Stocked in almost all water bodies as lakes, rivers and streams, usually not stocked in water reaching summer temperatures above 25°C or ponds with very low oxygen concentrations. Feeds on a variety of aquatic and terrestrial invertebrates and small fishes. At the sea, preys on fish and cephalopods. Undertakes short spawning migrations. Anadromous and lake forms may migrate long distances to spawning streams (Ref. 59043).
