments: Larvae drift on currents; juveniles then move towards shallower habitats, before migrating to the sea during their first summer. They remain at sea until maturity. |

Known economic impact? | Known References: Degani, G. 2022. Sturgeon (Acipenser gueldenstaedtii) Acclimatization to Optimal Growth Conditions—A Case Study of Adaptation, Nutrition, Reproduction, and Sex Determination. Open Journal of Animal Sciences, 12, pp. 629-661. Comments: The caviar produced from A. gueldenstaedtii is among the most expensive types due to its quality and scarcity. The caviar industry supports a significant number of jobs in regions where sturgeon farming or fishing occurs. |
