Good advise so far. Ponds are unique from inland lakes because the proper balance is so fragile. Friends of mine have been fishig four farm ponds in southern Georgia. They caught bass up to 9lb+. They hired a biologist who electroshocked the two best ponds. He interpolated the shock sample, 10-20% of the pond population, to make his recommendations. Add so many bluegills per acre and remove all small bass caught until the remaining bass caught look super healthy. Unfortunately after the bluegill fry were added southern Georgia went into a two year drought & decimated the big bass. One of the ponds was additionally drawn down to irrigate crops. Now they have to remove all stunted bass under 15 inches to help restore a healthy balance. On a side note I heard large crappie are big time predators of bass fry.
