Recorded from coastal waters at sea. 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).
