western and eastern mosquitofish Region Map

Notes:

Widespread stocking, hybridization, and mis-identification make it difficult to determine the distribution of mosquitofish in the state. We consider G. affinis to be native to the Coosa and Tennessee drainages. G. holbrooki is native to Coastal Plain portions of all Atlantic and Gulf coast drainages. Populations in the Upper Chattahoochee and Upper Savannah warrant further study.


Basin Distribution in Georgia:

Occurs in the Tennessee, Coosa, Tallapoosa, Chattahoochee, Flint, Ochlockonee, Suwannee, St. Marys, Satilla, Ocmulgee, Oconee, Altamaha, Ogeechee, and Savannah River basins.
