This report documents the outcomes of field trials assessing carp control technologies in key wetlands of the lower Lachlan River, where European carp are a major invasive species. The study tested various carp separation cage (CSC) prototypes and manipulated flow regimes to expl...
This report outlines the environmental water requirements (EWR) for native fish communities in the Middle River catchment on Kangaroo Island. Field sampling conducted across multiple geomorphic zones identified four distinct fish community regions, including estuarine, lowland/go...
This is the fifth stock status report assessing seven key species in the South Australian Lakes and Coorong Fishery. It evaluates fishery performance from 1984–85 to 2009–10 using catch, effort, and CPUE data, comparing results against management plan reference points. The 2009–1...
This assessment updates the status of the Gulf St Vincent Prawn Fishery based on data from the 2008/09 and 2009/10 seasons. While biomass levels were higher than in 2004/05, declines in 2009/10 and a reduced proportion of large prawns raised sustainability concerns. Commercial ca...
This report provides a comprehensive summary of production volume and landed value for South Australia’s commercial wild fisheries during the 2009/10 financial year. It serves as a key resource for industry stakeholders and policymakers, offering insights into the performance of ...
This report presents the development of quantitative PCR assays for detecting three marine pests: Musculista senhousia (Asian Date Mussel), Perna canaliculus (New Zealand Greenlip Mussel), and Corbula gibba (European Clam). These molecular tools enable rapid, high-throughput scre...
This progress report presents the initial findings from ‘before’ intervention monitoring at Katfish Reach, a native fish demonstration project in South Australia. Using a BACIP design, researchers assessed fish communities and habitats across 22 sites in 2010, prior to implementi...
This report compares megafaunal biodiversity in two submarine canyons off South Australia's southern coast: the steep-sided du Couedic Canyon and the broader Bonney Canyon. Over 180 species were recorded, most of which could not be matched to known taxa, indicating high levels of...
The Chowilla floodplain system is the largest remaining area of undeveloped floodplain habitat in the lower Murray River and has been listed as a wetland of international importance under the Ramsar Convention. However, the Chowilla floodplain has become increasingly degraded as ...
Due to over abstraction, prolonged drought and subsequently reduced River Murray inflows, water levels in the Ramsar listed Lower Lakes have been receding since 2006 and reached an historical low of -1.0 m AHD in May 2009. Water level recession has had many detrimental impacts on...
