Sailfish are among the fastest fish in the ocean and popular sport fishing targets. Their welfare during catch-and-release fishing and as bycatch requires attention.
Catch-and-release sailfish fishing is widely promoted as conservation-friendly, but studies indicate post-release mortality rates of 10-40% depending on fight duration and handling practices. Fish that die post-release are not counted in bag limits, masking the true mortality impact. Longer fights cause greater physiological stress and higher post-release mortality. Commercial bycatch sailfish are typically discarded dead. There are no humane slaughter standards applied to sailfish killed as bycatch or in the small directed fisheries that exist.
