Farmed shrimp production involves billions of sentient animals with evidence of pain capacity. Crowding, disease, and inhumane slaughter are major welfare concerns in a largely unregulated industry.
Farmed shrimp welfare has been largely invisible in discussions of aquaculture and food ethics, despite evidence that crustaceans can experience pain-like states. The scale of shrimp farming — billions of animals — means even a small probability of morally relevant experience implies enormous total suffering. High stocking densities cause chronic stress and disease vulnerability. Disease outbreaks cause mass mortality in which animals may suffer significant physiological distress before death. Standard slaughter — boiling alive or chilling without stunning — would be prohibited for vertebrates in most jurisdictions but faces no comparable regulation for shrimp. The Shrimp Welfare Project is pioneering welfare research and industry engagement to establish minimum welfare standards. Consumer awareness and demand for higher-welfare products is an important driver of change.
