Prawn and Shrimp Aquaculture in Asia: Welfare and Sustainability

Asian shrimp aquaculture dominates global production but has been associated with mangrove destruction, disease, and poor welfare standards. Reform programs are improving practices in some producing countries.

Key Facts

Asia produces approximately 90% of the world's farmed shrimp, with Thailand, Vietnam, Indonesia, India, and China as leading producers.
Mangrove deforestation for shrimp ponds has destroyed some of the most biodiverse coastal ecosystems globally.
Eyestalk ablation — removing the eye of female broodstock to induce spawning — is widely practiced and causes significant pain.
White Spot Syndrome Virus has repeatedly devastated shrimp farming operations across Asia.
ASC (Aquaculture Stewardship Council) shrimp certification includes environmental standards but minimal welfare provisions.

Welfare Considerations

Asian shrimp aquaculture welfare challenges include eyestalk ablation for broodstock management, high-density rearing stress, and conventional killing methods that cause prolonged suffering if shrimp are sentient. Eyestalk ablation is one of the clearest welfare violations in aquaculture — it removes the eye and associated hormonal tissue from conscious female shrimp without analgesia. Alternatives including environmental stimulation of spawning exist but are less economically efficient. The recognition of decapod crustacean sentience in UK law creates a reference point for welfare reform even if enforcement is limited to UK-sourced animals.

What You Can Do

Choose shrimp with ASC certification as a minimum standard, and advocate for welfare provisions in that scheme.
Reduce shrimp consumption given the combined welfare and environmental concerns.
Support Crustacean Compassion campaigns against eyestalk ablation.
Advocate for welfare standards for shrimp to be included in seafood import requirements.
Follow the Fish Welfare Initiative's developing work on shrimp welfare standards.
