This project investigated the extent to which trawled communities of Australia’s North-West Shelf have recovered from high levels of trawling before the exclusion of foreign fleets in 1990 and after the imposition of tight controls on trawl and trap fishing in the early 1990s. The results...
The discharge of ballast water from one port into another is not a recent phenomena, although its importance as a dispersal mechanism for marine species has only been fully realized in the last decade with increasing volumes of ballast water being discharged and more studies being carried out on the...
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 research sought to build on the experimental evidence regarding non-target species susceptibility to CyHV-3. Three species which had been previously tested, but for which additional evidence would be needed to confirm non-susceptibility included Rainbow Trout, Silver Perch and Murray Cod.
This study was undertaken by Charles Sturt University. Although there is a considerable knowledge gap in understanding the social-economic and environmental impacts of a fish kill, it is essential to recognise the risks associated with these events – especially water quality. In order to...
This study was undertaken by the Arthur Rylah Institute for the Department of Environment, Land, Water and Planning. Carp occur in a broad range of aquatic habitats (e.g. rivers, estuaries, wetlands, lakes, impoundments and
irrigation networks) and their density varies spatially and temporally...
