Aquatic animal diseases and aquatic pests can have severe impacts on aquaculture operations. Putting systems in place to protect your farm not only helps fulfil your general biosecurity duty but makes good business sense in reducing your biosecurity risks.

Preparing for an unknown emergency event is a complex task, and preparedness is key to recover from a biosecurity threat.

Intensively cultured fish and shellfish are susceptible to bacterial, fungal, and parasitic infections, particularly at times of stress. Many problems can be avoided by ensuring stock are free of disease prior to transfer, appropriately quarantining new stock before release into culture tanks or ponds, maintaining water quality and a stress-free environment and regular disease monitoring of stock. In the event of a suspected notifiable disease outbreak, a report must be made to NSW DPI. For routine diagnostics, a veterinarian should be consulted to correctly diagnose and prescribe appropriate treatments.
