The hard slog: Progress towards a National Carp Biocontrol Program. (#97)
Evaluations of Cyprinid herpesvirus-3 as a potential biological control agent for carp in Australia continue at the high level bio-secure facility located at CSIRO’s Australian Animal Health Laboratory. Testing has shown that Australian carp are highly susceptible to the C07 strain of CyHV-3. CSIRO have now tested susceptibility of 13 representative native fish species, introduced rainbow trout and a mammal, bird and crustacean. Tests of reptiles and amphibians are currently being undertaken. No species has shown any evidence of infection. This concurs with international experience that CyHV-3-induced disease is entirely specific to common carp. The virus appears to be both effective and safe and represents a viable bio-control option for carp in Australia. Federal and state governments have been briefed on the Invasive Animals CRC’s current carp bio-control development program in preparation for submission of formal applications under the Biological Control Act, Quarantine Act/EPBC Act and APVMA Act. These applications require detailed summaries of the pest status of carp and currently available carp control options, biological and epidemiological data, details of viral production, efficacy, safety, trade, OH&S etc., as well as proposed release and M&E strategies. NSW DPI is currently in the process of compiling these data. Other activities being undertaken to advance the program are: preparation of freeze-dried virus; sequencing the genome of the C07 strain; epidemiological modelling; compilation of international data on the effects of CyHV-3; compilation/collection of benchmark data on carp densities and their environmental impacts; and, development of costings and funding proposals for a staged national carp bio-control program.
