Lacustrine. Males reproduce initially at 3-4 years, females at 5. Spawns on gravel near shore or, depending on population, in depths up to 50 m. Spawning time depends on depth and apparently on temperature at that location, from November to December in shallow water to February in deepest places (Ref. 59043).
