Shrimp are among the most widely farmed animals in the world, yet they are typically killed without any stunning. Growing evidence of crustacean sentience is driving calls for welfare reform.
The welfare of farmed shrimp represents one of the largest numerical animal welfare challenges given the astronomical numbers involved. The scientific debate about crustacean sentience has increasingly resolved toward acknowledging the probability of some form of pain experience in decapods, challenging the long-standing assumption that shrimp welfare does not matter. The development and commercial availability of electrical stunning equipment for crustaceans removes the primary practical objection to welfare-improving slaughter practices. The challenge now is creating regulatory frameworks, industry incentives, and consumer awareness that drive adoption of higher-welfare practices. Given the scale of shrimp production, even small improvements in slaughter welfare represent enormous aggregate reductions in animal suffering.
