''Alosa caspia'' is a species of clupeid fish, one of the species of shad (genus ''Alosa'') endemic to the Caspian Sea basin.〔Freyhof, J. & Kottelat, M. 2008. (''Alosa caspia''. ) The IUCN Red List of Threatened Species. Version 2014.3. Downloaded on 18 April 2015.〕 FishBase treats separately three subspecies from the Caspian: * Caspian shad, ''Alosa caspia caspia'' (Eichwald, 1838) * Enzeli shad, ''Alosa caspia knipowitschi'' (Iljin, 1927) * Astrabad shad, ''Alosa caspia persica'' (Iljin, 1927) Previously the taxonomic circumscription and geographic range of ''A. caspia'' have been broader, encompassing also the Sea of Azov and Black Sea basins.〔〔Peter J.P. Whitehead (1985) (Subfamily Alosinae ) In: Clupeoid Fishes of the World - an annotated and illustrated cataloge of the herrings, sardines, pilchards, sprats, shads, anchovies and wolf-herrings.

Rome: UNDP FAO.〕〔( A. caspia (Eichwald,1838) - каспийско-черноморский пузанок ) Позвоночные животные России. sevin.ru〕 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''.〔 ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Alosa caspia」の詳細全文を読む スポンサード リンク
