In the 0.34 acre pond I have been experimenting with for some time now, the only predators I have in it are HSB, albino CC and a handful of female only SMB and one lone LMB. I also have RES and RBS in it. I am looking at adding a couple dozen all female crappies to see how much they affect the forage fish population. If it isn't excessive, I will probably add 20 or so all female crappies each spring when they are easy to sex. I have been building the forage fish population in this pond for 5 years with several different species though, so the forage fish diversity is very high for such a small pond.

When the LMB hits 14", it'll be removed. When the CC hit 20" they will be removed. Only the SMB, HSB and crappies will be allowed to grow to maximum size.
