Smallmouth Buffalo

Smallmouth Buffalo

The Smallmouth Buffalo is a native Missouri fish species in the Catostomidae (sucker) family, not the carp family despite common misconceptions.

Recent research has revealed Smallmouth Buffalo are exceptionally long-lived, with some specimens exceeding 90-100 years of age.

Scientific Name: Ictiobus bubalus

Physical Characteristics:
  • These stocky fish have a characteristic hump behind their heads, with coloration ranging from olive-bronze to bluish-gray dorsally, fading to pale yellow or white bellies.
  • They have small, downward-facing sucker mouths and can reach substantial sizes - Missouri's Lake of the Ozarks produced a former state record of 36 pounds, 12 ounces.

What to know

Habitat Distribution

  • Found throughout Missouri's major river systems and in large reservoirs.
  • They prefer clear to moderately turbid waters with moderate to fast current, dense aquatic vegetation, and silty bottoms.

Key Locations

  • Missouri River, Mississippi River, Osage River, Lake of the Ozarks, Table Rock Lake, and Truman Lake.

Specific Spots

  • Target areas with structure like boulder fields, sunken trees, deeper pools below rapids, eddies, and areas where streams enter lakes.
  • In reservoirs, focus on deeper areas near dam structures and around submerged timber.
  • In rivers like the Missouri and Mississippi, concentrate efforts around wing dams, riprap, and scour holes.
  • For Missouri's large reservoirs, fish the deeper, clearer waters on points and drop-offs.
