La pisciculture de la maison tropicale fait figure de première expérience dans l'élevage durable d'esturgeons de Sibérie. Le corps allongé et fuselé comporte cinq rangées longitudinales de grosses plaques osseuses.

Il trouve sa nourriture, principalement des larves d'insectes, des vers et des petits crustacés, à l'aide de ses barbillons pour les mettre dans sa bouche allongée en forme de bec. These factors have led researchers in the past to identify over 40 additional species that were rejected by later scientists.The family contains 8 extinct species and 28 extant species/subspecies (include 1 species of Globally, sturgeon fisheries are of great value, primarily as a source for During the 19th century, the US was the global leader in caviar production, having cornered 90% of the world's caviar trade.By the turn of the century, commercial production of sturgeon caviar in the US and Canada had come to an end. Their average lifespan is 50 to 60 years, and their first Throughout this extensive range, almost all species are highly threatened or vulnerable to extinction due to a combination of No species is known to naturally occur south of the equator, though attempts at sturgeon The sturgeons' electroreceptors are located on the head and are sensitive to weak electric fields generated by other animals or geoelectric sources.The wide range of the acipenserids and their endangered status have made collection of systematic materials difficult.
Dans le Baïkal il y a près de 50 variétés de poissons, 17 sont bons pour la pêche : le lavaret, l’ombre, le brachymystax lénok, le taïmen (hucho taimen), l’esturgeon, la lotte, la perche, le brochet, le gardon, la vandoise (leuciscus leuciscus), le carassin, la brème... et le fameux omoul (coregonus migratorius) de la famille des salmonidés, poisson endémique du Lac. Il est parfois surnommé la « Perle de Sibérie ». I never caught a single Sturgeon and I'm at level 10.

Regulatory protections and conservation efforts were put in place by state and federal resource agencies in the US and Canada, such as the 1998 US federal moratorium that closed all commercial fishing for Atlantic sturgeon.Beginning with the 1979 US embargo on Iran, poaching and smuggling sturgeon caviar was big business but an illegal and dangerous one.In response to concerns over the future of sturgeons and associated commercial products, international trade for all species of sturgeons has been regulated under Sturgeons are long-lived, late maturing fishes with reproductive cycles that include long migrations, and require specific environmental conditions.In addition to global restocking efforts, the monitoring of populations and habitat, and various other conservation efforts by national and state resource agencies as applicable to their respective countries, several conservation organizations have been formed to assist in the preservation of sturgeons around the world.
Les blocs de glace atteignent une hauteur de 3 mètres, et certains culminent même à plus de 5 mètres. Elle a été introduite en France dans plusieurs piscicultures à la fin des années 80 à des fins scientifiques.Cette espèce est menacée sur la liste rouge mondiale de l'IUCN.
