AR-Tenner. have you and your bride considered Hybrid Black Crappie? Smallmouth Bass, Walleye, Hybrid Striped Bass and Yellow Perch could be good additions to your smaller forage, plus provide amazing tasting table fare.
Hybrid Crappie reproduce, but the offspring are inferior to the parents and are controllable by some predators.
Redear sunfish are a panfish that should be added to control snails, and the parasites snails host.
If your golden shiners establish well and have some cover, I doubt regular Black Crappie will control them, and if your Crappie pull off a couple boom spawns, the GSH will outgrow the stunted BCP that will be everywhere.
Actual carrying capacity in any pond is forever changing, but if it were static and could support a maximum 1000# of fish, it could be I, 1000# fish, 1000 one pounders, or 16,000 one ounce fish....every spawn, without balanced predation, you get more, yet smaller fish.
