The Government has committed to a phased, proportionate and evidence-based approach to developing welfare arrangements for decapod crustaceans used in science.

Existing industry led welfare standards and evidence of current practice will inform this work. The initial phase includes considering and supporting appropriate baseline welfare standards, alongside voluntary reporting and further work to address evidence and technical gaps. This will support welfare improvements while building the evidence needed to inform any future consideration of including decapods as protected animals under the Animals (Scientific Procedures) Act 1986.

The Government will engage with scientific and industry representatives, animal welfare organisations and other relevant stakeholders as the work progresses. This engagement will help ensure that the approach reflects scientific evidence, existing good practice and the practical implications for those using decapods in research.

The Animal Welfare Strategy sets out Government priorities until 2030. Policies will be delivered throughout this time, including policy on decapod crustaceans.

The Government has not decided whether to extend the Animals (Scientific Procedures) Act 1986 to decapod crustaceans. The Home Office is continuing a phased, evidence-based programme of work to improve protections for decapods used in science and inform and inform any future decision on regulation.

This includes developing baseline welfare standards, voluntary reporting arrangements and identifying evidence, guidance and technical gaps. The Home Office is establishing an expert working group to support this work and is developing a roadmap setting out the key stages towards considering the potential future inclusion of decapods as protected animals under the Act.

Any decision to bring forward legislation will be informed by the evidence and advice produced. It would therefore be premature to set a date for the conclusion of that consideration. The Government will provide further updates as the work progresses through appropriate forums.

The Home Office has written to the Animals in Science Committee setting out its phased approach to developing proportionate and evidence-based arrangements for decapods used in scientific procedures. As part of this approach, the Home Office is developing a roadmap setting out objectives and key milestones to enable the development of the evidence base needed to inform future policy decisions. The Home Office will publish further information on its approach to regulating decapods used in science in due course.

The initial phase of this work focuses on the adoption of industry-led welfare standards, supported by voluntary reporting, targeted training and preparatory work. Further steps may include seeking technical advice and engaging relevant experts where appropriate.

This activity is being undertaken using existing resources and budget. As of July 2026, the Animals in Science Regulation Policy Unit has 8.6 full-time equivalent staff who support a range of priorities including policy development for decapods. The Unit collaborates with a range of other government teams to progress project activity. Resourcing arrangements will be kept under review as the policy develops.

The Home Office has committed to a phased approach to developing proportionate and evidence-based arrangements for the protections of decapods used in science. This will support welfare improvements now while further evidence is gathered to inform any future consideration of regulation.

There is merit in this approach as welfare standards can be introduced more quickly because they can build on existing good practice through voluntary standards and training and reporting, whereas regulatory standards under ASPA require further evidence, technical development and preparation before legally enforceable requirements could be introduced.

The Animal Welfare (Sentience) Act 2022 recognises decapod crustaceans as sentient beings. The Government is committed to an evidence-based and proportionate approach to their welfare, including where they are used in scientific research.

The Home Office has committed to a phased approach to developing proportionate and evidence-based arrangements for decapods used in science. This approach combines the endorsement of industry led welfare standards for decapods, supported by voluntary reporting, alongside exploring the development of a clear roadmap towards consideration of the potential future inclusion of decapods as “protected animals” under the Animals (Scientific Procedures) Act 1986 (ASPA).
