“…Thus, it seems very likely that the European eels were not released from culture ponds into nearby natural waters. Instead, A. anguilla may have been accidentally mixed with A. japonica fry imported from other regions, as the latter species is stocked annually to support the local economy (Byeon 2015). Future studies interested in the exact timing of entry could attempt to estimate the import year through otolith analysis, provided A. anguilla specimens are large enough.…”

We surveyed the proportion of anguillid eel species inhabiting South Korea natural waters. From September 2014 to August 2015, 429 eels were collected in various habitats for identification using morphological features and DNA-based molecular methods. We found 424 Japanese eels (Anguilla japonica, 98.8%), two European eels (A. anguilla, 0.5%), one American eel (A. rostrata, 0.23%), one tropical eel (A. marmorata, 0.23%), and one short-finned eel (A. bicolor pacifica, 0.23%). Three (A. anguilla, A. rostrata, and A. bicolor pacifica) are exotic species to the natural waters of South Korea; this study is the first record of their distribution in this region. Specifically, A. anguilla was found in the Lake Soyang and Cheongpyeong, while A. rostrata was found only in the Lake Cheongpyeong, and A. bicolor pacifica was found in the Geum River estuary.
