A catalogue of South Australian freshwater fishes, including new records, range extensions and translocations

Published data, recent surveys and studies of museum specimens are combined to provide a list of 84 fishes for South Australia in five drainage divisions. The list includes 58 native species (44 restricted to freshwater) and 26 alien species. Seven endemics are recognised, namely Chlamydogobius eremius (Zeitz), Chlamydogobius gloveri Larson, Craterocephalus dalhousiensis Ivanstoff & Glover, Craterocephalus eyresii (Steindachner), Craterocephalus gloveri Crowley & Ivanstoff, Mogurnda thermophila Allen & Jenkins and Neosilurus gloveri Allen & Feinberg. New records are reported for Craterocephalus stercusmuscarum ?stercusmuscarum (Günther), Galaxias truttaceus Valenciennes and Neochanna cleaveri (Scott), and a terapontid of uncertain status also is noted. Range extensions are reported for Nannoperca obscura (Klunzinger), Nannoperca australis Günther and an undescribed species of Hypseleotris, and the presence of Galaxias olidus Günther and Galaxias brevipinnis Günther in particular regions is confirmed. Possible extirpations are reported for Ambassis agassizii Steindachner, Gadopsis marmoratus Richardson, Galaxias rostratus Klunzinger, Maccullochella macquariensis (Cuvier), Macquaria australasica Cuvier, Mogurnda adspersa (Castelnau), Neochanna cleaveri and Prototroctes maraena Günther. There is need for further evaluations of fish distributions, better systematic frameworks, clarifications of conservation status, reviews of the introduction and impacts of alien species and development of protective measures for fish species and communities and their ecosystems.
