Someone snagged by a fishhook should cut the line and, if possible, let a doctor remove the hook from the flesh. In the back country you may have to do the job yourself:
1: Push the hook farther in until the barb comes through the skin. 2: Snip off the barb with pliers, wire cutters, or nail clippers. 3: Ease the shank of the hook back out through the point of entry. 4: Wash and bandage the wound. — The Official Boy Scout Handbook Eleventh Edition, 1998
