Pest fish, such as tilapia and carp, can have major impacts on freshwater ecosystems and native species across NSW.
Impact of pest fish
These pest fish are a major environmental pest, impacting native species and ecosystems through predation, competition for resources and disrupting freshwater environments.
Control of pest fish
Almost all fish species are difficult to control once established, but biological control offers some hope in controlling widespread water pest species.
Taking care when disposing of unwanted fish and being aware of unusual species can lead to better protection of our community and our waterways.
The Department of Primary Industries and Regional Development (DPIRD) has advice on pest freshwater finfish including redfin perch, tilapia, carp, pearl cichlid and others. DPIRD can also help with advice and resources for aquarium owners, and how to report suspect exotic fish.

Pest control in your region
We've worked with regional pest animal committees and the community to develop regional strategic pest animal management plans in each of our 11 Local Land Services regions.
Your Regional Strategic Pest Animal Management Plan will tell you what priority pest animal pest animals you need to manage and how.
