Farmed shrimp represent one of the largest welfare challenges in animal agriculture due to the enormous numbers involved and the emerging evidence for shrimp sentience.
Farmed shrimp welfare sits at the frontier of welfare science, policy, and ethics. The scale of individual animals involved - trillions annually - means that even small improvements in welfare conditions per animal would aggregate to enormous total welfare benefit. Eye ablation of female broodstock is a painful mutilation performed without anaesthesia to induce spawning - a practice that could be replaced by selective breeding for high reproductive performance. Chronic crowding in shrimp ponds causes stress responses measurable through cortisol-equivalent hormones. The precautionary principle applied to shrimp sentience - acknowledging that we cannot be certain shrimp do not experience suffering - justifies welfare provisions that reduce potential harm in this enormous industry.
