FYI..This past Sunday's PBS "Nature" had a show which showed this...the scientists studying the fish have determined that the react to a very slight electric current by jumping..that's how they study the fish population..they showed them hitting the switch, then the lake literaly exploded with these carp leaping into the air..check your local PBS station..they usually rerun it during the week..
Sounds like skeet shooting could be raised to another level.
Might even be fun.
