Disease status of fish, shellfish and crustacea in England and Wales

You must contact the Fish Health Inspectorate (FHI) immediately if you know or suspect fish or shellfish:

Reduce the spread of disease in fish and shellfish

You can help control the spread of disease if you:

  • perform regular health monitoring to spot disease early
  • contain outbreaks as quickly as possible
  • put in place and follow a biosecurity measures plan. Information on Biosecurity Measures Plans, their importance, and why they are a requirement of Authorisation. Use this page to access standardised BMP modules. Biosecurity Measure Plans - Information and Templates - GOV.UK (www.gov.uk)
  • It is a condition of authorisation that mortalities must be recorded as agreed and stated in your approved Biosecurity Measures Plan (BMP). Mortalities can be recorded in a preferred format, but it must include the date, number of mortalities, species affected, zone (if your farm is divided into zones) and cause. Acceptable formats include daily diaries, spreadsheets, biosecurity logbooks. An example of an acceptable mortality log that can be downloaded and used can be found here: Mortality_Record_Sheet_V1.0.pdf (publishing.service.gov.uk)

    • Control areas for notifiable disease outbreaks

    If a listed disease is confirmed, FHI places controls to limit the spread of disease (these are known as Confirmed Designation Notices) and where required will take steps to eradicate the disease.

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

  • get written permission from the FHI to move fish and/or shellfish and equipment (allow at least 5 working days)

    • Areas with controls in place to limit the spread of koi herpesvirus disease (KHV):
