Farmed Shrimp Welfare and Intensive Aquaculture

Shrimp farming produces over 4 million tonnes annually under intensely crowded conditions with little attention to the welfare needs of animals whose sentience is increasingly recognized.

Key Facts

Global farmed shrimp production exceeds 4.5 million tonnes per year
Intensive shrimp ponds can hold 150 animals per square meter
Eyestalk ablation — removing one eye to induce spawning — is standard industry practice
Shrimp Welfare Project estimates billions of shrimp experience poor welfare in aquaculture annually
Evidence for nociception in shrimp includes avoidance learning and protective responses to injury

Welfare Considerations

Eyestalk ablation, performed without anesthetic, involves crushing or cutting the eyestalk of broodstock females to stimulate reproduction through hormone release. This causes acute injury and disrupts sensory function permanently. Beyond this single practice, shrimp aquaculture involves extreme crowding, poor water quality, disease epidemics requiring antibiotic treatment, and handling stress. The sheer scale — hundreds of billions of animals annually — means improvements in shrimp welfare could represent one of the largest potential welfare gains in animal agriculture.

What You Can Do

Support Shrimp Welfare Project financially and in advocacy
Choose shrimp certified by schemes adopting welfare standards
Reduce shrimp consumption or substitute with plant-based alternatives
Advocate for eyestalk ablation bans in farmed shrimp certification standards
