Presence and absence of non‐native fish species in the Wet Tropics region, Australia

Researchers have identified the presence of six non-native fish species, primarily from the families Cichlidae and Poeciliidae, in the Wet Tropics of Queensland, Australia. These species are established with self-sustaining populations, posing potential threats to the region's highly diverse native fish fauna. The study compiled 1106 records, including 346 confirmed presence records, four uncertain records for at least 13 species, and 756 absence records, through a combination of published data and expert knowledge. This comprehensive analysis highlights the need for further monitoring and management to mitigate the impacts of these invasive species on the unique biodiversity of the Wet Tropics region.
