Adult 5"-7" bluegill work very well when adding to an existing population of LMB that are in your size range. We had a forage issue with one of our ponds (1.6 acres) and the recommendation was to add 400 adult BG. We had an existing population of BG but not enough. It has worked out well. If you do a little research, it seems the recommended number of adult BG to add would generally fall in the 400 per surface acre area. BM61.
