Murray-Darling Basin's apex predator back from the brink
The Murray cod, Australia's largest freshwater fish and apex predator of the Murray-Darling Basin, has made a significant recovery after decades of decline. Conservation efforts including habitat restoration, fishing regulations, and stocking programs have contributed to rising populations in rivers and lakes across Victoria and New South Wales. However, the species still faces challenges, particularly in the ecologically troubled Darling River.
- ▪Murray cod were nearly wiped out in the 1970s due to overfishing, dam construction, and habitat degradation.
- ▪Scientific surveys and angler reports show strong population rebounds in Victoria's rivers and lakes, with some areas seeing over an 80 percent increase in cod numbers.
- ▪Over 90 percent of more than 3,500 surveyed recreational fishers support conservation measures like catch-and-release and proper fish handling.
- ▪The Darling River remains a site of ecological concern, with ongoing threats to Murray cod survival despite broader recovery trends.
- ▪Murray cod are still listed as vulnerable under Australian environmental law, though their population trend is now positive.
