It could be a pure GSF but I don't think so. . .
Totally agree. So an update. A couple of weekends ago I caught a few of them for bait (6 + inchers). It was big bait and I was after big fish as I am trying to catch a couple 25"+ CC I've been seeing in one pond. I had 8 left when I quit and released them. Now here's the rub.
I've caught and released maybe all of them since then. Last night, I think I caught seven of them ... though perhaps I might have caught a couple twice. They are thin and much easier to catch than the bluegill that are in the pond, a handful of which are large >10". YOY in this BOW achieved > 6" this year. I think the hybrids will be a good indicator as to when, if at all, someone comes through harvesting panfish on this BOW.
John, are you finding snails in them? I am. RESXGSF definitely eat them.
