Silver carp
It is established in the Black River in Louisiana and probably the Mississippi River in Illinois and Missouri.  Several months ago I saw a story on the news where, in the Mississippi River in Missouri, Asian carp were jumping out of the water like flying fish and landing in fishermans’ boats.  One commercial fisherman said 26 carp landed in his boat in an eight hour period.  The media saw it as some strange phenomenon, but I believe it is typical, especially of silver carp.  People were actually being injured by these flying fish.
