The world record bluegill was caught in Ketona Lake, Alabama. That is the area where the CNBG and northern BG intergrade naturally. So which subspecies grows bigger? I am betting they are about the same with the edge going to the CNBG but not by much. In the north, northern BG have longer life spans and reach big sizes by growing slow and steady. In the south CNBG have shorter life spans and grow big by growing faster.
