I guess my question would be, if they are native to the Yangtze River in China, how are they getting into inland ponds and waterways here in GA. A pond in Gwinnett County GA is not a place where the normal accidental methods of transplant occur, such as bilge pump water discharge, etc. So are these considered a good fish to eat? Are they a fish normally seen in pet shops. For someone to be intentionally planting them, they must have a need. Either disposing of an unwanted pet, or trying to cultivate something that may have been part of their diet somewhere else.
Something fishy is going on.
Probably brought in by birds from Florida. Birds walk in the water and the eggs stick to their feet and they fly off and spread them to other bodies of water.
