Barred Galaxias (Galaxias fuscus) is a small, non-migratory freshwater fish endemic to a small range in the upper reaches of the Goulburn River system in central northern Victoria and is listed as Endangered under the Commonwealth EPBC Act 1999. The main threat to the remnant and isolated populations are predatory fish; introduced trout. All remaining populations of galaxiids are located upstream of barriers which prevent colonisation by predators, however, not all barriers are 100% effective. Within the last few years three successful translocations have occurred and a barrier has been upgraded. We have used previous predator detection, environmental and physical data, and assessment of all the known barriers, to develop a risk model to prioritise sites for continued monitoring. We demonstrate adaptive management in long-term recovery projects, and the importance of previous investment to this process to secure this species into the future.
