I have spoken with Robert Hrabik (currently working a revision of the Fishes of Missouri guidebook) and he basically stated that the rock bass in SW MO are a mess. There have been lots of bucket migrations and possibly a fair amount of hybridization. I have not counted scale rows though have been inclined to do so for other fish id work. With rock bass I have fished in the traditional locations for each of the three species and tended to avoid cross over areas.
Not yet Phil ! I'm working on it.
Here is a listing of the sunfish, i.e., Centrarchidae family, that I have caught so far. Except for the redbreast, pumpkinseed, shoal bass, redeye bass, and the Florida largemouth, all of these I have caught in Missouri or Arkansas.
