I appreciate the replies. I mostly fly fish but my friends all use other artificials and the lack of catchability seems to transfer to all. Stubby Steves has worked in the past but now does not work. I made a cork fly that replicates fish food and use a small #12 black hook, but BG, HSB, and LMB now turn away. My pond has large population of Threadfin shad but it is rare that you see any surface feeding. These predators seem to be prefer the fish food!

I found a Post by Bill Cody from 2013 and he stated that he cut his feeders off for 2 months to encourage his HSB to eat over abundant BG and indicated that HSB were also reluctant to strike artificials while running feeders. I will turn off feeders for several weeks to see if the fish become more aggressive.
