Cecil, I was doing some research and came across your answer... Arizona does differentiate between bluegill and hybrids.

The state record bluegill is as posted above 3 lb. 15.68 oz. 15.75 in.

The state record hybrid was 2 lb. 2.22 oz. 12.5 in.

Other interesting sunfish records from AZ:
green sunfish, 1 lb. 9 oz. 11.0 in.
redear sunfish, 3 lb. 9.0 oz. 14.5 in.
warmouth, 12.0 oz. 10.0 in.
