Alosa caspia is a species of alosid fish, classified as one of the shad species (genus Alosa ) endemic to the Caspian Sea basin. [1]
FishBase treats separately three subspecies from the Caspian: [2]
Previously, the taxonomic circumscription and geographic range of A. caspia were broader, encompassing the Sea of Azov and Black Sea basins. [2] [3] [4] At one point, up to ten subspecies were recognised; these included forms now classified as Alosa tanaica (and its synonyms) and even the Balkan freshwater endemics Alosa macedonica and Alosa vistonica .
