Thanks very much for your response. My goal is simply to have a healthy, well- balanced pond. I'm not interested in trophies. I suppose my primary interest would be in the bluegill, bass, and crappie. I continue to read about crappies overpopulating, but locally it seems that most pond owners have a difficult time getting and keeping them established. Are the numbers and types I added this fall ok, or should I increase or add something else in the spring? Would adding regular BG be counterproductive to the HBG? I'll have lots of structure for the FH's to spawn on, so hopefully I'll have a good population of them before adding the predators. Eventually, I plan to aerate and feed as well.
