Where To Find

Abundant and widely distributed in Ozarks. Range extends northeastward from the Ozarks into prairie tributaries of the upper Mississippi River. Also found in Moniteau Creek (Moniteau County) and Cedar Creek (Boone and Callaway counties).

The northern hog sucker is one of the most abundant and widely distributed stream fishes in the Ozarks. It inhabits permanent streams with moderate to swift current, clear water, and a gravel or rubble bottom. It is usually found in riffles but also occurs in pools with current. This species’ coloration makes it almost invisible when in rests on a gravel stream bed.

An energetic feeder, overturning rocks and stirring up the bottom as it forages for immature aquatic insects and other bottom life with its fleshy, sucking lips.

A nongame fish.

Life Cycle

Individuals can live for 11 years. Northern hog suckers spawn in April or early May, near the heads of gravelly riffles.

This fish is seldom taken on a baited hook but may be caught by gigging, snagging, and snaring. It's a less desirable food fish than other suckers, since much of its bulk is made up of the bony head, so there is less usable meat.

Other fishes, especially the smallmouth bass, longear sunfish, and various minnows, commonly follow foraging hog suckers to feed on the small organisms exposed by the hog suckers' energetic rooting.

About Fishes in Missouri
Missouri has more than 200 kinds of fish, more than are found in most neighboring states. Fishes live in water, breathe with gills, and have fins instead of legs. Most are covered with scales. Most fish in Missouri “look” like fish and could never be confused with anything else. True, lampreys and eels have snakelike bodies — but they also have fins and smooth, slimy skin, which snakes do not.
