When ONC caught that nice fat 3 lb one that pretty much told the story that someone dumped it and a mate or two in the pond. That's why it was fat from eating his BG that he had first stocked. The smaller ones were fat until the prey was eaten up. The bluegills are also growing to a point where only the parent bass can eat them(it was fat). The young basslings now are 9" or so and are running out of grub to sustain them

That's my take on the story
