Pacific Whiteleg Shrimp Welfare in Asian Aquaculture

Pacific whiteleg shrimp is the most farmed crustacean globally. Intensive production in Asia raises significant welfare concerns about crowding, disease, and slaughter methods.

Key Facts

Global production exceeds 5 million tonnes annually, mostly from Southeast Asia
Stocking densities in intensive super-intensive systems reach 300-500 animals per square metre
Disease outbreaks including Early Mortality Syndrome cause catastrophic mortality events
Eyestalk ablation in female broodstock is standard practice to induce spawning
Shrimp are slaughtered by freezing, ice slurry, or chlorination — all without stunning

Welfare Considerations

Pacific whiteleg shrimp welfare is compromised across the production chain. Eyestalk ablation of broodstock females to induce maturation is a painful procedure performed without anaesthetic. Super-intensive stocking causes chronic crowding stress and disease vulnerability. Slaughter by ice slurry chilling is more humane than chlorination but welfare during freezing without prior stunning remains uncertain. Advancing welfare standards in shrimp aquaculture requires industry, certification, and regulatory engagement simultaneously.

What You Can Do

Choose ASC-certified or Shrimp Welfare Project-aligned shrimp products
Ask retailers about eyestalk ablation policies in their shrimp supply chains
Support the Shrimp Welfare Project working on industry welfare improvements
Reduce shrimp consumption or prioritise highest welfare sources available
