Farmed shrimp represent one of the largest-scale animal agriculture sectors with almost no welfare standards. Evidence for shrimp sentience and the welfare implications of current practices are increasingly scrutinized.
Shrimp welfare sits at the frontier of animal welfare science. The evidence for shrimp sentience is contested but growing — behavioral and neurobiological evidence suggests capacity for nociception at minimum. Given the enormous scale of shrimp production and consumption, even modest probability of suffering represents a significant welfare concern under the precautionary principle. Rapid ice stunning before killing is a low-cost improvement being advocated by welfare organizations. Consumer and certification pressure is beginning to drive minimal welfare improvements in this previously welfare-blind sector.
