Farmed Shrimp Welfare and Slaughter Practices

Farmed shrimp are produced in enormous numbers with little welfare consideration, despite growing evidence of their capacity for pain and suffering.

Key Facts

Global shrimp aquaculture produces over 5 million tonnes annually, with the majority farmed in Asia
Shrimp show nociceptive responses, prolonged protective behaviour, and neurochemical changes consistent with pain experience
Most farmed shrimp are slaughtered without any stunning, by live boiling, chilling on ice, or crushing
Diseases such as Early Mortality Syndrome and White Spot Disease cause mass mortality events in crowded ponds
Welfare standards for shrimp are almost absent from current aquaculture certification schemes

Welfare Considerations

The sheer scale of shrimp production — hundreds of billions of individuals annually — combined with the absence of welfare standards makes this one of the most significant potential sources of animal suffering in the global food system. The scientific uncertainty about shrimp sentience does not justify ignoring welfare entirely. A precautionary approach would implement basic improvements including effective pre-slaughter stunning.

What You Can Do

Reduce shrimp consumption or choose suppliers committed to improving welfare standards
Support the Shrimp Welfare Project and similar organisations developing practical welfare improvements
Ask retailers about their shrimp sourcing and whether welfare standards are included in their certification requirements
Advocate for the inclusion of decapod crustaceans in national animal welfare legislation
