Billy,
I'd think you should consider gizzards next growing season. They are actually a preferred food for HSB. I've had the gizzards in a HSB pond for a year now and have seen no problems with large gizzards....although that could still develop as a problem, I suppose. The research I've done shows that HSB love gizzards....possibly because they are also an open water fish just like the HSB. I see regular explosions of HSB on gizzards.
