Abstract

Despite knowledge of potential adverse impacts arising from non-native fish introduction, economic drivers are still pushing forward for further introductions. Gozlan's pragmatic approach to this neo-paradox, allows using existing knowledge to characterise and discriminate ecological risks associated with fish species introduction. It confirms what many previously suspected, that the overall risk of adverse introduction is around ten percent. Considering all fish introductions to have the same level of risk is counter productive as it does not engage with the process of risk assessment.
