I was thinking more of an "Old Forum Members'" tale, george.
I have only noticed very temporary effects. Bass feeding is off if I feed quickly following catching a LMB on a pellet. And when I had more CC, catching one on anything resulted in 9 out of 10 CC avoiding feeding for a couple of hours or more. OTOH, I have never noticed any decrease in feeding with BG wrt some being caught. Biggest effect was on GC; I had decreased GC pellet feeding for about a month after hooking 2 of 5 on Stubby Steve's in a two week period (but that was a good thing).
