Farmed Shrimp Welfare in Southeast Asian Aquaculture

Shrimp farming is one of the largest aquaculture sectors globally, with significant welfare questions about the sentience of shrimp and the conditions of industrial production in key producing countries.

Key Facts

Global shrimp aquaculture produces over 5 million tonnes annually, mostly in Southeast Asia
Eyestalk ablation — removing the eyestalks of female shrimp to induce spawning — is nearly universal in farmed shrimp production
Shrimp show nociceptive responses and protective behaviours after injury, suggesting pain capacity
Stocking densities in intensive shrimp ponds can cause chronic stress, disease, and high mortality
The UK and some European retailers have adopted policies opposing eyestalk ablation, but global uptake is minimal

Welfare Considerations

Shrimp welfare is a frontier issue where the science of invertebrate sentience is advancing faster than industry standards. Eyestalk ablation is performed on millions of broodstock shrimp annually without anaesthesia: it is a traumatic procedure that removes sense organs and alters hormonal and neurological function. The evidence that shrimp have nociceptive systems capable of registering this harm as painful is growing. At scale — trillions of shrimp produced annually — even small improvements in welfare per individual aggregate to enormous reductions in total suffering. Certification schemes that prohibit eyestalk ablation and require improved stocking density standards represent meaningful progress.

What You Can Do

Choose shrimp from suppliers certified to prohibit eyestalk ablation
Ask retailers and restaurants about their shrimp welfare sourcing standards
Support regulatory reforms requiring anaesthesia or prohibiting eyestalk ablation in shrimp farming
Reduce shrimp consumption or choose certified alternatives given limited high-welfare options
