Distribuição Países | Áreas da FAO | Ecossistemas | Ocorrências | Point map | Introduções | Faunafri

Europe and Asia: large rivers draining to Black, Azov, Caspian and Aral Seas. Introduced or native to Northern Dvina drainage (White Sea basin) where it is presently spreading from warmer upper reaches (Vychegda system) northward. Introduced in River Volkhov (a tributary of Lake Ladoga), in Rhine in 1995 and invasive in Vistula drainage, coming from Black Sea basin through Prypet-Bug canal (connecting Dniepr and Vistula drainages).

Descrição suscinta Chaves de identificação | Morfologia | Morfometria

Differs from Ballerus ballerus by having small and inferior mouth, 47-54 scales on lateral line, and large eye, about equal to snout length (Ref. 59043).

Biologia     Glossário (p.ex. epibenthic)

Occurs in fast flowing rivers. Eastern, brackish populations enter the lower reach of rivers for spawning (Ref. 1441). Inhabit large lowland rivers and estuaries. Active at night. Prey on benthic invertebrates. Semi-anadromous populations forage in large brackish-water habitats in estuaries around Black Sea. Spawn in large aggregations in fast-flowing water on gravel bottom or submerged vegetation. Usually rare and threatened due to water pollution (Ref. 59043).

Ciclo de vida ou comportamento de acasalamento Maturities | Reprodução | Spawnings | Egg(s) | Fecundities | Larvas

Spawn in large aggregations in fast flowing water on gravel bottom or submerged vegetation. Semi-anadromous individuals begin spawning migration in November in Kura (Ref. 59043). Sticky eggs attach themselves to stones or plants (Ref. 9953).
