Got confirmation of what I expected. Ran into someone who fished the pond several times under the previous owner. He told him not to take any bass, but take all the bluegill he wanted. He would take 30-40 bluegill a day several days a week in the summer. No wonder my bass have a RW of .75. Continuing to keep everything under 14 inches until my RW improved. Will add bluegill and redear in the spring. Working on additional structure and improving the water quality also (testing kit in hand).
