Since the discussion came up regarding the best way to keep a flathead that you plan to release, I figured to show my method for roping a flathead. 1. Using a soft rope, tie an overhead loop in the tag end of the line. The illustration shows an inexpensive rope stringer commonly found. Rolling a flathead on their back will usually make them more docile. *Do not use the metal loop of the stringer. This is weak to begin with and rusts over time. 2. Run the lead end of the rope through the inside opening of the gills (left or right) insuring the rope is inside the gill rakers. 3. Run the lead end of the rope through the loop you tied in the tag end. 4. Tie a square knot with the tag end tied into the loop. Make sure the loop holding the fish is loose enough that the rope does not pull on the gills. 5. Tie the fish in deep enough water that it can be covered with water. If you tie them to a boat they will usually go under the boat to feel safer with overhead cover. Do not tie 2 or more fish where they can entangle each other. Watch for objects on boats that can entangle fish. Motors-transducers-anchor ropes.
