Shark finning — removing fins and discarding live sharks at sea — causes extreme suffering and has devastated shark populations globally.
Finning causes one of the most prolonged and distressing deaths documented in commercial fishing. A de-finned shark returned to the ocean alive cannot swim or breathe effectively and dies slowly over hours. This practice combines maximal welfare harm with ecological devastation. It continues because fins are valuable and sharks are not charismatic enough to attract consistent enforcement attention.
