Minnesota water lovers of all sorts like the white sucker. Sport fish, such as walleye, northern pike, and largemouth bass, depend on them as an important source of food. Bait dealers raise them for sale as “sucker minnows,“ though they are not minnows. Anglers find a scrappy fighter has taken their worm, while fishing for perch or smallmouth bass.
The most common fish in Minnesota, white suckers tolerate a wide range of water conditions, from pristine to polluted and temperatures both cold and warm. They feed on insects and other bottom-dwelling crustaceans with a flexible, downward-pointing mouth that has no teeth.
White suckers typically weigh 1-2 pounds and run 12- 20 inches in length. Their soft fins are clear or whitish.
- A white sucker’s fleshy lips are covered with taste buds.
- About 70 species of suckers live in North America.
- Commercially, suckers are often marketed under the name "freshwater mullet."
