Shrimp Aquaculture Welfare Innovations

Shrimp aquaculture is rapidly evolving with new welfare-focused technologies. Understanding these innovations helps consumers and industry move toward better practices.

Key Facts

Global shrimp aquaculture produces over 5 million tonnes annually
Biofloc technology improves water quality and reduces disease without antibiotics
Rapid immersion chilling causes significant aversion before death - alternative methods are emerging
Recirculating aquaculture systems (RAS) for shrimp offer improved disease and welfare control
The Shrimp Welfare Project has developed the first welfare assessment framework for farmed shrimp

Welfare Considerations

Shrimp welfare innovation is accelerating following legal recognition of decapod sentience in several jurisdictions. Welfare-focused farms are adopting lower stocking densities, improved water quality monitoring and exploring humane slaughter methods. The Shrimp Welfare Project's welfare assessment tool identifies specific areas of risk including high density, poor water quality, rough handling and inhumane slaughter. Mass slaughter in ice-salt slurries causes aversion responses; electrical and CO2 alternatives are under development. Consumer certification schemes are beginning to incorporate shrimp welfare criteria.

What You Can Do

Support the Shrimp Welfare Project's farm improvement and certification programmes
Choose shrimp from ASC-certified or welfare-verified farms when available
Reduce shrimp consumption frequency given significant welfare uncertainty
Engage with retailers on adopting shrimp welfare standards across their supply chains
Support research into humane slaughter methods specifically designed for decapod crustaceans
