The Golden Ticket: Understanding the role of flow on golden perch movement and population dynamics at a basin scale
Golden Perch Macquaria ambigua are a native fish species distributed widely across the lowland rivers of the Murray-Darling Basin (MDB), with the species known to undertake long-distance movements over 100s to 1000s of kilometres when unrestricted by barriers. While environmental flows are increasingly used to enhance movement of golden perch, knowledge gaps remain specific to the spatio temporal dynamics of these movements, how they are influenced by flows, and how such movements influence population dynamics at both regional and the MBD scale. In response to such, the Basin-scale fish theme’s research portfolio had a strong focus on understanding the role of flows in governing movement of golden perch across the MDB and how this movement influences the population dynamics.
