Apply for Non-Native Fish or Crayfish Licence

CEFAS and DEFRA published updated guidance on 23 April 2026 for applying to the Fish Health Inspectorate to introduce and keep non-native freshwater fish (not for farms or inland waters) and certain non-native crayfish species. This consolidated form replaces the previous ILFA1 and CRAY2 application forms. The guidance applies to England and Wales and cites the Import of Live Fish (England and Wales) Act 1980 and the Prohibition of Keeping of Live Fish (Crayfish) Order 1996 as the governing legislation.

Exporting Live Fish, Molluscs and Crustaceans for Farming

CEFAS, DEFRA, and APHA updated guidance on exporting live fish, molluscs, and crustaceans from England and Wales. Exporters must obtain authorisation under The Aquatic Animal Health (England and Wales) Regulations 2009, including site visits within 7 working days and compliance visits within 4 weeks. EU-bound exports must also comply with Commission Implementing Regulation (EU) 2020/2236.

Apply to List Aquaculture Disinfectants, View Products

CEFAS and Defra updated guidance on the voluntary aquaculture disinfectant listing scheme, which validates disinfectants against aquatic viral and bacterial diseases. Seven products are currently listed with their effective dilutions. Disinfectant manufacturers may apply by submitting test results from qualified laboratories and completing the required application forms.

Apply to Use Nets, Traps, or Electric Fishing Instruments in English Inland Waters

The Environment Agency, CEFAS, and Defra have published guidance on obtaining written permission to use nets, traps, or electric fishing instruments in English inland waters including canals, rivers, streams, lakes, and ponds. Applications require details on timing, fishing instruments, site location with national grid reference, water type and size, conservation designations, and species to be removed. Decisions take up to 25 working days, or longer for protected areas. Authorisation does not permit removal of fish from private waters without the owner's permission.

KHV Outbreaks Found in England and Wales, 2025

The Fish Health Inspectorate (FHI) has reported Koi herpesvirus (KHV) disease outbreaks at multiple sites in England and Wales during 2025. KHV is a serious viral disease affecting carp species that can cause large-scale mortalities. Confirmed designation controls have been placed on affected sites, including movement restrictions and disposal requirements for mortalities. Fish keepers are advised to monitor for signs of KHV and report suspected outbreaks to the FHI immediately.
