Ok guys this is not an easy topic. Keep in mind that no matter what you stock initially they will try to fill the pond with their kind and will do so in 18 mths +-. So in that period in his location the pond will reach carrying capacity. Everything else is about mgt of the existing stock. State the goals first then we can go over the how to. In anything like normal stocking #s the SMB and HSB will not control BG #s. If you used 3-5 inch BG to stock just before the first BG spawn they will not be eaten by the under 12 inch predators. They will spawn and a good % of the BG offspring will survive to age 1 and certain reproductive fitness. But some of the early first spawn BG will in turn spawn the first summer. By then the pond will be full of fish. The biggest predator of those BG yoy will be the adult BG not the HSB and SMB. There are way to many variables in play to get the number just right and that is where the goals come in to play. Do you want to shade toward to few BG and a descending time curve toward trophy BG or shade toward to many BG and a descending time curve toward trophy SMB/HSB. Harvest mgt and food supply will have to do all the rest toward the goal. Its a #s game over time where you can only slightly stack the deck one way or the other with the initial stocking. The info on HSB/SMB ponds with BG is sparse and specific pond factors like water quality , weather , food availability , trophic state of the pond will play large rolls.
