- Аннотация: A comparative analysis of data on the morphological, genetic and ecological features ofRussian, Persian and Colchic sturgeons was carried out in order to assess their taxonomicrelations, diagnostic characteristics and distribution patterns in the Ponto–Caspian basin. The results confirm the presence of two close related and morphologically similar species in theCaspian basin − Acipenser gueldenstaedtii and A. persicus, the reproductive isolation of whichwas proved by genetic data. The complex of diagnostic characters of these species includes, in addition to the traditionally accepted body color and the shape of the snout, severalcraniological indices: Pds/Ri and W/Ri. The Colchic sturgeon remains virtually unstudied froma genetic point of view. The results obtained allow us to consider it an independent subspecies− A. persicus colchicus. It differs from the Caspian Persian sturgeon, as well as from theRussian sturgeon with a longer snout and larger values of the craniological index B/Ri. Thedistribution of the Colchic sturgeon in the Black Sea basin requires further research
