The common rudd is a popular angling and ornamental pond fish and its welfare in handling during fishing and transport is relevant to large numbers of fish across Europe.
Angling causes acute welfare impacts from hook injuries, exhaustion from fighting, and air exposure during handling and photographing. Scale loss during rough handling impairs osmoregulation and increases infection risk. Welfare best practice for catch-and-release includes using barbless hooks, minimising air exposure, supporting the fish in water during unhooking, and releasing fish with minimal handling.
