Golden perch are perhaps the most enigmatic species in the Murray-Darling Basin (MDB). Recent advances in understanding the ecology of the species has enabled the development of a general meta-population model to examine the influence of flow on golden perch population dynamics. The model has 6 sub-populations representing the northern and southern MDB. The model is underpinned by the consultative development of a contemporary conceptual model of the flow related life history of golden perch. The model is still being refined and results are preliminary; nevertheless, the broad concepts are in place from which numerous insights are gained. For example, exploring the inter-dependence of the southern basin fish population on movement from the northern basin will be instructive concerning the overall persistence of the species and the importance of connectivity.
