I live on the shore of lake Erie and its noted to be a pretty good yellow perch fishery---our fish are 30-50 ft down so its impractical to fly rod for them---the standard issue bait is an emerald shiner and ive tied clousers and other imitations to put on a dropper so when a perch takes the real shiner it would move my fly and another perch might pick it up---i have never caught one that way---maybe my flies are crappy
