Investigations Into the application of Australian methods for the control and management of carp (Cyprinus carpio) in New Zealand


Report: TR 2004/03

Author: Johlene Kelly


The purpose of this study was to investigate the potential and feasibility of using techniques developed by Australian agencies as a means of managing and controlling Carp here in New Zealand. This study was made possible with the support of both the Queen Elizabeth II Technicians’ study award and the Biosecurity Group of Waikato Regional Council.

The study focused on working with various agencies within the states of Victoria, Tasmania and Queensland with particular emphasis on investigating similar situations that have parallels here in the Waikato region.

The major project objective is to apply this knowledge to the Waikato region by seeking opportunities for achieving control and/or eradication within unrestricted waterways. The outcomes generated by this project are designed to enhance Waikato Regional Council's capacity and involvement in management of Carp issues within the Waikato region as well as enhance knowledge on a national scale.
