Squid baiting method used in the experiments. Squid bait was the primary bait used in the experiments and was used on all hook types. Squid used in the experiments were 150 to 250 gram weight. The experimental procedure was to present turtles a baited hook. The turtle response was recorded by an observer as four categories. The categories were: 1. Did not take the hook into mouth. 2. Took the hook partially into mouth. 3. Took the hook fully into mouth. 4. Attempted to swallow the hook. Turtles were observed carefully by the researchers and once the hook was fully in the mouth and the turtle continued to swallow the bait, the hook and bait were pulled out of the mouth. Turtles were not allowed to actually swallow the hook. Aparejo con carnada de calamar
