Well not being native to GA still doesn't preclude them from being there. They aren't native to Maryland and we just found new records last week, they aren't native to Europe and they are EVERYWHERE. If theyve been aquacultured in Georgia then its highly likely theyve found there way into streams, not counting bait buckets and pet trades (I heard of someone selling one for 8 bucks because it was a blue form!). If you think you have a P. clarkii and you can find a larger specimen, flip it over and look for it's gonopods (reproductive parts in males). They are the second set of swimmerts and are modified in males, therefore used in identification. In all Procambarus they come to a large 90ish degree angle that looks alot like a pipe wrench, especially in P. clarkii. The rostrum (head segment) of a Procambarus typically come to a single point. I'm drawing a blank about what the areola looks like on the carapace (segment behind the rostrum), I think it is very narrow though. If you do have them then well I'm sorry theyve probably displaced to some extent your native crayfish. Georgia has MANY species of native crayfish, so there are/were likely other species native to your area. Personally (my two cents) I wouldn't breed them since they are such a destructive invasive/non-native on native crayfish communities and benthic communities as a whole; what will become of the offspring if you do breed them? If anything, find yourself, or I can scan you some images from a key so you can positively ID what you have. If it's P. clarkii, collect all you can (while staying within your states regulations of course) and cook them up.
