The City has recently partnered with Murdoch University’s Harry Butler Institute, several other local governments and the DBCA, to deliver a large-scale feral fish control initiative across urban wetlands.

This project is funded by the Australian Government’s Natural Heritage Trust under the Urban Rivers and Catchment Program and is supported by the Centre for Sustainable Aquatic Ecosystems (Murdoch University), OzFish Unlimited and local and State Government Authorities of Western Australia.

The project aims to reduce feral fish populations and investigate opportunities for reintroducing native fish species within a network of connected urban wetlands.

The initial baseline data collection has been completed and over the coming weeks, the control phase will start and continue through to March 2027.

During this phase, a combination of control methods will be employed, including electrofishing, pod trapping and fyke netting.

These activities will take place at the following wetlands in the City of Stirling:

  • Princeton Lakes
  • Roselea Lake
  • Careniup Wetland
  • Jackadder Lake
  • Lake Gwelup.

How you can help:

  • Keep clear of any boats, nets and trapping equipment
  • Help us to protect our freshwater systems and Don’t Dump that Fish! Never dump your pet fish or aquarium contents in the local waterways, drains or the ocean. Instead contact your local aquarium retailer and/or humanely and safely dispose
  • Report any pest fish you see in any freshwater system in WA to FishWatch on 1800 815 507
  • Get in touch with ‘Friends of’ volunteer groups that work with their local or state government agencies to preserve, protect and manage their local natural areas.
