Provides information and techniques to minimise the risk of spreading pests and diseases between NSW waterways.
Many fish species have been introduced into NSW waters over the past 200 years, both intentionally and accidentally. It's still happening today. These species arrive from interstate or overseas and invade marine or freshwater environments. Some species, including plants, animals and seaweeds, have established themselves in NSW and are now regarded as pests. For example, the invasive freshwater fish redfin perch Perca fluviatilis is listed as a noxious pest and is of major concern in NSW
Pest species can threaten indigenous aquatic and terrestrial life directly as predators and/or competitors for food or indirectly by altering their natural habitat. It's believed pests contribute to the decline of some threatened native species.
Introduced pathogens and parasites not detected by quarantine controls, can also threaten native biodiversity by causing diseases in native species.
Responsibility for the prevention and management of aquatic pests and diseases is shared between several State and Commonwealth government agencies. NSW DPI has responsibilities for the conservation and management of the fish and marine vegetation of NSW, and this includes the management of pest species and diseases.
