Abstract:

A survey was conducted to determine the fish fauna and its distribution in the central Chattahoochee River drainage. This is a zoogeographically important, but sparsely collected area. Fishes from the following 19 families were recorded from the study area: Petromyzonidae, Lepisosteidae, Amiidae, Anguillidae, Clupeidae, Esocidae, Cyprinidae, Catostomidae, Ictaluridae, Aphredoderidae, Belonidae, Cyprinodontidae, Poeciliidae, Atherinidae, Cottidae, Serranidae, Centrarchidae, Percidae, and Soleidae. The distributions of the 83 species of fishes currently occurring in the area were recorded and plotted. These distributions were based on specimens housed in various ichthyological collections (Cornell University, Florida State University, Tulane University, University of Alabama, University of Michigan) and personal collections, which are housed in the Auburn University collection. The fish fauna was found to be sparse compared to adjacent systems. This is possibly due to Pleistocene flooding, homogeneity of habitat, infertility of the area, and physiographic isolation. The Fall Line was found to be less important as a barrier to fish movements in the Chattahoochee River than in adjacent systems. This can be explained by Pleistocene flooding and physiography of the drainage. Several range extensions and one previously unreported introduction were recorded.
