Getting an over crowded LMB 12 ac back into balance is a big task as you probably know. Plan on an electroshocking every year or twice a year until you see decent progress toward your goals. I won't be cheap in time spent or money. Removing 240 to 360 lbs of bass from 12 ac will be a big challenge. Then you could be left with hook smart brood stock. Then will the growth potential of the brood stock be capable of growing more 10-12 lb LMB. Be prepared for a big project.
