Tucked away in the north-west of New South Wales lies the Toorale National Park and State Conservation Area, a culturally and ecologically significant site. At the confluence of two ecologically significant rivers for the Murray Darling Basin, the Warrego and the Darling Rivers, the Toorale National Park and State Conservation Area were jointly purchased by
In August last year we introduced you to our resurrected friend, the Southern purple-spotted gudgeon (Mogurnda adspersa) aka the Zombie Fish! When we last reported, 30 Southern purple spotted gudgeon (SPSG) broodstock were collected from the newly discovered Kerang lakes population for captive breeding at Middle Creek Farm and Aquasave-NGT hatcheries. Since then, 13 potential
In the summer of 2018-19, after two years of low flows in the lower Darling Baaka River in western New South Wales, a series of three mass fish kills occurred near Menindee, resulting in the deaths of millions of native fish. The size of the fish kills was unprecedented, with millions of native Bony herring
The native Gaygay (Freshwater catfish - Tandanus tandanus) was once common across the lower Gwydir, but in recent decades, numbers have declined significantly and the species is now considered ‘rare’ in most areas. In 2015, during the Gwydir Long Term Intervention Monitoring (LTIM) sampling, only one gaygay was captured, and no gaygay were detected subsequently
The establishment of the Koondrook Weir, located in the mid-Murray River system, has limited the movement between Gunbower Creek and the Murray River for vulnerable and threatened fish species such as the Murray cod and the Golden perch. This lack of fish movement has also stunted potential developments in recreational fishing tourism for the area.
The Mid-Murray Floodplains along the New South Wales and Victorian border are home to some of the highest diversities of native fish species within the Murray-Darling Basin. Threatened and recreationally important species, like the Murray cod, golden perch, trout cod and silver perch, as well as wetland-specialist species, once thrived in the region’s interconnecting rivers,
Australia is facing a biodiversity crisis. Since 1788, according to the federal Environment and Biodiversity Protection Act, 39 of all mammal species (10%), 23 bird species, four frog species, one known fish species and 37 plant species are now extinct in Australia. Native fish, in particular, are silently bearing the brunt of increasing degradation of
The dramatic events of the summer of 2018-19, where a series of three mass fish kills resulted in the deaths of millions of native fish in the lower Darling-Baaka River, captured national and global attention. Feelings of sadness and horror at the scale of the fish kills had the media and general public, who for
How does a cold water specialist fish survive in Queensland? And why is it known as a ‘Canary in the coalmine’? There is a special fish - the River blackfish - that calls the Condamine headwaters in southern Queensland its home. This region is unique in Queensland as it has stretches of cold water that
Georges River Fish Habitat Restoration Project OzFish Hawkesbury-Nepean Chapter with Campbelltown Council have been undertaking Environmental DNA (eDNA) sampling in south-west Sydney on the Georges River to determine the presence of endangered species in the waterway. Local volunteers assist researchers and staff from council by collecting water samples in a coordinated approach at various locations
Tilapia (Oreochromis mossambicus or the Mozambique Mouth Brooder) is an introduced fish species found in Australia and many other parts of the world. The species is native to Africa and a member of the Cichlid family. It is particularly harmful to natural waterways in Australia, threatening native fish species and their habitats. World authorities consider
At the end of the Murray River in South Australia are two large freshwater lakes surrounded by biodiverse wetlands. As a part of Ngarrindjeri Country, Lake Albert and Lake Alexandrina are culturally and ecologically unique, in part due to their close proximity to the Murray estuary in the Coorong. The region is recognised as a
After 15 years of research, a new species of freshwater crayfish, Cherax latimanus or the Swamp Yabby, has been uncovered, now officially its own species. Researchers Dr Tarmo Raadik and Robert McCormack from the Arthur Rylah Institute for Environmental Research and Australian Aquatic Biological found and described the newly named species. This discovery of a
"Maps are a way of organising wonder" This quote by Peter Steinhart is spot on when it comes to this stunning map created by fish researcher and artist Dr Brendan Ebner. NSW DPI Fisheries asked Brendan to create this beautiful map of the Darling-Baaka River. Flowing rivers and deep pools are essential for healthy populations
Following trying times, native fish are bouncing back in the Baaka... We all remember those images from the mass fish deaths that occurred in summer 2018-2019 in the Lower Darling Baaka River along the Menindee town weir pool. To understand how this event impacted local fish communities, NSW DPI Fisheries has been monitoring the Lower
