Oaklands Wetlands, in the south-western suburbs of Adelaide, has been an important breeding habitat for some threatened native fish since late 2021. Southern Purple-spotted Gudgeon, which are critically endangered, were introduced here after many years of preparation (see our previous post). These colourful little fish...
Meet the southern purple spotted gudgeon, a little native fish that is critically endangered in Victoria, and has been missing in action from much of the state. In fact they were thought to be regionally extinct until some were found in a lake that was...
Maiko and Nick have been busy undertaking Environment Protection and Biodiversity Conservation (EPBC) listing assessments as part of Species Expert Assessment Plans (SEAPs) for Australian freshwater fish and spiny crayfish. Prior to these SEAPs, only 40 freshwater fish and just three spiny crayfish were listed...
Funding for the protection of freshwater biodiversity is frequently overlooked. Alarming declines in freshwater species have been observed around the globe, with population reductions of around 60% between 1970 and 2014 (Living Planet Report 2018). This has also been observed in Australia, where 88 of...
After not being seen in Adelaide wetlands for 100 years, critically endangered Southern Purple-spotted Gudgeon were released into Oaklands Wetland late last year. Oaklands Wetland underwent five years of water drawdown and alien fish elimination to make it suitable for this release (see previous post here)...
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...
