From 1 July 2017, the Biosecurity Act 2015 and its subordinate legislation will commence. Content on this website will transition to reflect these changes.
Aquatic biosecurity is all about protecting the economy, human health and the environment from problems associated with aquatic pests, diseases and saltwater weeds.
Introduced pests and diseases pose environmental, social and economic threats by damaging the natural balance of aquatic flora and fauna.
Recreational and commercial fishers, fish farmers and ornamental fish enthusiasts all have a responsibility for managing biosecurity risks that they know about, or could reasonably be expected to know about. Examples in which you can discharge your general biosecurity duty include:
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.

The NSW DPI Aquatic Biosecurity group works closely with industry, other agencies and the community to manage all types of aquatic biosecurity risks.
