Probably the most important concept to keep in mind when adding additional forage to support/improve LMB growth and size is harvest of LMB. There are two parts to the equation - more forage and fewer predators.

For example it is not unheard of for the adding of more forage to result in more skinny LMB (absent harvest) not better conditioned LMB. Same for starting a feeding program - more skinny LMB over time rather than less.

It is not easy to guess correctly at how much more forage and what sizes are needed or to find those fish. I would rather be in the over forage - under predator situation and work toward balance than try it from the other direction (low forage - high predator).
