The essential part of his life is spend in the estuarine zone, with just short incursions in the littoral zone (Ref. 51442). The migratory form is grouping together in the estuarine zone for reproduction (Ref. 51442). Prefers cold and deep lakes and also moving waters (Ref. 682). Sedentary resident stocks exists in some lakes; those found in coastal and estuarine areas are migratory stocks (Ref. 682).
