  • Distinguished by their bluish-silver coloration with white bellies, deeply forked tail, straight anal fin (versus rounded in channel catfish), and absence of dark spots.
  • In Mississippi waters, they can reach weights of 5-20 pounds commonly, with trophy fish exceeding 130 pounds and lengths over 5 feet.

What to know

Habitat Distribution

  • Native to the Mississippi River Basin and thrive throughout Mississippi's river systems, oxbow lakes, reservoirs, and brackish coastal waters.
