Shrimp Aquaculture Welfare Challenges

Farmed shrimp production has grown enormously to meet global demand, with welfare concerns including disease-driven mass mortality, eyestalk ablation, and poor stocking conditions.

Key Facts

Global shrimp aquaculture produces over 5 million tonnes annually
Eyestalk ablation — removing one eye to induce spawning — is standard practice in breeding stock
Disease outbreaks including Early Mortality Syndrome have killed billions of shrimp and destroyed farms
Shrimp have nociceptors and show avoidance responses to harmful stimuli
The Shrimp Welfare Project works with farms to improve shrimp welfare at scale

Welfare Considerations

Shrimp welfare is an emerging area of welfare science where the stakes are enormous given the scale of production. The question of shrimp sentience is not fully resolved, but evidence of nociceptive responses and stress-related physiological changes suggests welfare consideration is warranted under the precautionary principle. Eyestalk ablation — the removal of a stalk-eye from broodstock females to induce spawning — is an acute harm performed on animals showing pain responses. Stocking conditions in ponds, water quality management, and slaughter method all represent areas where welfare improvements are being developed and implemented.

What You Can Do

Choose shrimp certified by organisations with shrimp welfare provisions
Reduce shrimp consumption pending clearer welfare standards in the industry
Support the Shrimp Welfare Project in their work with producers
Advocate for eyestalk ablation bans in farmed shrimp production standards
Raise awareness about shrimp welfare as an overlooked but significant animal welfare issue
