The Welfare of Farmed Shrimp | Animal Welfare Hub

Shrimp farming produces the world's most traded seafood but involves welfare challenges from high density, disease management, and eyestalk ablation practices.

Key Facts

Global shrimp production exceeds 4 million tonnes annually
Eyestalk ablation — removing one eye — is used to accelerate reproduction in broodstock females
High-density farming creates ammonia and pathogen buildup causing disease outbreaks
White spot disease has destroyed entire shrimp crops costing billions of dollars
Evidence for shrimp nociception and stress responses is growing but remains contested

Welfare Considerations

Shrimp welfare is one of the most scientifically contested areas of aquatic welfare. Evidence suggests shrimp have nociceptors and show pain-avoidance learning, but their neural complexity is far below vertebrates. Eyestalk ablation — practiced without analgesia on millions of female broodstock annually — removes a sensory organ and alters hormonal function. The precautionary principle, and growing evidence for crustacean sentience, supports welfare investment even before certainty is established.

What You Can Do

Choose shrimp certified to standards that prohibit eyestalk ablation
Follow Aquatic Life Institute and Rethink Priorities research on shrimp sentience
Reduce shrimp consumption given scale of welfare uncertainty and farming conditions
Advocate for welfare standards development in shrimp aquaculture certification schemes
