I would remove all of the CC's. They compete too much with the bass that you want to improve.

On culling: The rule of thumb is to remove all bass under 14 inches after the 2nd year.

Regarding the larger fish: You have to worry about the pond biomass of living creatures. Too many can cause a dissolved oxygen crash. The "average" closely managed pond can usually carry about 100 pounds of predators per acre. That may be a little bit ambitious. Remember that you need the larger BG for spawning but they are also part of the predator base. However, as a Northern pond, you also badly need LMB to control the BG spawning numbers. The LMB needs 10 pounds of forage fish to gain one pound and needs that forage to be 1/4 to 1/3 it's body size.

It's a balancing act and every pond is unique.

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.
