Farmed shrimp production involves billions of individual animals with increasing evidence of sentience. This emerging welfare frontier raises important questions about aquaculture practices.
Farmed shrimp welfare represents one of the most challenging frontiers in animal welfare, combining genuine scientific uncertainty about the depth of shrimp experience with enormous scale. If shrimp experience any meaningful degree of suffering, the numbers involved in aquaculture make this one of the most significant welfare issues numerically. High stocking densities, poor water quality, eyestalk ablation, and inhumane slaughter methods are documented in shrimp farming systems globally. The recognition of decapod sentience in UK legislation is an important step toward taking shrimp welfare seriously. Given uncertainty about sentience, caution and the precautionary principle support welfare improvements.
