Lacustrine, at depths greater than 30 m, in Lake Ladoga commonly at 50-150 m (Ref. 59043). Specimens measuring 36-40 cm are more than 5 years old. Mature individuals spawn for the first time at 4-6 years (Ref. 59043) from the end of November to December (Ref. 593). Oviparous (Ref. 205). Eggs are buried in unguarded nests (Ref. 205). Adults feed on benthic invertebrates, especially gammarids, molluscs and insect larvae (Ref. 59043). Kottelat, M. 1997 European freshwater fishes.
