Open waters of large lakes and medium to large rivers. Forages close to surface. In winter forms large aggregations in backwaters and other still waters. Spawns in shallow riffles or along stony shores of lakes, occasionally above submerged vegetation.

Gregarious. Spawns for the first time at 2-3 years. Usually spawns only one or two seasons. Spawns in May-August at temperatures above 15°C, 2-4 times at 1-2 week intervals, in early morning. Larvae inhabit littoral zone of rivers and lakes, juveniles leave shores and occupy a pelagic habitat, feeding on plankton, drifting insects or invertebrates fallen on the water surface.
