White sucker

The White sucker, Catostomus commersonii, is a bottom-feeding freshwater fish inhabiting North America from Labrador in the north to Georgia and New Mexico in the south. It is a long, round-bodied fish with a dark green, grey, copper, brown, or black back and sides and a light underbelly. When full grown, it is between 12 and 20 in long and weighs between 2 and 4 lb. It will eat almost anything it can, but most commonly small invertebrates and plant matter. Larger predatory fish species such as walleye, trout, bass, northern pike, muskellunge, and sauger prey on the white sucker.

A very common fish, the white sucker is usually not fished for food, though it is considered good to eat. It is most often used as bait; the young are sold as sucker minnows. When it is eaten by humans, it is usually processed and sold under the name of mullet. Other common names for the white sucker include bay fish, brook sucker, common sucker, and mullet. The white sucker is often confused with the Longnose sucker, Catostomus catostomus, since they look very similar.
