Natural populations across the main Siberian River basins have declined so severely that the species is now classified as Critically Endangered on the IUCN Red List. This narrative analysis synthesizes current scientific knowledge regarding the ecology, reproductive biology, conservation status, and nutritional value of products derived from A. baerii, with the aim of providing an integrated perspective on this species, which has recently been introduced into Romanian aquaculture and occupies the interface between biodiversity and human consumption needs. The species\u2019 remarkable ecological and morphological plasticity, which underlies its wide natural distribution in the Ob, Irtysh, Yenisei, and Lena River basins, has also made it the dominant species in global sturgeon aquaculture, commercially farmed in Europe, Asia, and South America. Reproductive management in farming systems relies on hormonal induction, non-invasive maturity assessment, and controlled hatchery practices, while emerging no-kill technologies enable repeated caviar harvesting without sacrificing the female, improving both ethical standards and economic efficiency. From a nutritional standpoint, A. baerii yields two high-value products: caviar, a rich source of the long-chain polyunsaturated fatty acids EPA and DHA, whose dietary intake has been associated with cardiovascular and neurodevelopmental benefits in the broader nutrition literature, and meat, characterized by high-biological-value protein, a favorable amino acid profile, and significant omega-3 content. By-products such as skin, swim bladders, glands, and cartilage contribute to the higher-value utilization of the species within the circular bioeconomy. Still, notable gaps remain in genetics and sex determination methods, in early life behavioral ecology, and in cryopreservation protocols. Future work should also look at more sustainable feed formulations and new value-added products.<\/jats:p>","DOI":"10.3390\/life16091437","type":"journal-article","created":{"date-parts":[[2026,8,28]],"date-time":"2026-08-28T18:33:52Z","timestamp":1787942032000},"page":"1437","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Siberian Sturgeon (Acipenser baerii, Brandt, 1869) the Relationship Between Genetic Resources and Acclimatization: Ecology, Conservation, and the Nutritional Significance of Meat and Caviar"],"prefix":"10.3390","volume":"16","author":[{"given":"C\u0103t\u0103lina Teodora","family":"C\u00eermaciu (Florea)","sequence":"first","affiliation":[{"name":"Department of Animal Resources and Technologies, Faculty of Food and Animal Sciences, \u201cIon Ionescu de la Brad\u201d University of Life Sciences, 8 Mihail Sadoveanu Alley, 700489 Iasi, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6340-9415","authenticated-orcid":false,"given":"C\u0103t\u0103lin Emilian","family":"Nistor","sequence":"additional","affiliation":[{"name":"Department of Animal Resources and Technologies, Faculty of Food and Animal Sciences, \u201cIon Ionescu de la Brad\u201d University of Life Sciences, 8 Mihail Sadoveanu Alley, 700489 Iasi, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gabriel-Vasile","family":"Hoha","sequence":"additional","affiliation":[{"name":"Department of Animal Resources and Technologies, Faculty of Food and Animal Sciences, \u201cIon Ionescu de la Brad\u201d University of Life Sciences, 8 Mihail Sadoveanu Alley, 700489 Iasi, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Benone","family":"P\u0103s\u0103rin","sequence":"additional","affiliation":[{"name":"Department of Animal Resources and Technologies, Faculty of Food and Animal Sciences, \u201cIon Ionescu de la Brad\u201d University of Life Sciences, 8 Mihail Sadoveanu Alley, 700489 Iasi, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"773","DOI":"10.1046\/j.1523-1739.1993.740773.x","article-title":"Sturgeons and paddlefishes: Threatened fishes in need of conservation","volume":"7","author":"Birstein","year":"1993","journal-title":"Conserv.
