Abstract

Here we present evidence of the first field observation of the nonnative Ictalurus furcatus (Blue Catfish) occurring on the Satilla River, GA, in May 2011, and additional collections since then. This is the second large, non-native riverine catfish to be found in the Satilla River basin. Pylodictis olivaris (Flathead catfish) was first collected from the Satilla River in May 1996. The ecological effects of Blue Catfish on native mussel and fish species in the Satilla River are currently unknown, but competition with native catfishes is likely.
