Perch

While Port Byron, Illinois isn't known for saltwater or brackish environments, anglers can still find perch in the local freshwater areas influenced by the Mississippi River. Focus on the backwaters, sloughs, and calmer areas off the main channel. Perch fishing here is best in the spring and fall when the water temperatures are moderate. During these times, perch move into shallower areas to feed and spawn. Look for areas with submerged vegetation or rocky structures, as these provide cover and attract baitfish. A good local tip is to access the river from the Port Byron State Park boat ramp. Be mindful of the current, which can be strong, and adjust your presentation accordingly. Use small jigs tipped with live bait like minnows or worms. The perch in this area tend to be smaller, but what they lack in size, they make up for in numbers. Pay attention to water clarity; if it's murky, use brighter colored lures to attract their attention.
