I&I NSW is commonly asked by farmers how to eliminate carp from private farm dams.

To help answer this question, the Aquatic Biosecurity Unit has developed a new Primefact Carp in farm dams. This Primefact outlines methods landholders can try to eradicate carp from their farm dam.

Eradication of carp from farm dams is very difficult. There are several factors to take into consideration to determine if eradication is feasible, including if the dam is suitably located and designed for draining.

It is also critical to ensure that any carp do not get released into local waterways or create pollution or animal welfare problems.

The Primefact also provides information on methods to reduce numbers of carp in the dam.

Note: Careful consideration must be given to the potential impact on native fish and other flora and fauna when implementing the draining and drying method, especially in wetland areas and associated water bodies where acid sulphate soils are know to occur. Draining and drying may require the completion of a review of environmental factors (REF) and/or a permit; therefore local agencies must be consulted regarding any requirements before attempting this method.
