I'm not qualified to guess where a bunch of 7 to 10 lb fish went. Like Cisco says, they may have gotten conditioned(educated). Try a 6 inch bluegill.

How is your forage base? I'm betting there are some gaps that are influencing growth to get the bass above 4 or 5 pounds.

How is your water quality? Is it fertile enough to support a huge forage base?

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.
