Farmed Shrimp Eye Stalk Ablation Phase-Out

Eye stalk ablation to induce maturation in farmed shrimp is a painful procedure that welfare-conscious producers are phasing out.

Key Facts

Ablation removes one eye stalk, inducing gonadal maturation in female broodstock
The procedure causes pain and permanent sensory impairment in affected shrimp
Alternative maturation induction through nutrition and environmental manipulation shows promise
Some certified sustainable shrimp standards are requiring phase-out timelines for ablation
Consumer pressure is driving change faster than regulation in some markets

Welfare Considerations

Eye stalk ablation causes pain and permanent mutilation in shrimp that show clear nociceptive responses. Feasible alternatives are being developed. Until phase-out is complete, ablation represents a welfare failure in certified sustainable shrimp production.

What You Can Do

Choose shrimp certified under standards requiring ablation phase-out plans
Support the Shrimp Welfare Project and similar organizations advocating for change
Ask retailers about ablation policies in their shrimp supply chains
