Farmed Shrimp Welfare and Humane Slaughter

Shrimp are farmed at enormous scale with minimal welfare regulation, despite growing evidence of their capacity for pain and stress responses.

Key Facts

Global shrimp aquaculture produces over 4 million tonnes annually, involving billions of individual animals
Shrimp have nociceptors and show avoidance learning suggesting pain processing capacity
Eyestalk ablation - removing one eyestalk to induce spawning - is a common but potentially painful industry practice
Slaughter methods including on-ice killing may cause prolonged suffering before death
Shrimp Welfare Project advocates for rapid chilling before freezing or ice killing to reduce suffering
Current welfare standards for shrimp are largely absent globally despite the scale of farming

Welfare Considerations

The welfare status of shrimp remains scientifically uncertain but evidence of nociception and stress responses warrants precautionary consideration. The scale of shrimp farming means that if shrimp can suffer, the welfare impact is among the largest of any farmed species. The Shrimp Welfare Project's work on more humane slaughter methods demonstrates that welfare improvements are achievable at commercial scale. Consumer pressure and retailer engagement on shrimp welfare is a high-leverage intervention given the supply chain concentration.

What You Can Do
