Fishes of Georgia Project
Complete fish books and/or distributional atlases have been published for almost
every state within the southeast. Although Georgia is ranked among the top five U.S. states in richness of freshwater fishes,
this is the first attempt that we are aware of to document distributional data for the freshwater
fish fauna of Georgia. We hope the information provided here will be a resource for government, educational, and
public use and facilitate conservation and research efforts for Georgia fishes.
For this project we attempted to include all fishes that can be encountered within freshwaters of
Georgia. We also included a selection of marine fishes that enter freshwater or are commonly
encountered within the tidal portions of Georgia's coastal rivers and streams. We designate these as
marine species on the species account pages.
Methods
All distributional data provided here were developed using museum records and other documented occurrences (primary
literature, personal field collections, and state/government field collections). These data were compiled into
a database and each collection was georeferenced. Draft distribution maps were then reviewed for accuracy. Questionable
occurrence records were verified or eliminated from the database after examining specimens or photographs
of specimens. Correspondence with original collectors and museum curators was used to verify records on
some occasions.
We chose to use 10-digit HUCs to define the distribution of each species. Providing coarser scale
(HUC 8) data would be less useful and finer scale data (e.g. dots or HUC 12 watersheds) would
compromise the locations of federal and state listed species. Furthermore, dot maps may be misleading
to laypersons who might infer that a species only occurs at the marked locations, when in fact,
they occur within many unsampled locations throughout the watershed. For more information on HUCs
see the Watersheds
of Georgia page. We also chose to only include
known occurrences of a species rather than a full distribution based on known and potential occurrences of each species.
Although this method will likely underestimate a species range, this method does not make any assumptions about
watersheds where a record does not occur. It also helps other ichthyologists identify watersheds where
additional sampling may be needed.
Please be aware that these distributions include all records of a species and may not reflect
their current distribution. Current distributions may be smaller due to historical records being
included or may be larger due to either range expansions or limitations of the data (lack of records).
Currently, the database used to create the distribution maps contains 159,207 unique fish records, within
19,028 collections at 5,930 unique localities. Most of these collections are focused in the northwestern portion of the
state where a higher proportion of the state's threatened and endangered species occurs (map to right shows unique
collection localities with red circles).
Our Thanks
We would like to generously thank all those who have helped with advice on maps, double-checking information, and layout of this
website, including Mary Freeman, Deb Weiler, and the many members of the Freeman Lab.
We would especially like to thank those people that contributed photos for this effort, including Noel Burkhead,
Brady Porter, Chris Skelton, Howard Jelks, David Scott, and Pat O'Neil.
We would also like to thank those people (groups) who submitted
large datasets to help with distribution coverages, including authors of the Fishes of the Middle Savannah River Basin (Barton C. Marcy,
Dean E. Fletcher, F. Douglas Martin, Michael H. Paller, Marcel J. M. Reichert), Tennessee Valley Authority, Georgia DNR Stream Survey
Team (Patti Lanford), Georgia DNR Fisheries - Standard River/Reservoir sampling (Dennis Schmitt), Georgia DNR Natural Heritage Program,
Gerry Dinkins, Florida Museum of Natural History, and William Birkhead.
Many thanks also goes out to those whom have counted scales, counted fin rays, and examined pores, including those at Florida
Museumn of Natural History, Cornell, University of Alabama Ichthyological Collection, and Auburn Museum.
Funding Sources
