Murray hardyhead is an endangered native fish that now persists in less than 15 subpopulations patchily distributed across its former range across the southern Murray-Darling Basin. The species experienced major population declines during the Millennium Drought when many sites deteriorated and became disconnected. Nick, Sylvia,...
Conservation translocations are increasingly considered necessary in the recovery of threatened species. Translocations for population restoration generally fall into two categories: Reintroduction: returning a species back to former habitat; orReinforcement: releasing into existing population to bolster numbers and/or improve genetics. Translocations can be complex, and the...
The rediscovery of Southern Purple-spotted Gudgeon in Third Reedy Lake, near Kerang, northern Victoria in 2019, marked the second time this species had apparently come 'back from the dead'. Following this discovery, fish were collected and bred by Aquasave-NGT and Middle Creek Farm before being...
Last month we let you know that the feasibility of restoration at Lake Hawdon North, near Robe SA, is being investigated through the Healthy Coorong, Healthy Basin program, and that NGT has designed baseline ecological monitoring for the project. Well, this month, monitoring got underway...
As long time readers of the Nature Glenelg Trust newsletter will know, a significant focus for our organisation is freshwater species conservation and research. These activities have been conducted under our 'Aquasave-NGT' banner since mid-2012, and continue the legacy of high quality aquatic research commenced...
Australia is home to approximately 280 species of freshwater fish, many of which occur nowhere else on the plant. Yet, many Australian freshwater fish are at risk of extinction from a range of threats, with the unprecedented summer bushfires of 2019‒20 posing considerable impact most...
Freshwater fish are important indicators of environmental change, and a long-term study by Aquasave / NGT staff recently published in the journal Landscape Ecology, illustrated how they were used to explore the benefits of the hydrological restoration of Long Swamp, the Ramsar Convention listed coastal...
There has been a hive of activity at Oaklands Wetland (south of Adelaide, SA) over the past month with introduced fish management in full swing. The ten ponds of the wetland system were drained down and then further pumped out in early April by the...
It seems a lifetime ago now, but over 66 days in 2019, I met with more than 50 experts across cities and towns in five countries (Costa Rica, USA, UK, Republic of Ireland and Sweden) as part of my Churchill Fellowship. My focus was ‘To...
Since August, we have recorded nine additional Mulloway recaptures as part of our recreational tagging program. Following the recent heavy rain and flows, a local by the name of Mark Asplin was walking along the beach near Ocean Grove last Saturday when he spotted a...
