Biology

provided by Fishbase
Lacustrine, pelagic, usually at 0-40 m during summer. Feeds on plankton and insects; preys on juvenile Perca fluviatilis in summer. Spawns at surface over deep water, off-shore. Spawns for the first time at 2-3 years and in first half of December, when temperature falls below 7?C. Males aggregate at surface and females ready to spawn come from deeper water to join these aggregations. Eggs sink to bottom and hatch in March. Larvae swim to surface and start to feed after 8 days (Ref. 59043). Also Ref. 13813, 47057.
