What is the southern limit of the native range of Ictalurus catus along the Atlantic slope?

Answer

Florida

The native distribution of the white catfish is delineated across several major drainage systems. Specifically focusing on the Atlantic slope, their range extends from Massachusetts in the north down towards Florida in the south. While they also extend westward into the Gulf coast drainages, the most southern point mentioned along the Atlantic side of their origin is Florida. This contrasts with introduced populations found far west, such as in California, or those inhabiting the Gulf coast drains of states like Alabama and Mississippi, which are part of their historic area but not the extreme southern limit along the Atlantic slope itself.
