More than 450 people braved the hot and windy conditions to become citizen scientists during The Great Goolwa Cockle Challenge on Saturday. The mission was to find as many of the 2500 uniquely tagged cockles that were released prior to the event. In a great result,...
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...
With the impacts (and fishing closures) occurring in New South Wales, Victoria now maintains the geographically largest recreational fishery for the species. With this in mind, it is timely that we have just finalised the most comprehensive assessment of the Victorian recreational fishery in Victoria ever...
After four years of searching, which included over 7700 net hours (number of nets per site times by the number of hours each net was set for - that’s also 321 net days), at almost 30 sites we have failed to detect a single Murray crayfish...
Our monitoring of freshwater fish in autumn was covered by Channel Ten's "Scope TV" show, as they were interested in finding out how environmental flows and fish ladders are helping native species return to the River Torrens. In conjunction with our autumn Western Mt Lofty Ranges...
On the last day of our autumn field season, we released 3250 of the nationally endangered Murray hardyhead into Rocky Gully, a Lower Murray floodplain wetland where the species once thrived. In South Australia, this small-bodied and salt tolerant species is considered critically endangered surviving as...
We are underway with fish sampling for a number of projects across the Mt Lofty Ranges and Lower Lakes. Over the next two and a half months we will visit over 100 sites collecting data on the condition of (a) fish communities across the Eastern Mt Lofty...
Freshwater crayfish are poor dispersers – predominately moving by crawling across the bottom of rivers and creeks – so it is hard to imagine that individuals, separated by over 2000kms of waterways, can be genetically similar and form part of a single interbreeding grouping. These...
