Shrimp farming is one of the most intensive forms of aquaculture, raising welfare concerns about stocking density, water quality, and slaughter methods for billions of animals whose sentience is increasingly recognised.
The welfare status of shrimp is uncertain but the evidence is stronger than often assumed. Shrimp have nociceptors and show protective, wound-directed responses to injury. At intensive stocking densities, water quality deteriorates rapidly — high ammonia, low oxygen, and disease pressure create chronic stress. Slaughter is typically by live boiling or live chilling, neither of which guarantees rapid loss of consciousness. Given the billions of shrimp farmed, even a low probability of sentience creates enormous potential welfare stakes.
