Cool thanks for the info. Here's a thought. Yellow perch spawn before crappie, right? If one of the reasons crappie take over is because they spawn before other sunfishes and gain an advantage, would it make sense to stock heavy on the yellow perch to help take away that advantage from the crappie? Another thought was using hbg to help control crappie as soon as they spawn then letting the hsb take over once they get a little to big for the hbg. I believe Bill was talking about Adult hbg wiping out bass spawn in an earlier discussion. Would they do the same for crappie.
