I found this question intriguing enough to research (Okay, Google and Wiki are kind of like research).
I wanted to see if tiger trout would help, but places out west actually use them to eradicate brook trout. Then I saw this Outdoor Life article about how a super-male brook trout was developed in Idaho to mitigate impact on western native trout populations.
"The wildlife agency’s answer to these questions is the “super male”, which is a male brook trout that has two Y chromosomes instead of the usual XY arrangement. The effect of this change is that fish with two Y chromosomes can still fertilize eggs from females, but this fertilization will only produce male offspring."
The article is ~ 2 years old and I don't know if success has been measured yet.
Could it be possible to modify brown trout in a similar manner to make an all-male, and eventually a non-breeding population of brown trout in wild brook trout water?
A catch-and-kill brown trout policy could eventually be implemented in the test location to keep the meat fishers happy (no hole-bleaching please).

Idaho Hatches Plan to Help Native Trout by Introducing "Super-Male" Brook Trout
Idaho is implementing an experimental new strategy with "super-male" brook trout in its effort to eradicate brookies from certain watersheds.
