Shrimp aquaculture produces over 5 million tonnes annually and involves complex welfare questions about crustacean sentience alongside documented welfare problems related to crowding and disease.
Farmed shrimp welfare combines genuine scientific uncertainty about sentience with practices that are clearly problematic if shrimp do experience pain. Eyestalk ablation, which involves crushing or cutting off the eyestalk of female broodstock to stimulate maturation, causes tissue damage and behavioral responses consistent with pain — this practice is performed on hundreds of millions of shrimp annually. Disease management practices including rapid crowding for treatment and mass disposal of diseased stocks involve acute stress. Slaughter by live icing or live boiling may involve significant suffering if shrimp are sentient. The scientific consensus has shifted toward taking shrimp sentience seriously following the 2021 LSE review, which underpins UK law now extending animal sentience protections to decapods. Shrimp welfare certification standards are in development through the Aquatic Life Institute and represent an important emerging area.
