Emerging research into shrimp nociception, learning, and stress responses is advancing the scientific foundation for shrimp welfare standards in aquaculture production.
The advancing science of shrimp nociception and stress physiology is transforming the ethical and regulatory landscape for shrimp aquaculture. As evidence for decapod crustacean pain experience strengthens, the moral justification for maintaining current production practices without welfare consideration is eroding. The UK's inclusion of decapod crustaceans in animal welfare legislation represents a significant regulatory signal that other jurisdictions are watching. The welfare standards that will be needed to regulate an industry producing hundreds of billions of shrimp annually are far more challenging to implement than those for terrestrial farmed animals, but the scale of potential suffering if pain experience is confirmed makes this one of the highest-stakes welfare research frontiers.
