Yak, depending on your eventual goals, I would suggest adding about 300-500 adult BG in the 6" size range. I would suggest adding 25-50 pounds of Fathead minnows, ONLY to distract young bass from munching on as many BG offspring to help build your main forage base. 10-25 pounds of Golden Shiners would be a good forage fish for your HSB and LMB, if there is enough vegetation to let them establish. You may want to try removing some of the Grass Carp also...are the stripping nearly all vegetation except FA? Since the pond was drained and sterilized, was there anything even there for the Grass Carp to eat???
