By stocking FHM along with your fingerling panfish, you may take a slight bit of pressure off of them... Bass will feed on the easiest to prey on item. FHM are fusiform and spineless, crappies and sunnies are more rounded and spiny... However, depending on the density of your bass population, they may quickly work through all the FHM and be right to eating your fingerling panfish... Stock smaller numbers of the crappie and sunfish, but stock larger ones. In the end you will get more to survive. Try to stock sunfish that are at least larger than 1/3 of the vast majority of your LMB.
