What you can do to help

Koi hobbyists and breeders

Only keep koi in places (garden ponds and other outdoor containers) where they cannot escape into natural waterways.

Remember that it is illegal to stock carp into streams, rivers or lakes in NSW and fines of up to $11,000 apply.
Do not use live carp as bait. The use of live carp as bait in freshwater is illegal and carries a high probability of infesting new areas with carp.
Ensure your boat and trailer are free of weed before re-launching to avoid the possibility of spreading carp eggs and juveniles.
Take part in native fish restocking programs with your local angling group, and support recreational fishing for carp in your area.

Manage your land in a way that reduces damage to natural waterways, for example by restricting stock access to stream banks and conserving or restoring riparian vegetation.

Assist efforts to restore our rivers (which can help native fauna to out-compete carp) by taking part in a Rivercare, Landcare or Waterwatch project.
Support the commercial harvesting of carp by purchasing products such as carp-based fertilisers or pet food.
