Norm -- yes, I would mostly agree with you. There would be no harm and potential value in initially stocking the smallmouth bass, channel catfish, and walleyes in addition to the largemouth bass and bluegills. Bill Cody just agreed with you on the walleyes. My conservative nature causes me to want to wait on the pumpkinseed stockings.
Here's my thought process on punkies. TyW is already worried about an overabundance of small bluegills. If only a moderate density of largemouth bass develops in the pond, then I worry about the capability of the bass to control multiple panfish species. In a situation without crowded bass, I have seen that the more panfish species added, the greater the risk that the bass will not be able to control them. Now, I strongly suspect that TyW's pond will move toward crowded bass, but we can't be certain. I'd rather be sure that the largemouths are reproducing and heading toward high density before I add the pumpkinseeds. As you know, I still have this old-time, conservative background that just can't shake the fear of panfish getting out of control. :-)
Channel catfish should not be stocked at too high a density because there can be some competition between them and bluegills for aquatic invertebrates.
Bill -- Great thoughts. Many thanks for your time.
