Crustacean Compassion is an award-winning animal welfare organisation dedicated to the humane treatment of decapod crustaceans.   We are a group of animal welfare professionals who are shocked by the inhumane treatment of crabs, lobsters, prawns and crayfish, particularly in the food industry, given what is now known about their sentience. We founded the organisation when we heard that crabs were being sold alive fully immobilised in shrinkwrap in UK supermarkets; and that the RSPCA were powerless to act as the animals were not covered by the Animal Welfare Act 2006. Now we engage with legislators and policy makers to strengthen and enforce animal welfare law and policy; we work to persuade and enable companies to sell higher welfare products across their shellfish product ranges; and we seek to educate both the public and policy makers on the science of decapod crustacean sentience and on their humane treatment and care.


Our work is grounded in scientific evidence. Furthermore, we do not campaign against the use of decapod crustaceans as food. We welcome good practice in the food industry and merely believe that all sentient creatures deserve humane treatment, determined by the needs of their species. The sentience of any animal can never be 100% conclusively proven, but where doubt still exists alongside strong positive evidence, we believe that the benefit of the doubt should apply and simple measures should be taken to ensure that no animal suffers needlessly for our plates.

Crustacean Compassion is grateful to be able to draw upon the legal expertise of the  lawyers at the UK Centre for Animal Law.

We are the proud recipients of  a Sheila McKechnie award supported by the Esmee Fairbairn Foundation; a grant from the Centre for Effective Altruism, and the RSPCA Campaigner Award 2019
