Pond Boss Forums Thread Like Summary - What do I have here?

I dropped traps in the cow pond yesterday evening. The fine mesh Z trap was loaded with these little guys when I checked it this morning.
All of them were in the 1/2"-3/4" size range. There were 35-40 of them in the trap. I didn't try to dump them out, just put it back in the water.
When I got home from work today there was one left, along with ten or so BG in the 3"-5" range. The one pictured is ~3/4" and was the only
one still in the cage.

Is it a BG or RES from a late in '21 spawn, or is it a YP from this spring, or is the picture too blurry to tell. I couldn't get a better focus with my
cell phone cam from 3" away.

Note the "alamy" photo has a LMB on top and yellow perch below.

I'm willing to put money on it, that's how sure I am... :-))
