I would agree that most are CNBG.
Maybe #1 and #9 RES.
I know that I have over 1,000 of these that live under my dock. It took about four days beginning in May for them to take to the Purina Gamefish Chow. I feed them every evening by hand, but apparently not enough. Some are still on the skinny side.

It is a real blast to see a 4-5 pound largemouth slam one while the frenzy is on.
