Pest fish

Pest fish should never be released into waterways. They compete with local native species, which greatly reduces native fish numbers, introduces disease and parasites and affects their habitat.

A pest fish is a fish that is:

  • declared a prohibited noxious fish under Queensland legislation or;  
  • declared a restricted noxious fish under Queensland legislation or;  
  • an escaped or released ornamental fish or;  
  • an escaped or released game fish or;  
  • released native fish that is not native to that local area.  

To help us stop the spread of pest fish:

Some fish may have such negative impacts that they have been declared noxious fish under the Biosecurity Act 2014. These fish have restrictions and cannot be kept, moved, fed, given away, sold or released into the environment without a permit.

Some species must be reported to Biosecurity Queensland within 24 hours of being sighted and others must be humanely killed and disposed of. You can report a pest fish online or for more information, please contact Biosecurity Queensland on 13 25 23.
