Carp control in the River Murray

CSIRO is investigating the possible use of a specific fish virus as a biological control agent for European carp. Rigorous testing is underway to determine the safety and effectiveness of the virus Cyprinid herpesvirus 3 (CyHV – 3).

This virus does kill carp very quickly and research has shown that the virus does not develop in native Australian or any other introduced species of fish. Although it is likely to be two or three years before all approvals are granted for this project to proceed, the introduction of a virus to kill carp has the potential to create amazing recovery along the river.

A trial site established in NSW shows that the removal of the carp from a defined area has produced clear water and high visibility of the river bed from aerial photography. Over the next few months the Tri – State Alliance, a partnership of Natural Resource Management bodies in SA, Vic and NSW that includes the South Australian Murray-Darling Basin Natural Resources Management  Board and Department of Environment, Water and Natural Resources, will work through the support required to facilitate the effective implementation of river recovery after release of the virus.
