By overgrazing seaweeds and sessile invertebrates, essentially back to bare rock, the advent of the long‐spined sea urchin Centrostephanus rodgersii in eastern Tasmanian waters poses a significant threat to the integrity, productivity and biodiversity of shallow (<40 m) rocky reef systems and the...
This study was undertaken by Curtin University. Wild carp (Cyprinus carpio) are an invasive species found throughout Australian freshwater systems. The species is well established throughout the Murray-Darling basin (MDB) and makes up to 90% of the fish biomass in some areas. There are concerns that...
This investigation was undertaken by the University of Adelaide and the University of Western Australia as a part of the research priorities for the National Carp Control Plan. While proposed biological control agents to reduce carp numbers may have positive impacts to aquatic ecosystems, it is...
The recruitment of fouling or pest organisms to cultured oysters and growing infrastructure imposes a major financial impost for oyster culture throughout Australia and serves as a particular deterrent to industry expansion in certain regions. Oyster farmers have a range of management options such...
Biofouling negatively affects shellfish production through several pathways, including: 1) reducing natural mussel spat settlement rates; 2) preying upon mussel spat and juveniles; 3) competing for food with mussels; and 4) smothering established mussels. These problems are well documented in the...
This project was developed by SARDI, in consultation with PIRSA, Lakes and Coorong Fishery (LCF) licence holders and relevant stakeholders, over several years. Proposals to investigate interactions with non-target species and discarding from the LCF in the Murray River estuary and Coorong...
