Satilla River Flathead Catfish Project

Additional Information

Blue Catfish Removal

While the FRP was created with the intended purpose of removing flatheads from the Satilla, a second non-native species has been discovered in the river during removal efforts. In May 2011, GA DNR staff captured a single blue catfish (Ictalurus furcatus) while conducting flathead removals in the Satilla (Bonvechio et al. 2012). Though it is believed that flathead introduction into the Satilla occurred due to illegal stocking by anglers in the mid 1990’s, blue catfish introduction into the river likely occurred when fish migrated to the Satilla River via the intercoastal waterway during high water periods. 

A total of seven blue catfish were recovered from the Satilla River in 2011 and two individuals showed up in an access creel survey in 2014. In 2016, a notable spike in blue catfish recruitment was observed with several dozen juvenile individuals being captured, including a gravid adult. Nonetheless, as a large catfish that can exceed 100 lb as an adult, the potential exist for this non-native fish, like the flathead, to have negative implications on native species. As a result, GA DNR staff continue to monitor the blue catfish population in the Satilla while removing all specimens observed during sampling efforts.
