The Murray crayfish is the world's second largest freshwater crayfish - a species that naturally occurs across the southern Murray-Darling Basin. The species is closely related to the Glenelg Spiny Crayfish and faces similar threats to long-term viability. Both species have undergone considerable declines in distribution...
Chris Bice (SARDI) and I recently undertook monitoring of threatened fish communities around the Lower Lakes, as part of a project funded by the CLLMM group of DEWNR (as part of the SA Governments Murray Futures program and the Australian Governments Water for the Future...
To recognise the strong focus of Aquasave on native fish conservation, the NGT website now has a dedicated section (accessed from the "our work" tab on the homepage), which includes: an online version of the Action Plan for SA Freshwater Fishes specific areas of focus such as the...
Scientists are increasingly relying on genetic studies to help them correctly describe and classify species. Sometimes genetic analysis techniques are used as a way of ensuring that a newly discovered population of a species is correctly assigned, but wider studies are also increasingly being used...
[caption id="attachment_4869" align="alignright" width="300"] One of the few variegated pygmy perch sampled in Dec 2013[/caption] Recent condition monitoring – funded by DEWNR – has highlighted some (more) concerns for the South Australian populations of Glenelg Spiny Crayfish and the small-bodied native fish species, variegated pygmy perch....
As you may know, NGT has a strong interest in wetland and waterway conservation and management, and we have particular focus on, and expertise in, the conservation of native freshwater fish (via our Aquasave work). Not only are many species of native freshwater fish threatened...
I recently undertook a fish survey – for DEWNR, funded through the Australian Government – across the Piccaninnie Ponds system (following on from annual sampling in 2011, 2012). The survey assessed the status of fish species across the diverse range of habitats and, specifically, explored...
The Lower Lakes and Eastern Mount Lofty Ranges (EMLR) regions harbour a diverse and unique native fish community. Yet, as the recent millennium drought intensified (over 2007 to 2010), significantly diminished freshwater inflows and critical water shortages placed these regions on the verge of ecological collapse. Over...
