I am personally a fan of stocking pure forage fish as in FHM, tshad, GSH in the spring, BG, RES in the fall and then the predators the following spring. It gives the pure forage fish a full spawning season to make lots of babies before even BG or RES could prey on their young. The BG and RES going in the pond in the fall give them a head start on the predators, but not too far a head start.
