Farmed Shrimp Welfare and Humane Slaughter

Shrimp are farmed in enormous numbers globally, and growing evidence of their capacity for pain is driving welfare standards development in the sector.

Key Facts

Global shrimp aquaculture produces approximately 5-6 million metric tonnes annually, involving trillions of individual animals
Shrimp show nociceptive responses, learned avoidance of harmful stimuli, and behavioral changes after tissue damage
The Crustacean Compassion campaign has successfully lobbied for UK legislation extending animal welfare protections to decapod crustaceans
Common welfare concerns include high stocking densities, ammonia toxicity, disease outbreaks, and inhumane slaughter by boiling or chilling
Controlled atmosphere stunning using CO2 or chilling before slaughter is advocated as a more welfare-conscious approach
Shrimp Welfare Project is the leading organization developing welfare standards and auditing tools for shrimp aquaculture

Welfare Considerations

The shrimp farming sector operates at a scale that makes even modest welfare improvements enormously impactful in terms of number of individuals affected. The scientific consensus on shrimp sentience has shifted significantly in recent years, and industry and regulatory responses are beginning to reflect this. Supporting organizations advancing shrimp welfare standards is among the highest-leverage interventions available in aquatic animal welfare.
