Bob Lusk says it takes 10lbs of forage to gain 1lb of bass. How much forage does it take for bass to keep from losing weight? Is this 10lb rule apply to all sizes of bass? For example, if a bass is 2 lbs does it take 10 more lbs to get to 3lbs and if a bass is 11lbs does it take 10 more lbs to get to 12lbs?
