Aquaculture

Farmed Carp Water Quality and Welfare

Carp are the world's most farmed fish, but welfare standards in carp production lag far behind salmonid farming in most countries.

Key Facts

Common carp production exceeds 4 million tonnes annually, mostly in Asia
Carp tolerate low oxygen levels but suffer welfare impacts at extremes
Traditional pond systems often have poor water quality management
Stocking densities in intensive carp systems can exceed welfare limits
Carp sentience evidence is comparable to other farmed fish species

Welfare Considerations

Carp welfare is often overlooked despite their numerical dominance in aquaculture. Poor water quality causes chronic stress and disease. The growing body of evidence for carp sentience, including pain perception, strengthens the case for improved welfare standards.
