what hook do tuna fishermen use?
Only two (4%) of the fifty-one bluefin tuna caught on circle hooks were deep-hooked. One age-4 fish had a circle hook protruding through the lumen of the anterior stomach (Figure 4). The exposed hook point ripped tissue that supports viscera in the Figure 2. Two hook types used to catch bluefin tuna: Mustad circle hooks (left) sizes 11/0 (top) and 12/0 (bottom) and Mustad #9174 straight hooks (right) sizes 6/0 (top) and 7/0 (bottom).
