Shrimp are farmed in enormous numbers globally with minimal welfare consideration, despite growing scientific evidence of their sentience.
Shrimp welfare occupies a particularly difficult ethical space — the scale of production is enormous, the sentience evidence is suggestive but debated, and welfare infrastructure is almost entirely absent from the industry. The precautionary principle suggests that the potential suffering of hundreds of billions of animals warrants serious action even under uncertainty. Eyestalk ablation causes demonstrable physiological stress and represents a straightforward target for reform. Water quality management improvements that benefit producer economics simultaneously reduce chronic stress for shrimp. The Shrimp Welfare Project has demonstrated that producers can adopt higher-welfare practices when provided with clear protocols and support.
