The Murray Crayfish is the second largest freshwater crayfish in the world, and hadn't been seen in South Australia for 40 years, due to over-fishing and degradation of its preferred riverine habitat. Following the recent flooding and improvement of water quality, Nature Glenelg Trust...
For the first time in 40 years, Murray Crayfish have been released into SA waters! The Murray Crayfish is the second largest freshwater crayfish in the world and can weigh up to 2 kilograms, but has been lost from the southern extent of the Murray...
Join us for an informative session in Renmark, where you'll hear hear from scientists (including NGT's Aquasave aquatic ecology team) about how yabbies are responding to the current flooding and the future of Murray crayfish in South Australia. We will hear from: Professor Michael Geddes, who has...
Postponed due to very high river flows. The Murray Crayfish, second largest Crayfish in the world, will be showcased in a community field day at Barham, NSW on Sunday 11 September. All are welcome to attend and learn about the biology and ecology, past research,...
With the temperature dropping and the first frosts felt across south-eastern Australia, the Murray Crayfish (Euastacus armatus), second largest freshwater crayfish in the world, becomes more active. NGT has been involved in the conservation of this species for many years, including leading a genetic study...
If you like handicrafts, you've probably heard of a crafternoon (an afternoon crafting event), but have you heard of a CRAYfternoon? No? Well, we might have made the term up, but it fits perfectly for our recent working bees where our volunteers made more than...
I am currently in the last stages of my incredible Churchill Fellowship adventures. I have seen many wonderful things, walked a lot and learnt about all aspects of translocations and conservation more generally. I also met some inspiring people! This blog covers my time in...
Did you know that the second largest freshwater crayfish in the world, the Murray Crayfish (Euastacus armatus), was once widespread and abundant in the Murray River in South Australia? However, following population loss attributed to habitat degradation such as the regulation of flows and water...
Over the past four years, we have continued monitoring populations in the Murray River that had suffered significant (80% decline) population loss due to the 2010‒11 extreme blackwater event. Over that time, we have only observed a gradual increase in the abundance of affected populations,...
Fish stocking for fishery purposes is routinely undertaken, but conservation translocations remain relatively uncommon in the aquatic world (in terrestrial ecosystems however they are more widespread). On a sunny day in late July 2017, a small but important step toward the recovery of Murray crayfish...
