- Eurasia: endemic to the Caspian Sea drainage. Construction projects along the rivers entering the Caspian Sea have had a very negative impact. Very rare now in the Volga river (Ref. 12275 ). Migrates to uppermost tributaries of Volga (Ref. 59043 ). Reported to migrate for spawning to the Sura River and its tributaries (the Penza, Aiva, and Inza rivers) as far as Penza Ciry in the 1920s (Ref. 58030 ).
