Perch are caught to be eaten. Study their habits, learn what they bite on and the equipment to be used. If I were just starting to angle for perch before the water warms to 40 degrees, I would look on the outside of a weedline in about 10 to 20 feet of water. Another trick is to watch the sky for swooping shorebirds feeding over the water. Below are schools of perch feeding on shad or other baitfish. Perch heaven.
