Why are they a problem?
Introduced fish compete with native fish for food and habitat. In some cases introduced species prey directly on the larvae and fry of native species, and can have devastating effects on their population. For example Redfin are a voracious predator of small native fish.

What is being done?
Research is currently being conducted into how to best address this problem. On-ground work to eradicate Carp from River Murray wetlands is an activity that the Government has supported for the past decade, and this strategy has been very successful in the localised removal of this pest species.

What can I do?
The community can assist in these programs by becoming involved in one of the many wetland projects that are active on the River Murray. This can be undertaken by approaching your local community group or local Action Planning committees on the River.
Fishers can assist by complying to regulations that require that non-native fish are not returned to the water once captured. Furthermore, anglers and the broader community should be aware that the translocation of fish between waters is a serious and in some cases illegal activity that can lead to the establishment of feral populations. This activity should not be undertaken without the proper information and authorisation.
