The young carp do make for good forage fish, but once they get too large they are untouchable. since you can not "Kill" the lake and start over your only option really is to have a removal plan. Start a neighborhood carp fishing contest with the kids and any other activies that will remove the large carp out. electro fishing could help just get as many of those things out as possible. Ubfortunatly it will have to be an ongoing thing to help maintain lower numbers once are finally able to get that done. Maybe Hybrid tiger musky wold help as they grow a little faster and get a litle bigger they might be able to eat a few of the medium sized ones up. A 40" hybrid (Musky x Pike) can eat a pretty large carp. They are steril so they will not over populate.
