Black Bullhead

Black Bullhead in Colorado are non-native catfish that have established populations in several river basins.

First observed in Colorado in 1969, with the most recent documented observation in 2015, these fish are considered an invasive species and are not actively stocked by Colorado Parks and Wildlife.

Scientific Name: Ameiurus melas

Physical Characteristics:
  • Black Bullheads can be distinguished from other bullheads by their dark-colored chin barbels, slightly notched tail fin, and uniform dark coloration without mottling.
  • They typically reach 8-10 inches but can grow up to 24 inches.

What to know
