I have a pond I recently inherited. It is the size of a football field. Has a rocky bottom, lots of twists and turns, a few old trees hanging in the middle. As well as bushes with no leaves all around the pond interior. Water is fairly clear. I fished the pond. Caught a lot of bass. I noticed two things... one, the smaller bass <1# look healthy, maybe a little skinny. 2, the larger bass >2# have a skinny belly and big head. I caught a 4lber that had the head of a 8# fish. My question is, how do I make my larger LMB fatter? The pond can not be reached by auto or 4wheeler.
