IDEAL breeding conditions over the past few seasons have seen European carp numbers balloon, particularly in the Murray-Darling Basin, causing significant environmental damage to our waterways.
State and territory governments are responsible for day-to-day carp management, but current management methods have not led to substantial reduction in numbers.
The European carp (Cyprinus carpio) is considered one of Australia’s worst freshwater pests.
Natural outbreaks of a carp virus (Cyprinid herpesvirus-3) overseas led Australian researchers to investigate using the virus as a biocontrol agent.
In 2016, the Australian Government invested $15 million to explore the feasibility of using the carp virus to manage carp populations.

In November 2022, the National Carp Control Plan (NCCP) was released suggesting the virus could reduce Australian carp populations by 40-80%.
However, several research gaps were identified and in 2023, Australian Agriculture Ministers approved additional research to be undertaken.
The Department of Agriculture, Fisheries and Forestry is coordinating a carp virus research program to address important issues such as the possibility of infection of native or non-target species, ideal conditions for virus transition between carp, overall effectiveness of the virus and other environmental impacts.
Scientific and technical advice for this research is provided by the Carp Scientific Advisory Group, a representative body of scientific experts.
Dr Bertie Hennecke, Australia’s Chief Environmental Biosecurity Officer, said the Carp Biocontrol Program is based on robust legislation and evidence-based decision-making and is in keeping with Australia’s reputation as a world leader in developing safe and effective biocontrol.
“These important steps form the cornerstones of a successful biocontrol program,” Dr Hennecke said.
"Several knowledge gaps must be addressed before a decision to release the carp virus can be made.
“This next phase of research and risk assessment is expected to take approximately 2-3 years.
"These assessments must use the best available data and evidence to ensure the best decision is made for Australia’s people and environment.”
