Farmed shrimp are one of the most commonly consumed seafoods globally but face welfare challenges including overcrowding, poor water quality, and inhumane killing methods.
The sentience of shrimp is debated but evidence of nociception suggests precautionary welfare measures are appropriate. Overcrowding in ponds causes stress, disease and injuries. Eyestalk ablation is painful and performed without anaesthesia. Killing methods typically cause prolonged suffering. Certification schemes are beginning to address these issues, and consumer demand for higher-welfare shrimp can drive change.
