Aquaculture

Farmed Shrimp Welfare and Stocking Density

Shrimp aquaculture at high densities causes stress, disease, and poor welfare. Sustainable production systems are addressing these problems.

Key Facts

Global shrimp aquaculture produces over 5 million tonnes annually
High-density intensive ponds have disease outbreak rates far exceeding extensive systems
Shrimp show behavioral responses to noxious stimuli consistent with nociception
Crowding at stocking densities above recommended levels increases aggressive behavior
Biofloc and RAS systems allow lower stocking with improved water quality management

Welfare Considerations

Shrimp welfare is an emerging and scientifically contested area, but the precautionary principle increasingly applies as evidence of nociception accumulates. Current intensive production systems expose billions of individual animals to potential suffering through crowding, disease, and poor water quality. Systemic improvements are possible within existing technology.

What You Can Do

Choose ASC-certified shrimp which require stocking density and water quality standards
Reduce shrimp consumption given current welfare uncertainty
Advocate for welfare criteria inclusion in shrimp aquaculture certification
Support research into shrimp nociception and welfare assessment
