Farmed Shrimp Welfare | Animal Welfare Hub

Farmed shrimp is one of the most consumed seafood products globally, but the welfare of shrimp during farming and slaughter remains poorly understood and largely unaddressed in production and certification standards.

Key Facts

Global shrimp aquaculture produces over 5 million tonnes annually, with production centred in Asia and Latin America
Shrimp are arthropods whose capacity for pain experience is scientifically debated but increasingly taken seriously
Eyestalk ablation — removing or crushing the eyestalks of breeding females to induce spawning — is routine in the industry
Crowding in shrimp ponds causes chronic stress, increased disease susceptibility, and physical damage from aggression
Disease outbreaks including white spot syndrome virus can devastate entire farms, requiring mass mortality events
Slaughter methods for shrimp vary widely — most involve no stunning, with animals dying from suffocation on ice
The Shrimp Welfare Project is developing welfare indicators and working with producers on improved practices
Carbon dioxide stunning before killing has been proposed as a more humane slaughter method for crustaceans

Welfare Considerations

Shrimp welfare is at an early stage of scientific and industry development. The question of whether shrimp have sufficient neurological complexity to experience suffering in a morally significant way remains contested, but a precautionary welfare approach — taking potential suffering seriously given uncertainty — is gaining traction. Eyestalk ablation is one of the clearest welfare concerns: it causes demonstrable tissue damage and hormonal disruption, and alternatives are being developed. The scale of shrimp production — billions of animals per year — means that even small improvements in welfare standards translate to enormous reductions in potential suffering. Consumer demand and retailer commitments are the most tractable lever for driving industry change.

What You Can Do

Choose shrimp products from suppliers engaged with welfare improvement programmes like those of the Shrimp Welfare Project
Support the Shrimp Welfare Project and similar organisations working on evidence-based welfare standards for crustaceans
Reduce shrimp consumption from systems without welfare oversight or shift toward certified alternatives
Advocate for eyestalk ablation bans and humane slaughter requirements in shrimp aquaculture certification schemes
