Tricky Fish

Sometimes you will encounter a fish that plays badly, but bluffs and semi-bluffs in decent places (maybe a bit too much). It has been said that if an opponents bluffs too much, you should induce more bluffs from him. However, I like my opponents to play as straightforward as possible so my decisions are as easy as possible.

The question is:
Is it +EV to say things to a fish in order to reduce his bluffing frequency, so that his game is reduced to merely his bare poor play?
