I have fished the pond heavily and only caught 2 tiny stunted BG. I believe there are very few in there and the one's that are in there are starving to death with no minnows or anything to eat. I was hoping to just introduce good genetic BG from Overton's and let the LMB wipe out the old, stunted leftover BG.
What are you fishing with? To sample BG I would recomend no bigger than a #10 hook or similar size jig head with a pinch of worm or Gulp Alive waxies or some similar very tiny bait.
