The using of more BG (2500-3000) per acre @ 2in size has been found to increase the time period at which the LMB out eat the forage base from 18 - 24 mths to 36-48 mths in southern ponds. Keep in mind that new ponds approach carrying capacity in the south at about 2 yrs. So, keeping a strong forage base beyond the reaching of carrying capacity is important for fish size structure in your pond. Generalities, so recall, it depends on water quality and productivity.
