Prevent fish or shellfish diseases

Reduce the risk of disease, find out where notifiable diseases have been found and what to do if your fish or shellfish have a disease.

Each year thousands of fish and shellfish die from disease. Recovering from an outbreak can take a long time and can be very expensive.

Serious fish and shellfish diseases

You must tell the Fish Health Inspectorate (FHI) if fish or shellfish:

Prevent the spread of disease in fish and shellfish

You can help control the spread of disease if you:

Control areas for notifiable disease outbreaks

If a notifiable disease is found, FHI puts controls in place to limit the spread of disease (these areas are known as confirmed designations).

If your fish or shellfish are in a control area you must:

  • comply with any conditions issued by FHI
  • get written permission from FHI to move fish or equipment (allow at least 5 working days)
