Shrimp is the most traded seafood commodity globally, and growing evidence for shrimp sentience is prompting welfare advocates to scrutinize the conditions in which billions of shrimp are farmed and killed.
Shrimp welfare is at the frontier of the animal sentience debate. Evidence for basic nociception and stress responses in decapod crustaceans — including shrimp — has grown sufficiently to prompt precautionary welfare consideration. The UK's extension of welfare protections to decapod crustaceans reflects this scientific consensus. In shrimp aquaculture, welfare challenges include extreme stocking density, poor water quality, and slaughter methods that may cause prolonged suffering. The scale — billions of animals — makes even small improvements in per-animal welfare enormously significant.
