Dan, is probably referring to the Big Head Carp which supposedly jump 10+feet out of the water and are as large as 70-80 lbs. These would be to large for even Q - The Carp Stalker
They have been known to have hurt people when landing on them.
They are migrating up the Mississippi river to the Illinois River to the Illinois Ship Canal which connects into Lake Michigan and are a great threat to the great lakes fishery.
They are putting in electric barriers to stop them, hope they work.
Dan probably has higher priority stories now with the Irag situation heating up or perhaps the Springsteen or Mcartney tour etc (They are in Chicago the next two nights).
I posted an article on this a while back, do a search for it and it should come up, try "Big Head Carp"
