Farmed Carp Welfare in Asia | Animal Welfare Hub

Carp are the most farmed fish globally by volume, produced primarily in China and other Asian countries. Their welfare in extensive and intensive production systems varies enormously.

Key Facts

Carp account for nearly 40% of global aquaculture production by volume
China produces approximately 70% of the world's farmed carp
Common carp, silver carp, bighead carp, and grass carp are the primary farmed species
Polyculture systems farming multiple carp species together are common in China
Harvesting methods including pond draining and live transport raise significant welfare concerns
Carp are slaughtered predominantly by asphyxiation or live transport to market without stunning

Welfare Considerations

Carp welfare challenges are significant given production volumes in the billions of fish annually. Intensive polyculture systems can achieve high densities causing chronic stress and disease. Harvesting by pond draining concentrates fish at high density in warm, depleted water for extended periods. Live transport to market may last hours or days. Slaughter without prior stunning causes prolonged death by asphyxiation in air or on ice. Given the enormous scale of carp farming, even incremental welfare improvements translate to reduced suffering for billions of individuals. Developing and implementing welfare standards for carp requires regulatory action in major producing countries.

What You Can Do

Support aquaculture welfare research that includes carp as a priority species
Advocate for international trade standards that include fish welfare provisions
Reduce consumption of farmed carp until welfare improvements are implemented at scale
Support organizations working on fish welfare policy in major producing countries
