The TPWD study showed that bass hooked in the tongue and esophagus had about a 50 percent chance of dying, while bass hooked in the lips mouth, jaw, roof of mouth had 25 percent or less mortality. Interestingly, only 12.5 percent of gill hooked fish died. TPWD also compared the survival of bass when they were bleeding and when leaders were cut and hooks left in the fish. Removing hooks improved bass survival when bass were not bleeding. But there was little difference in mortality when bass were bleeding or hooks were left in the fish.
Fish caught with only superficial wounds are likely to survive release.
Small, deeply-hooked and bleeding bass likely should be eaten, rather than released to die later. But lunker bass are so valuable that they should be immediately released, even if they are bleeding or deeply-hooked. Remove the hook if posible. Leave an 18-inch leader if you can not remove the hook. Ralph Manns Author Information.
