Global shrimp aquaculture produces over 5 million tonnes annually with minimal welfare oversight. Key welfare challenges — disease, overcrowding, ammonia stress, and slaughter methods — are increasingly subject to scientific and ethical scrutiny.
Shrimp welfare presents a high-impact, tractable opportunity for welfare improvement. The numbers are staggering — hundreds of billions of individuals annually — and current practices impose suffering that better-designed systems could substantially reduce. Disease-driven mass mortality causes prolonged suffering in affected ponds. Slaughter by ice immersion is slow. These are not welfare challenges that require technological breakthroughs to address: better water quality management, lower stocking densities, and rapid cooling systems reduce the welfare burden at the individual and population level. The Shrimp Welfare Project's work on identifying scalable interventions represents exactly the kind of evidence-based, high-impact welfare research that the field needs.
