Murray-Darling Basin fish monitoring survey

The Murray?Darling Basin Authority works with Queensland, New South Wales, Victoria and South Australia to monitor fish populations in 23 valleys in the Murray?Darling Basin on an annual basis. A standardised sampling protocol and randomised site selection is used to monitor species richness, size and condition of fish to report against high-level targets in the Murray?Darling Basin Plan. This dataset extends the fish component of the Sustainable Rivers Audit dataset (2004?2013).
