Detail
Danube drainage (absent from Danube main river except upper course and stretches with fast current). Native: Albania; Austria; Bosnia and Herzegovina; Bulgaria; Croatia; Czech Republic; Hungary; Macedonia, the former Yugoslav Republic of; Montenegro; Poland; Romania; Serbia (Serbia); Slovakia; Slovenia; Ukraine. Still frequent in suitable habitats in the Danube drainage. Though the population has declined, it is extirpated from the upper Danube (1830s). Habitat: Riffles of small, fast-flowing rivers and bottom of large rivers with water velocities of 0.7 m/s and more, stone bottom, in submontane zone. Young individuals prefer slow currents and shallow shoreline habitats with sand bottom. Spawns in shallow habitats with very high current (about 1 m/s). Biology: In laboratory, spawns several times between late May and mid-September, at temperatures above 11°C. Males wait for females at spawning sites. To spawn, both sexes move to surface or open water. Eggs drift with current, sink to bottom and then stick to substrate. Adults are nocturnal and solitary, juveniles are active at day. No data on food in the wild.
