Some introduced freshwater fish species have had devastating impacts on Australia’s native freshwater fish species and other aquatic life and ecosystems. Introduced or ‘alien’ fish usually have a high rate of reproduction, broad environmental tolerances, and are difficult to manage. Prevention, preparedness, and incident response activities, (including quarantine/border control, risk assessments, training, containment, eradication) help stop new fish species from establishing populations in the wild. Waterway, biosecurity or fisheries managers can take a risk assessment approach to guide their decisions about how and when to respond to the discovery or an ‘incursion’ of a new fish species.
