The Murray-Darling Basin (MDB) covers more than a million square kilometres, equivalent to 14 per cent of Australia’s total area. It is the 20th largest river catchment in the world (about the size of France and Spain joined together) and one of the driest.
The Murray-Darling Basin is home to 63 fish species, 51 of which are native, including the iconic Murray cod, along with smaller species such as galaxias, gudgeons, hardyheads and perch, plus many more!
The Basin also has a high proportion of alien species—13 of the 63 fish species are alien or translocated, and make up about 70 per cent of the numbers and 80–90 per cent of the biomass of fish in many of the Basin’s rivers.
Various factors have contributed to the decline in native fish numbers over the period of European settlement, and the impacts of climate change are posing an additional significant risk to several species currently and into the future. The nine major threats (historic and current) to native fish include:
The Native Fish Recovery Strategy is a joint Australian Government initiative developed in partnership with Basin state governments, Aboriginal Nations and the wider community. It sets out a program of actions involving government, communities and industries across the Basin to ‘recover native fish for future generations’.Learn More
