Snails - small, easy to transport
Vegetation - relatively easy to transport
Snakeheads - they'll be here with cockroaches after the nuclear strike
Hogs - more difficult but it's been done


I know people transfer stuff. Asian carp "could" be transported, but the likelihood of someone bringing them from Kentucky Lake (where they're most prolific) across the state to put into Chickamauga and the fish surviving, is maybe a brazillion to one. And they're not a big enough food source yet for that to even be something anyone would do. They're just not.

It's going to be interesting to see how they impact the Tombigbee after they get into it since they're in Pickwick. The carp pretty much wrecked the Yazoo River, or portions of it, over in Mississippi in short order by depleting food (plankton) sources the other normal fish need. That's going to happen on Wheeler, Guntersville, Nickajack and Chickamauga in the shallow flats, too, if the carp get a firm foothold like at Kentucky Lake.


Speaking of snails, WTH ever happened with all the snails down in the Eastern Shore ditches and canals? Did they ever get any kind of grip on those?
