Trout Stocking Many anglers assume all trout in southeastern Minnesota are stocked.
This is not the case, as many trout populations are sustained by natural reproduction. To provide a trout fishery in streams where trout have good adult cover but poor reproductive success. To reintroduce trout into streams that may once again have sustainable habitat. Stocking trout fingerlings. State-owned fish hatcheries in Altura, Lanesboro and Peterson supply most of the trout stocked in southeastern Minnesota.
