We have not been targeting perch yet, but have brought in a few jumbo's the last several days. We have been finding schools off the deep edge's of the gravel and mud flats. They have been hitting bigger spoons tipped with minnow heads that we are using for walleyes...but I bet if a person were to use a perch setup with a smaller forage minnow spoon and a crappie minnow head or maggots that you could get into some decent perch action.
Deep edge or the bottom edge off of the gravel or mud. Let us know how you did. Good Luck.
