The vast amount of money wasted on the electronic gate should now be used as a bounty for the fish...Coyotes were nearly wiped out from that lone incentive at one time and it would go a long way to controlling this species too.
I respectfully disagree with your Rainman. I've seen a bounty on common carp in a reservoir in my area that had virtually no effect on the common carp, which are easier to catch. Of course that was angling and not nets. I just don't think you can compare a prolific fish that produces thousands of eggs per female to coyotes.
BTW, it was a 700 acre reservoir with over 300 lbs. of carp per acre. You do the math.
