Lake Tempe is located in three regency areas in South Sulawesi, namely Wajo Regency, Sidrap Regency, and Soppeng Regency. Lake Tempe is known to have high productivity, including the productivity of its fish. This study aims to determine the status of the latest fish species at Lake Tempe. Sampling was carried out in 2016 and 2017. Fish were caught using diverse fishing gears, namely gillnet, bottom trap, surface trap, and net. Fish species were identified based on their morphology. Nineteen fish species were found, that were Barbonymus gonionotus, Trichopodus trichopterus, T. pectoralis, Glossogobius giuris, Glossogobius aureus, Osteochilus vittatus, Oreochromis niloticus, Oxyeleotris marmorata, Channa striata, Anabas testudineus, Clarias batrachus, Pangasianodon hypopthalmus, Monopterus albus, Stenogobius gymnopomus, Stenogobius sp., Megalops cyprinoides, Caranx sexfasciatus, Anguilla marmorata and Liposarcus pardalis. Most of the fish are introduced fish for consumption purposes. Besides that, it was also found a new non native fish found in Lake Tempe, namely Amazon sailfin catfish (Liposarcus pardalis). The fish species that have not been found were blue panchax (Aplocheilus panchax), wrestling halfbeak (Dermogenys pusilla), dussumier’s ponyfish (Karalla dussumieri), Lagusia micrachantus, kissing gourami (Helostoma teminckii) and carp (Cyprinus carpio). Some of fish found are known to be migratory fish species that also live in brackish or marine waters, namely Anguilla marmorata, Stenogobius sp., Megalops cyprinoides, and Caranx sexfasciatus.
