The Hon. Susan Close, Deputy Premier of South Australia, Minister for Climate, Environment and Water (SA), Media Release, 7 November 2023
The critically endangered southern purple-spotted gudgeon will be reintroduced to River Torrens / Karrawirra Pari today [7 November 2023] – another strong sign of the improved health of the river.
The gudgeons have been a missing part of the river system for over a century, and are being reintroduced to the Breakout Creek / Purruna Pari section, which has progressively been restored from an artificial channel to a more natural waterway.
The reintroduction is thanks to a partnership between Green Adelaide, Nature Glenelg Trust and the City of Marion, and was only possible thanks to ongoing recovery of the river, which can now effectively support the species.
The southern purple-spotted gudgeon was introduced to Oaklands Wetland a few years ago, and the success of this translocation has helped to facilitate breeding, so that they can now be re-introduced to River Torrens / Karrawirra Pari.
The fish had been declared as regionally extinct in SA in the early 1990s before the Oaklands Wetland played a key role in the recovery of the species.
This significant release into the River Torrens follows a translocation to the wetlands in 2021.

Quotes attributable to Susan Close
A revamped section of Breakout Creek / Purruna Pari will provide a home to this gudgeon and play a key role in boosting the resilience of the species as a whole.
Conservation activities as part of the redevelopment of the area, like water quality management, pest management and habitat restoration, have all assisted in making the rewilding project possible.
Quotes attributable to Kris Hanna Mayor of Marion
For two years, Oaklands Wetlands has been home to these most colourful residents.
The fish have enjoyed the Marion Council area so much, they have been breeding like crazy.
There are enough now to share with River Torrens, but I hope plenty will stay with us.
Quotes attributable to Dr Sylvia Zukowski, Nature Glenelg Trust Senior Aquatic Ecologist
These little fish were thought to be extinct in the wild in SA until a small population was found in the Murray Darling Basin in 2002.
Rescued fish were brought into a captive breeding program managed by Nature Glenelg Trust in wetlands, private dams and schools to boost numbers of the gudgeon.
We’ve managed to build populations to a point where we can allow the species to be released into the wild, including into their former historical range of the River Torrens / Karrawirra Pari.
