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.
