Sorry guys but I think y'all are way overreacting. I know the risk with crappie and have made that known to every pondowner I consult. It may be years b/f they start to "takeover". WIll all three survive, did you happen to get both sexes, wIll they find each other in a 3 acre pond? Sure try to fish for them, and take out if you catch one, but paying money to shock them out, is ridiculous (This coming from a guy who makes his living shocking ponds).
