Yes, it's possible to overstock coppernose and any other fish. However, I believe you have seriously understocked your forage base. You haven't said how the coppernoses are doing but I assume you have reason for concern based on your observations. Nor have you said anything about the timing involved in the introduction of the various species. Timing can be critical.

The following assumes that you are like me and not overly encumbered by patience when it comes to stocking bass.

My personal thought is that you ought to add about 1,000 small coppernoses or about 300 larger breeders plus consider 5 to 10 pounds of breeder size tilapia to take some of the pressure off them until they can get really well established. If you want FAT bass, then they need a really good forage base and maybe culling to control their numbers. The "average" one acre Texas pond often winds up being bass heavy/forage light due to the catch and release mantra. You may have more bass than you think and it's easy to wind up loving our bass to death.

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.
