Why animal welfare is important

For the seafood sector, animal welfare relates to the handling of live animals throughout the supply chain. At some point animals destined for human consumption must be killed. Despatch can be challenging but it should always be managed in a way that ensures any unnecessary stress is avoided or reduced.

Animal welfare is an issue that the UK seafood industry takes seriously. Managing animal welfare is already a priority for many seafood businesses who have good handling and despatch processes. In addition to supporting welfare, there are also food quality and economic benefits to be gained from careful handling of the catch.

The shellfish sector is worth £565m in export revenue which includes the export of langoustines, crabs and lobster. How shellfish are treated has always been important because crabs and lobsters that are alive and in good condition attract the best price. Practices designed to reduce the stress to the animal and maximise survival are in place throughout the shellfish supply chain.

Review of sentience in cephalopods and crustaceans

Defra recognised concerns around animal welfare and sentience in relation to some species which were not included in the 2006 Animal Welfare Act. They commissioned an independent review of the evidence for sentience in cephalopod molluscs and decapod crustaceans. This review was undertaken by the London School of Economics (LSE). A final report on the review was published in November 2021.

The LSE report defines sentience as the capacity to have feelings, such as feelings of pain, pleasure, hunger, thirst, warmth, joy comfort and excitement. Researchers drew on over 300 scientific studies to evaluate evidence of sentience in:

• cephalopod molluscs – including octopods, squid and cuttlefish
• decapod crustaceans – including crabs, lobsters and crayfish

The LSE report is available on their website, you can download a pdf copy from the link below:

Following the publication of the report, Defra tabled an amendment to the Animal Welfare (Sentience) Bill. Further information on the Bill can be accessed from the UK Parliament website:

Developing best practice guidance for industry

Together with the Shellfish Association of Great Britain (SAGB) and the Crab and Lobster Management Group (CMG) we have worked with Cumulus Consultants to develop best practice guidance for the handling, storage and dispatch of live shellfish.   

The project to create the codes drew on industry knowledge and expertise across a series of industry panels that covered each key stage of the supply chain; from catching through to food service.  We also drew on the expertise of a dedicated Welfare NGO Panel.  

These codes provide:  

• Assistance to businesses – by setting out the steps they should take to minimise stress and maintain welfare. 
• Reassurance to customers and consumers – showing that due care and attention is being given to animal welfare.

We recently helped fund the publication and distribution of an advice leaflet on crustacea storage and transport produced by the SAGB. This is available digitally as a pdf from the link to their website below. Hard copies are available directly from the SAGB.
