The heaviest largemouth bass sampled by us was just over 10 pounds.

The longest largemouth bass was 59 centimeters or 23.2"

The oldest fish was 15-16 years old. When fish get that old it becomes very difficult to be confident by aging a fish with scales only. More confidence can be obtained by aging a fish from otoliths, an inner ear bone, which is extracted cut in half and polished. Once this is done the bone is examined under a microscope and a very accurate age is obtained. We do this very rarely since it necessitates killing the fish, which we don't do lightly.
