Genetic vulnerability to downriggers
I was intrigued by this blog post by Singlebarbed on a paper studying the heritability of susceptibility to angling by fish populations. It sounded interesting, so I looked up the paper.
The study was done on largemouth bass, but there is no reason to suspect that it could not be applied to other species. The authors showed that removing those fish most susceptible to angling from a population allows the less vulnerable individuals to reproduce in greater numbers. Over time, the result would be a population that is less available to anglers because of genetic traits.

For instance fish in the Big Hole and Beaverhead are more wiley than less-pressured Flathead cutthroats. But, what if there is a genetic component to that trait and it is not just a matter of the fish getting smarter?
Suppose, for instance, that you have a growing group of charter boats that consistently hammer a population of a single species of fish (say, lake trout) in the same places, using the same techniques and gear and consistently removing the largest individuals. Might we not conclude that they are removing those reproducing fish which are genetically most susceptible to their fishing strategies and over time it will become harder for them to catch fish, and especially larger fish, in those locations using that gear?
Just a theory.
