The goal of the pond is to raise large bluegill. I'd like to be able to raise as many large fish as possible. Most of the fish I remove are around 3-5 inches. Harvesting bluegills is the main means of controlling the population. I harvest some to eat and also transplant some to other ponds. It's a small enough pond that I feel I can keep them in check just by harvesting them.
With the amount of larger fish in the pond I'm also guessing that a lot bluegill fry are eaten.
