We had a river with them a couple years back, then they just vanished. They were great eating, a lot like gills, but more sweat, if that makes sense. I cooked them the same. Deep Fry, or my favorite, in a little foil tray on the grill with some butter and onions.
The thing with yellow bass is when you are cleaning them, but sure to cut out the red blood line. If you leave that in the fish will not taste good. If you cut that out when cleaning, then they taste like a gill.
I cleaned them up already. They made nice little fillets. They are for sure yellow bass. Clear Lake here in Iowa is full of them! I didn’t see a big blood line though…
