My recipe for the pond, at this time, would be 10 pounds of fathead minnows, another 1,400 BG and 100 to 200 redears. At this time, without bigger fish, your forage fish shouldn't experience a lot of predation. However, when the bass grow and spawn, they can and generally do over eat the food supply. The redears are not absolutely necessary.
You have this small window of time to do it right before the bass grow enough to wipe out the forage base.
BTW, in pond management, initial stocking is the cheapest thing but most critical thing you will do.
After the 2nd year, remove any bass that is 13 inches or less. Catch and release and too small to keep generally ruin private ponds. Bass are eating and spawning machines.
