The pics are great..what about anatomical markings? or descriptive characteristics? I have CNBG purchased in Texas...

Actually, I'm glad you brought this up. I consider ewest to be the most "up-to-date" on CNBG characteristics. I'm hoping he'll link us up, then I can link this thread to bigbluegill.com

Bruce I credit Todd and George with a lot of this info.

I am glad to help bigbluegill.com . I go there and look and post but am not sure what I should do to help with the links.

What would really be helpful to bigbluegill.com would be to have a single good photo of both a female and male CNBG, with a brief description of what characteristics would help one tell that it is indeed a coppernose.

The only ones I can remember are the copper band (male only??) and the whitish fin bordering.

IIRC spine count on the dorsal is different from BG to CNBG, too.

Edit: Nope, soft rays on the Anal fin. See below.

Lets start here and when complete after comments you can paste it BB.com.

Three sources on CNBG traits/ morphology.

Coppernose bluegill have been around for a long time. They are only one of three recognized subspecies of bluegill (lepomis macrochirus). Coppernose (lepomis macrochirus purpurescens) is native to Peninsular of Florida. Coppernose bluegill have 12 soft rays on their anal fin as opposed to 11 soft rays found on the regular bluegill. Coppernose have fewer but wider vertical bars on their sides than do regular (common or native ) bluegill. Coppernose also have orange margins to their fins. Male coppernose has a broad copper band above the eye or forehead and are prominent during spawning season. Reproduction of the Coppernose is about the same as with most all bluegill.

The Coppernose bluegill is known for its colorful markings. The fins of the coppernose have a reddish orange fringe outline with a pencil thin white border. The vertical bars on the sides are more distinct and broader especially in the young. The distinct copper band across the head which is brilliant on the male is the reason for the common name "coppernose".

THE COPPERNOSE BLUEGILL (CNBG) IS ALSO A FLORIDA STRAIN. IT IS EASILY DISTINGUISHED FROM THE NORTHERN BLUEGILL BY ITS COLORATION AND MARKINGS. THE FINS OF THE CNBG ARE REDDISH-ORANGE WITH A THIN WHITE MARGIN. THE TYPICAL VERTICAL BAR PATTERN OF THE BLUEGILL IS PRONOUNCED IN THE COPPERNOSE, AND VERY DISTINCTIVE. ADULT MALES HAVE A BROAD COPPER BAND ACROSS THE HEAD THAT IS THE TRADEMARK OF THE STRAIN

i'll throw these pics in the mix, (same fish) caught in southern CA, probably a male but not sure, definitely a CNBG......

one shows the fin margins really nicely, the other the copper nose bar...

Excellent photos. I've already transferred them to http://www.bigbluegill.com

Anything on actual water temp tolerances?

I will locate the temp info - very similar to Fla LMB geographic range but IIRC the CNBG is a little more cold tolerant.

I assume the copper band on the forehead is more pronounced or visible during spawning season. Does anyone know if the thin white margin on the fins is more pronounced during spawning season?.

Are the yellow belly markings particular to the female?
