Distribution Black Sea shad is widely distributed in the western part of the Black
Sea, inhabiting the Romanian, Bulgarian, Russian, Ukrainian and Anatolyan coasts.
In the Danube, it is encountered up to Iron Gates II; in the Dnieper, up to the Rapids,
and at the Dniester’s outfalls. It also occurs in the Sea of Azov and the Caspian Sea,
often migrating in the Danube, Dniester and Dnieper (Navodaru and Maximov
2014).
Sizes Maximum 23 cm; common 9 cm–18 cm.
Biology and Ecology A euryhaline species, Black Sea shad winters in the Sea. It
occurs in spring in the coastal area, in mixed shoals with the other related species, at
a water temperature of 6
C. Some of the individuals go up the Danube, the other
remain at the outfalls. Spawning takes place in late April – early June. The retreat of
fingerlings and adults into the sea occurs during August–September (Zaharia
et al. 2013).
Fishery Black Sea shad is fished using pound nets, shad gillnets, beach seines and
mid-water trawl (Radu et al. 2011).
