Farmed Shrimp Stocking Density and Welfare

Evidence on the relationship between stocking density and welfare outcomes in farmed white-leg shrimp production systems.

Key Facts

Farmed shrimp are increasingly recognized as potentially sentient animals
High stocking density correlates with increased disease pressure and mortality
Optimal stocking density varies by species, temperature, and system type
Recirculating aquaculture systems can maintain lower density with better water quality
ASC shrimp standards include stocking density limits for certified farms

Welfare Considerations

Shrimp welfare evidence is growing, with studies showing behavioral responses consistent with pain and stress. Stocking density is a key management variable affecting welfare through disease risk, oxygen levels, and social stress.

What You Can Do

Choose shrimp certified to ASC or equivalent welfare standards
Advocate for shrimp welfare science to inform production standards
Support research into shrimp sentience and welfare indicators
