Emerging welfare metrics for farmed shrimp assess water quality, stocking density, handling stress, and slaughter methods as the industry seeks evidence-based standards.
Shrimp welfare science has advanced rapidly as researchers document stress responses, pain-like behavior, and physiological indicators of suffering in crustaceans. The commercial scale — billions of individual animals — makes welfare improvements potentially transformative in scope. Eyestalk ablation, used routinely on broodstock females to induce reproduction, causes acute injury and ongoing sensory impairment with no anesthetic mitigation. The Shrimp Welfare Project and other organizations are working with producers to develop and implement practical welfare standards for this massively underregulated sector.
