Bass shape good key to fishing a new lake

[CCbass]

This came to me during reading some studies while in school for wildlife biology but never came to life until later. I fished two lakes only about 10 miles apart, one had short stocky fish (they called them footballs) the other had longer proportional fish. For the same weight a fish was always a few inches longer in the longer fish lake. The study said short stocky fish feed on bait that don't move much, crawdads, bluegill, compared to say shad, trout, minnows. Fact is darker colors were the norm on the short lake, brighter colors on the longer lake, by my history and most you ask. This could be a great indicator on a new lake, if you catch more fish that are stocky (Footballs) compared to long and proprotional fish. By the way the longer lake is known as a great swimbait lake, the other not so much.
