I'd love to catch a cooler full of perch, but don't know enough about them. I occasionally catch a handful, but usually there small. I kept four that were about 9 inches and return three more that were only five or six inches. Probably the most I've ever caught in one area. I caught one way up Limestone Creek a couple years ago that was almost 13 inches and weight about a pound. Wished I could find where the big ones hide, LOL.
