Short description

Dorsal spines (total): 0; Dorsal soft rays (total): 11-13; Anal spines: 0; Anal soft rays: 13 - 17

Lacustrine and marine in open water. At sea, forages close to coast (Ref. 59043). Forms pelagic schools in deeper lakes (Ref. 4779). Spawns along shores, at 3-10 m depth, rarely to 22 m depth or just below surface. Spawns deeper in clear lakes and closer to surface in lakes with humic waters (Ref. 59043). Spawns on shallow sand or gravel substrate. Anadromous in the Baltic. Feeds on planktonic crustaceans (Ref. 4779).

IUCN Red List Status (Ref. 115185)
