On the whole, fish that jump after the hookset are more entertaining than those that do not. Still, the idea of it, though sometimes effective, doesn’t make much sense for the fish. If someone were to hook me through the lip and try to pull me around by my face, the last thing I’d do is jump into the water. Where I can’t breathe.
A more learned person than me might be able to biologically vet it as part of the fight or flight process. Which brings around another thought about angling: Are we really fighting fish? Everything the fish is doing, once hooked, pertains to flight–trying to get away from the opposing force by whatever means possible. Fight has nothing to do with it.
Maybe the whole verbiage around it needs to be recalculated. “That fish gave a great flight.” Or, “that fish made a phenomenal effort to escape.” Because it’s not a binary relationship between noble adversaries, it’s a one-way transaction between hunter and hunted. With catch-and-release as an escape clause.
Regardless, I like the hunt part. And the jumps.
