Pontic shad
The Pontic shad (''Alosa immaculata'', previously ''Alosa pontica''), also referred to as the Black sea shad or Kerch shad, is a species of clupeid fish in the genus ''Alosa'', native to the Black Sea and Sea of Azov basins.〔( A. pontica (Eichwald,1838) - черноморско-азовская проходная сельдь ) Позвоночные животные России. sevin.ru 〕 ==Distribution== ''Alosa immaculata'' lives in the Black Sea and Sea of Azov, and adults migrate up rivers to spawn.〔 It may also be found in the Marmara Sea in Turkey.〔 It currently migrates up and spawns in six rivers: the Danube, Dnieper, Dniester, Southern Bug, Don and Kuban Rivers. Previously the migrations reached far upstream, up to 1,600 in Danube and 900 km in Don, now dams are restricting the migrations. There is also a landlocked population in Don.〔
