Carp Welfare in Aquaculture and Angling

Carp are among the most widely cultivated fish globally and face welfare challenges in both production and recreational angling contexts.

Key Facts

Carp production accounts for over a third of all global aquaculture production
Carp are sentient fish with evidence of pain perception and aversive learning
Winter storage of carp in low-oxygen conditions causes chronic stress
Catch-and-release carp angling is popular in Europe but carries welfare risks from hook injury and handling
Carp are considered sentient in countries including the UK under animal welfare legislation

Welfare Considerations

Carp welfare is relevant in both production and recreational angling contexts. In intensive aquaculture, poor water quality, high stocking density, and inappropriate handling cause chronic stress and pain. In recreational angling, hook injury, long fights, and inadequate handling during catch-and-release cause varying degrees of welfare harm. Welfare-conscious management in both contexts is needed.

Support aquaculture standards that include carp welfare requirements
Practice welfare-conscious catch-and-release carp angling with barbless hooks and wet hands
