Habitat

White suckers inhabit cool streams, rivers, and lakes throughout the Great Lakes region and northern United States. They are typically found in shallow areas with rocky or sandy bottoms where they feed on algae, small invertebrates, and detritus. Most anglers encounter them incidentally while fishing for other species, though they can be caught on small hooks with worms or other natural baits.
