Sometimes, ANS may be native to specific waterways in Georgia but not native to ALL waterways, like the Flathead Catfish. Native to Gulf drainages, including the Coosa River watershed in northwest GA, flatheads have been introduced into other waters of Georgia. This apex predator can exceed 100 lb, attaining such sizes by preying on a plethora of native fish species. In the Satilla River, GADNR staff are removing non-native flathead and blue catfish to reverse their detrimental effects on prized redbreast sunfish and other native fish species.​
