    Cichlids are a popular aquarium fish that pose potential risk to native fish populations. In 2006 highly invasive feral cichlids were found in Bennett Brook, a tributary of the Swan River. In 2009 they were reported in the Swan River.

    With funding from the State NRM Program, the Swan River Trust investigated the prevalence and breeding success of cichlids in the Swan-Canning river system. Information from this investigation was used to identify the threat cichlids pose to native fish populations and to inform future management options.

    This project was extended in 2012 with the aim of eradicating pearl cichlids from the catchment of the Swan Canning Riverpark. The focus of activity will initially be on the Altone Lakes, which were identified as the main recruitment source.

    The Swan River Trust will work closely with Murdoch University (delivering project 10004), the Department of Fisheries and the City of Swan to deliver this project.

    Investment: $ 75 000
    Delivery organisation: Swan River Trust
    Project duration: November 2009 - June 2013
    Location: Upper Swan River and tributaries
