Shrimp welfare has been largely ignored in aquaculture, but growing evidence of crustacean sentience and consumer pressure is beginning to change industry practices.
Shrimp welfare represents one of the most significant unaddressed welfare challenges in global food production. Shrimp are produced at enormous scale with minimal welfare consideration. The emerging evidence of sentience — while not definitive — is sufficient to justify precautionary welfare standards. Progress is beginning: some certification schemes include basic welfare criteria, some producers are exploring pre-slaughter stunning, and consumer demand for certified sustainable shrimp is creating market incentives for improved practices. The scale of shrimp production means that even modest welfare improvements per animal translate to enormous aggregate reductions in potential suffering.
