I think one of those links above has a comment from Mr. Lusk saying that one of the Blues had a 3# LMB in it's gut. From my observations on what Gizzards do in a BOW, I don't think I'd stock them until the Blues were of a size that they could eat a 12"-14" gizzard.

The DNR stocked Blues in the local lake quite a number of years ago and IIRC, the last one that I remember being caught was about 20 years ago on a crankbait while fishing for LMB.
