Intensive Shrimp Welfare in Vietnamese Production Systems

Vietnam is one of the world's largest shrimp producers. Intensive production systems in the Mekong Delta raise significant welfare questions about stocking density, disease management and harvest practices.

Key Facts

Vietnam produces over 700,000 tonnes of shrimp annually, with black tiger prawn and whiteleg shrimp the main species
Intensive super-intensive shrimp production uses stocking densities of 200-500 post-larvae per square metre
Disease events including early mortality syndrome cause catastrophic pond losses in intensive systems
Harvest by pond draining and netting subjects shrimp to acute crowding, physical injury and heat stress
Certification systems including ASC and GlobalG.A.P. are increasingly adopted but coverage remains incomplete

Welfare Considerations

Intensive shrimp production in Vietnam imposes welfare costs through stocking densities that vastly exceed what any natural habitat can support. At densities of hundreds of individuals per square metre, social interaction, foraging space and water quality all deteriorate. Disease events including EMS cause massive rapid mortality that represents a welfare crisis for surviving and dying individuals simultaneously. Harvest procedures including pond draining and netting expose shrimp to acute thermal stress, physical contact injury and oxygen deprivation. The welfare of individual shrimp in intensive Vietnamese systems reflects the pressure of production economics that prioritise yield over animal experience.

What You Can Do

Choose Vietnamese shrimp certified to ASC or GlobalG.A.P. standards with welfare components
Support development of stronger welfare requirements in shrimp aquaculture certification
Engage with major shrimp retailers about welfare requirements in their Vietnamese supply chains
Support research into appropriate welfare indicators for whiteleg shrimp in intensive production
Advocate for aquaculture development aid to include welfare improvement components
