How have Australian fish changed over the past few decades?

By Lucy Stuart October 20, 2023

Within the Murray Darling Basin (MDB), experts have estimated a decline in native fish abundance of ~90% since European settlement. Things such as changes to the hydrological regime, habitat degradation, river regulation and infrastructure, over-fishing, and impacts from alien species are all contributing to the ongoing decline (Koehn and Lintermans 2012; Lintermans 2013). Ongoing monitoring

The plight of Southern Pygmy Perch and the local efforts for recovery

By Lucy Stuart August 31, 2023

Once used as a common bait fish across the Murray-Darling Basin, the now threatened Southern Pygmy Perch (SPP) has now disappeared from most historically known locations. In NSW there are only three broad locations remaining located nearby the towns of Dalton, Holbrook and Albury. The upper Lachlan drainage near Dalton is the most far-north population

Monitoring and managing fishways – what happens after construction?

By Lucy Stuart August 3, 2023

Some time ago, we published an article about the fishways at the Koondrook and Cohuna weirs that were constructed in late 2021. More recently, we pondered on the development of performance standards for fishways and what a good fishway looks like. Although still in development, the researchers at Arthur Rylah Institute (ARI) have been collecting

What have the recent floods meant for the Coorong, Lower Lakes and Murray Mouth?

By Kate McKenna April 5, 2023

Recent floods flowing down the Murray River have well and truly reached the Coorong, Lower Lakes and Mouth of the Murray. All 593 openings across 5 barrages, which for the last 80 years have controlled flows at the Mouth of the Murray, were fully open over the summer, with freshwater, saltwater, fish and other creatures

What’s the go with the carp virus?

By Lucy Stuart March 6, 2023

For many of us in river and waterway management, it’s one of the most asked questions we get from family, friends and the community — “What's the go with that carp virus?” The recent flooding and subsequent explosion in carp numbers has again seen this question raised beyond just pubs and kitchen tables, to being

Why Don’t We Eat Carp in Australia?

By Lucy Stuart June 15, 2022

You may have heard the best anecdotal recipe for cooking carp: Place a fresh carp fillet in a pot of simmering water. Then add a small round stone from the river and simmer for 10 minutes or until the fish is cooked. Remove the carp from the pot and discard. Serve the hot stone. In Australia,

Controlling Carp numbers: biomass modelling to support native fish recovery

By Kate McKenna May 18, 2021

Scientists have been able to estimate the biomass and energy that the invasive Common Carp Cyprinus carpio (carp) species have absorbed and locked away from Australia’s ecosystems and food webs, reflecting the amount of energy and resources unavailable for native species. These findings are useful for tracking river and ecosystem recovery, setting appropriate management and
