Jumping fish can be tricky sometimes. For example, when I am in my boat and I have nice bass that decides to jump, I actually shove my rod into the water. The bass will attempt to jump, but I take the slack out, and it just becomes a slow headshake. On the bank however depending on the type of cover you are dealing with your technique must change. For example, little to no cover I keep the rod pointing down to minimize the jumping as best as possible. If you are fishing around moderate to heavy cover, I actually exaggerate and raise my rod up to where the my reel is at shoulder level, so that I may pull the bass over the cover quickly. If you give the fish the upperhand in this situation, it will dig into the vegetation and you might lose it.
