|Habitat and Ecology:||
A wide variety of shallow, warm lowland lakes and slow-flowing lower reaches of large rivers and canals. Often very abundant on bottom of large sandy rivers. Spawns along shores on submerged vegetation, roots or even on shallow gravel bottom.
Predominantly nocturnal. Gregarious. Lives more than 10 years. Males reproduce for the first time at two years, females at three. Most individuals spawn 2-3 times per season, at intervals of about 10 days and spawn in more than one year. Spawns in May-July at temperatures above 15°C, in early morning. Eggs are sticky and larvae inhabit still water bodies. Feeds on benthic invertebrates. Often hybridizes with Vimba vimba. Most reported hybrids with Abramis brama in fact are A. brama with pharyngeal teeth 2,5-5,2 (vs. usually 5-5).
