Carp are extensively used in both coarse angling and aquaculture; their welfare in both contexts depends on handling practices, water quality, and stress management.
Carp welfare spans two very different contexts — coarse angling where fish are caught and released, and aquaculture where they are raised for food. In angling, welfare depends on handling practices: barbless hooks, minimal air exposure, appropriate recovery before release, and water temperature awareness. In aquaculture, high stocking densities, poor water quality, and inadequate harvesting methods impose welfare costs that better management can significantly reduce. Cultural significance does not reduce the welfare consideration owed to these demonstrably stress-sensitive fish.
