Detail
Vimba vimba (Linnaeus, 1758): Caspian, Black and Baltic Sea basins (Sweden and Finland north to 62-63°N), North Sea basin from Elbe to Ems drainages. In Finland restricted to coastal waters. In Black Sea basin, absent in Anatolia west of Çoruh drainage (eastern Anatolia). Extirpated in Crimea. Introduced in Rhine. Semi-anadromous populations declined in the Baltic and Black Sea basins. Brackish estuaries, large to medium rivers and some large subalpine lakes. Sedentary populations occur even in small rivers of barbel zone. Spawns on gravel in riffles in shallow, fast-flowing streams and rivers. Lives up to 15 years. Spawns for the first time at 3-5 years. Spawns in May-July (April in Terek and some subalpine lakes) when temperature rises above 15°C. Semi-anadromous populations forage in freshened parts of sea and undertake long distance spawning migrations. Lacustrine populations migrate to fast-flowing tributaries. In Dniepr and Kuban, spawning migration starts in September, decreases in winter and resumes in March-May. Individual females spawn several times during a period of 2-3 weeks. Usually spawns for several years. Spent adults return to foraging habitats. Feeds predominantly on small molluscs and insect larvae.
