Farmed Animals

Farmed Carp Aquaculture Welfare

Carp are the most widely farmed fish globally by volume, yet welfare standards for their production remain largely underdeveloped relative to their scale.

Key Facts

Global carp production exceeds 30 million tonnes annually - more than all other farmed fish combined
Common carp, silver carp, bighead carp, and grass carp are the main farmed species
Carp are highly adaptable and can tolerate a wide range of environmental conditions
Stocking densities in pond culture vary enormously with welfare implications at high densities
Carp have well-developed pain responses and learning capabilities consistent with sentience

Welfare Considerations

Despite their enormous numbers, carp receive almost no welfare attention compared to salmon or even shrimp. High-density pond culture can cause oxygen depletion, stress, and disease. Slaughter methods including ice slurry and live transport over long distances are rarely assessed for welfare. The sheer scale of carp farming - hundreds of billions of animals - means even marginal welfare improvements would have enormous impact.

What You Can Do

Advocate for welfare standards to be developed for carp aquaculture as a priority given scale
Support research into carp sentience and appropriate welfare indicators
Choose carp products from operations with documented low stocking densities where available
Raise awareness about carp as a neglected welfare issue in aquaculture advocacy
