golden perch, catfish and silver perch; and the fungi Catenophlyctis and Malassizia which were found in all the larval fish species. Spawning, recruitment and origin of golden perch Hydrology From July to November 2012, flow in the lower Murray River (discharge at the South Australian border, QSA) generally reflected flow in the mid-reaches of the Murray at Euston (). In both reaches, an extended (~4 month) within-channel bank-full flow event peaked at approximately 50,000 ML day-1 in September/October 2012 before receding to approximately 20,000 ML day-1 in November 2012. Flow in the Darling River was <5,000 ML day-1 throughout this period (). Between November 2012 and March 2013, flow in the Murray River at Euston decreased to approximately 5,000 ML day-1 and flow in the Darling at Burtundy peaked at ~8,000 ML day-1 in early December 2012, but remained below 5,000 ML day-1 for the rest of the time. Flow in the Lower Murray River ranged 8–20,000 ML day-1 as a result of increasing flow from the Darling in December 2012 and water released from Lake Victoria (). Commonwealth environmental water was delivered to the SA reaches of the Murray River from October 2012–June 2013. From late October 2012 to the end of January 2013, the daily contribution of Commonwealth environmental water to flow at the South Australian border ranged ~2,000–7,300 ML, with environmental water delivery peaking at ~7,000–7,300 ML day-1 through 5–16 December 2012 (Figure 2). Details on the actual source (i.e. Lake Victoria, mid Murray River or Darling River) of this water remain unclear. Figure 19. Discharge (ML day-1) in the Murray River at the South Australian border (solid black line) and Euston (dotted black line), Darling River at Burtundy (dashed black line), Frenchman’s Creek (Lake Victoria inlet, solid red line) and Rufus River (Lake Victoria outlet, solid blue line).
