I posted about these last year in hopes of finding someone who had good info on them. I caught a little over 20 of them in one location last year while fishing for bluegills. I've been watching this year in hopes that they return. I believe the higher the water, the better for the yellow perch. As was said on an above post, they like weeds. When I was catching them they were in weeds and preferred those type of spots. After the water level started back down I couldn't find any. I also found that they liked feeding on the bottom mostly instead of with using bobbers. They are the best eating fish I've ever had. They are flaky like a walleye. I used worms for catching them, but small minnows might work as well, I'm not sure. I sure hope they show up again this year, because if they do I will be leaving the white bass alone, lol. Oh and I also keep the little tiny ones to, lol.
