Drill alot of holes, slow your jigging down, and fish first close to the bottom, then higher. If the water is clear and you locate a school, you should do well, up here in Maine, we've got white perch all over, and there is not all that much of a trick to catching them. We seem to have our best luck on pink and orange colors, like I said, with a slower jigging presentation then what we use for yellows....Good luck
