Aquaculture Welfare

Farmed Carp Welfare Intensive Systems

Carp farming is one of the oldest forms of aquaculture and one of the highest-volume globally, with welfare implications in intensive polyculture systems.

Key Facts

Global carp production exceeds 35 million tonnes annually from freshwater systems
Intensive carp ponds can become hypoxic during warm nights requiring emergency aeration
Carp experience handling stress and pain responses consistent with other teleost fish
Harvesting methods including rapid draining of ponds cause severe crowding stress
Welfare research on carp lags behind salmonid welfare science significantly

Welfare Considerations

Carp welfare at the scale of global production represents one of the largest unaddressed welfare challenges in aquaculture. Basic welfare measures including oxygen management, gentle harvesting, and effective slaughter could reduce suffering for billions of fish annually.
