Smallmouth Buffalo

Smallmouth Buffalo are large, robust freshwater fish belonging to the Catostomidae (sucker) family, not the carp family as commonly misidentified.

In North Carolina, they are not native but were likely stocked in the early 1900s and are now established in multiple river systems.

Scientific Name: Ictiobus bubalus

Physical Characteristics:
  • They have deep, laterally compressed bodies with bronze to grayish-brown coloration and can reach impressive sizes - typically 40-60 cm but some specimens reach over 100 cm and 30+ kg.

What to know

Key Locations

  • Lake Wylie (holding the state record), the Catawba River system, Pee Dee River drainages including the Uwharrie and Little Rivers, and the French Broad River system.
  • The NC Wildlife Resources Commission has documented their presence in 9 hydrologic units including the Lower Pee Dee, Nolichucky, Rocky, Upper Catawba, Upper French Broad, Upper Neuse, Upper Pee Dee, and Upper Yadkin watersheds.
