Predators will benefit because there will be much more food to eat.
This whole tread does not make sense, you're trying to get a reaction from people who knew about this problem from begining. Why would they be silent about this for more than a decade???
This is starting to look like a story of don qUixote, with sundance in a lead role. Is there really a point in fighting a battle thats already lost?
You cannot erradicate brook trout which is way easier to catch and locate, or how about losing battle with perch? Why don't you introduce rotenone to lake sundance if it so effective against invaders? Kill those perch already!
A lot of effort has gone into containing and controling of prussian carp in entire europe. In over 50 years no one succeeded, and prussian carp is still dominant in most warmwAter bodies. Same goes for sunfish and american bull catfish.
Some things just cannot be controled by a man, get over it.
