Farmed Freshwater Prawn Welfare | Animal Welfare Hub

Freshwater prawn farming is expanding in Asia and beyond. Welfare science for these decapod crustaceans is developing alongside the UK's legal recognition of their sentience.

Key Facts

Giant freshwater prawns (Macrobrachium rosenbergii) are farmed in South and Southeast Asia producing over 200,000 tonnes annually
The UK Sentience Act 2022 recognised decapod crustaceans including prawns as sentient, with welfare implications for farming
Freshwater prawns show complex social hierarchies with dominant males controlling female access in large harems
Crowding stress in intensive prawn culture causes elevated cortisol equivalents and increased vulnerability to disease
Slaughter methods for freshwater prawns are almost entirely unregulated globally, with live boiling remaining common
Water quality management is critical; poor oxygen, pH, and temperature control causes chronic physiological stress

Welfare Considerations

Freshwater prawn welfare exists in the same regulatory gap as marine shrimp welfare - legally recognised sentience but virtually no welfare standards in production. As production scales to meet global protein demand, establishing welfare-positive practices from the outset is more achievable than reform of an established low-welfare industry. The biological evidence for prawn sentience is strong enough to justify precautionary welfare protection. Consumers who care about animal welfare should apply the same scrutiny to prawn sourcing that they apply to other animal products.

What You Can Do

Support campaigns for decapod welfare regulations to match the UK's legal recognition of their sentience
Advocate for humane slaughter requirements for all decapod crustaceans in commercial production
Reduce prawn consumption while welfare standards in the sector develop
Support research into welfare-positive slaughter methods for prawns and other crustaceans
