Shrimp Welfare: Eyestalk Ablation and Farming Conditions

Shrimp are farmed in enormous numbers under conditions that raise welfare concerns, with the controversial practice of eyestalk ablation used to accelerate reproduction.

Key Facts

Global shrimp aquaculture produces over 5 million tonnes annually
Eyestalk ablation — removing one eye — is routinely used to induce spawning in farmed shrimp
Shrimp show nociceptive responses and stress behaviours that suggest capacity for suffering
High stocking densities in shrimp ponds drive disease outbreaks and antibiotic use
Vannamei shrimp farming is concentrated in Asia and Latin America with variable welfare standards
Shrimp Welfare Project is an effective altruist organisation specifically focused on improving shrimp welfare

Welfare Considerations

Shrimp welfare has been largely ignored because shrimp are small and numerous, but evidence for their capacity for suffering is growing. Eyestalk ablation is a painful procedure performed on millions of shrimp to increase production efficiency. The Shrimp Welfare Project argues that improving shrimp welfare is among the most cost-effective interventions available given the enormous numbers involved.

What You Can Do

Support the Shrimp Welfare Project which focuses specifically on shrimp welfare improvements
Ask seafood retailers about eyestalk ablation policies in their shrimp supply chains
Advocate for shrimp welfare standards to be incorporated into aquaculture certification
Reduce shrimp consumption from uncertified conventional sources
Share information about shrimp welfare with seafood consumers who may be unaware of these practices
