Smallmouth Buffalo

The Smallmouth Buffalo is a native North American fish found in Ohio waters, particularly in Lake Erie and the Ohio River drainage systems.

These hardy, stocky fish are members of the sucker family (Catostomidae) and can live exceptionally long lives - recent research has revealed they can live over 100 years, with specimens in Ohio waters commonly reaching 20+ years of age.

Scientific Name: Ictiobus bubalus

Physical Characteristics:
  • Adults typically range from 16-24 inches in length but can grow much larger.
  • They have a distinctive deep, compressed body with a bronze or slate olive back, bronze sides, and a small ventral mouth positioned below the eyes - distinguishing them from bigmouth buffalo.
  • Ohio's state record being a massive 46 pound fish caught at Hoover Reservoir.
