Farmed Whiteleg Shrimp Welfare Advances

Whiteleg shrimp are the most farmed crustacean globally. Growing evidence of their sentience makes welfare improvements in shrimp aquaculture an urgent priority.

Key Facts

Global whiteleg shrimp (Litopenaeus vannamei) production exceeds 5 million tonnes annually
They are farmed in intensive ponds primarily in Southeast Asia and Latin America
Evidence of nociception and pain-like responses in shrimp has grown substantially in recent years
UK law now recognizes decapod crustaceans including shrimp as sentient under the Animal Welfare Act
High stocking densities in intensive ponds cause chronic stress, disease, and aggression
Eyestalk ablation — removing eyestalks to induce spawning — is standard practice in broodstock management

Welfare Considerations

Shrimp welfare concerns center on eyestalk ablation (causing pain and hormonal disruption), extreme crowding causing disease and stress, and slaughter by boiling or freezing alive without prior stunning. The scale of shrimp production means that even modest per-animal welfare improvements affect billions of individuals. Welfare-improving alternatives include photoperiod manipulation instead of eyestalk ablation, better stocking density limits, and mechanical or electrical stunning before slaughter. Certification schemes are beginning to address these issues.

What You Can Do

Choose ASC-certified shrimp as a higher-welfare starting point
Support the Shrimp Welfare Project's work developing welfare standards for shrimp farming
Advocate for inclusion of shrimp in national animal welfare legislation in producing countries
Reduce shrimp consumption or shift to certified producers with documented welfare practices
