Waymon, I originally stocked about 75% bluegill and 25% coppernose. A couple of years later, I never catch a coppernose. I assume they didn't make it or crossbred. I also have never caught any of the shellcrackers I stocked. Why? Beats me. I remember a comment by a State Biologist on the Mississippi Fishing Website saying that a Texas study indicated that Coppernose don't outgrow native bluegill. If so, why did I pay more for them? Why mess with them?
