I just don't see the point of not allowing tilapia to be stocked in a private pond. Its not like the tilapia could ever walk across land and get into another body of water from a pond/lake I would build.
All it takes is one hurricane and the 15" it could drop in rain and you'd be amazed at where fish from one private pond can end up! All those lovely Asian carp now screwing up the Mississippi River drainage all started out in a just a few private ponds, until heavy rains flooded them out...
However, GA is way too far north for tilapia to consistently survive winters, so other than them surviving in warm water refuges(power plant outflows, etc) I don't see a major issue. Even VA bans tilapia, so it isn't just GA.
