Shrimp farming produces over 5 million metric tons annually, and growing scientific evidence of crustacean sentience makes the welfare of farmed shrimp an increasingly important issue.
Farmed shrimp welfare is an emerging but critical area. Evidence now strongly supports that shrimp are sentient — they learn, remember, and respond to pain in ways consistent with subjective experience. Eyestalk ablation, which mutilates broodstock to force reproduction, is a particularly concerning practice causing pain and sensory deprivation. High-density systems produce chronic stress measurable in physiological markers. Disease outbreaks causing mass mortality represent large-scale suffering events. Improvements being piloted include non-ablation breeding programs, reduced stocking densities, and improved water quality management. Given the scale — hundreds of billions of shrimp farmed annually — welfare improvements here would have enormous impact.
