Thirteen species are exotic at the country (Butis koilomatodon, Coptodon rendalli, and Oreochromis niloticus) or the basin level (e.g., Pygocentrus nattereri and Salminus brasiliensis). Threatened (Paragenidens grandoculis, Genidens barbus, and Lutjanus cyanopterus) and near threatened (Cynoscion acoupa, Dormitator maculatus, Lutjanus jocu, Lutjanus synagris, and Mugil liza) species are peripheral. Most species are native (87.8%), euryhaline/peripheral (80%) and zoobenthivorous (33.9%). Carangiformes, Siluriformes and Eupercaria incertae sedis were the most representative orders for the 115 species recorded. Here, we present the first comprehensive fish biodiversity assessment of the Doce River estuary and a summary of the main impacts and their drivers for the whole river since the early 18th century. The Doce River has undergone severe changes over the last centuries (e.g., flow regulation, pollution, habitat and species loss).
