Abstract:

A survey of fishes of the Flint River, Georgia, was done to determine both faunal composition and distribution within the drainage. The Flint River, one of two major branches to the Apalachicola River drainage, consists of 8,460 square miles throughout southwestern Georgia. Distribution of fish species was little known in this particular drainage. Altogether, 83 species of fishes are known from the Flint, representing 18 families. Five other species are also considered as probably occurring in the drainage. A total of 77 species were collected during the survey. Distribution and abundance of specimens from 92 collections at 83 localities are mapped and discussed. Remarks on habitat and nuptial pigmentation are included. The number of species in the Flint River was found to be about equal to that of adjacent drainages. Range extensions and reports on eight introduced species are presented. The following species are reported for the first time from the Flint drainage: Dorosoma petenense, Notropis cummingsae, N. euryzonus, N., lutipinnis, N. welaka (also new state record), Pimephales promelas, Carpiodes cyprinus, Moxostoma rupiscartes and Noturus gyrinus. Endemic species to the Apalachicola River drainage include Notropis callitaenia, N. hypsilepis, N. eury-zonus, N. zonistius (introduced elsewhere), Moxostoma sp. cf. M. poecilurum, Moxostoma lachneri and Micropterus sp. cf. M. coosae.Eight species of fishes were found restricted to the Piedmont Province. Nineteen species were found only on the Coastal Plain. One species (Hybopsis harperi) was collected only on the Ocala Limestone portion of the Coastal Plain. Several forms (42.1 per cent of total fauna) were found throughout the Flint drainage. Five species are reported rarely collected from the Flint. Five forms, though not actually collected, are reported as probably occurring in the study area.Notropis emiliae, N. texanus, Aphredoderus sayanus, Centrarchus macropterus and Etheostoma fusiforme are normally coastal plain forms that were found in the headwaters of the Flint River system.
