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:

• could be infected with a serious or notifiable disease
• are dying in larger numbers or dying in a way you haven’t seen before

Prevent the spread of disease in fish and shellfish

You can help control the spread of disease if you:

• follow rules for imports
• perform regular monitoring to spot disease early
• contain outbreaks as quickly as possible
• use good fish husbandry practice
• follow rules when moving fish

• keep health records using the Finfish biosecurity logbook (PDF, 123KB, 7 pages)

• keep medicine records using the Aquatic animal medicine record book (PDF, 254KB, 52 pages)

• follow a biosecurity measures plan:

  • Shellfish biosecurity measures plan (PDF, 500KB, 28 pages)

  • Finfish biosecurity measures plan (PDF, 325KB, 32 pages)

  • Importer biosecurity measures plan (PDF, 244KB, 36 pages)

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)
