Where To Find

In natural waters, this species is confined to the southern half of Missouri, but it has been widely stocked in small reservoirs and ponds.

This sunfish prefers warm, clear waters with no noticeable current and an abundance of aquatic plants. In streams, it prefers protected bays and overflow pools and avoids the main channel. Most active in daylight.

Carnivorous, feeding primarily on snails and other mollusks. This diet is what inspired the alternate common name "shellcracker." The throat teeth of this fish have broad, flattened surfaces, which are well suited for crushing mollusk shells.

Life Cycle

Individuals can live for 6 years. In our state, nesting is in May or June, and sometimes again in August. Nests are saucer-shaped depressions that are fanned out in silt if no gravel is present. This species nests in colonies, with the rims of the nests often almost touching.

An excellent panfish, the redear sunfish contributes significantly to the creel in impounded waters where it has been introduced. Most are caught from spawning "beds" in early summer. Can be taken on artificial lures, but natural baits, such as earthworms and grubs, are most effective.

Stocked in many small ponds and fish hatcheries to control the spread of certain aquatic parasites. Redear prey upon aquatic snails, which are an important link in the lifecycles of certain aquatic parasites.

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.
