Indiana DNR is offering a $100 reward for catching a black carp, a newer invasive speiceis and related to the Asian of course .
Two have been caught in the Ohio river, Indiana side. They feed on mussels many of which are already endangered.
The story is on Fox59.com (where I work).
I did a search for "Black Carp in Indiana" and found more links.
I would post links but I am not good at doing such.
