Introduced Cichlid Fish in Australian Inland Waters

Abstract

Although approximately 150 species of cichlid are regularly imported into Australia through the aquarium trade, only 3 species have to date established breeding populations in inland waters. The most widely distributed and potentially problematic species is Oreochromis mossambicus , the Mozambique mouth-brooder. The distribution and biology of O. mossambicus in Australia is reviewed outlining the practical and environmental problems that seem likely to arise should this species become more widely established. The declaration of O. mossambicus as a "noxious" species throughout Australia would discourage its interstate transport and its sale to aquarists and others in southern States, where it may currently be cultivated.
