They already do. Makes no difference. Bowfishermen at Kentucky Lake don't even put a dent in them.

The states and feds are going to have to come up with some kind of financial incentive for removal. Whether that's to just toss them into a landfill or create processing plants to create food, food substances to sell overseas, animal food, fertilizer or something else, there's no way to adequately eliminate or manage silver carp without something big.


Fur, they've tried electric barriers in the water up around Chicago in the Chicago River to keep them out of Lake Michigan. Can't remember if those work well or work better in combo with noise barriers.

But yeah, once they're in a river system IMO they're there for good. Not much that can be done.
