Lacustrine and marine in open water. At sea, forages close to coast (Ref. 59043). Adults form pelagic schools in deeper lakes (Ref. 4779). Spawning occurs along shores, at 3-10 m depth, rarely to 22 m depth or just below surface, in deeper in clear lakes and closer to surface in lakes with humic waters (Ref. 59043), on shallow sand or gravel substrate. Anadromous in the Baltic. Adults feed on planktonic crustaceans (Ref. 4779).
Ascend a short distance up the rivers in shoals in late August to mid-October. Mature in the second year (lacustrine forms later) and the young ones descend in late summer (Ref. 4779).
