Scientists have published a paper defending their contention that DNA evidence shows Asian carp have gotten past an electric barrier designed to keep them out of the Great Lakes.
The paper is being released Wednesday by a journal called Conservation Letters. It describes how biologists with the University of Notre Dame and The Nature Conservancy gathered more than 1,000 samples from waterways near Chicago. Of those, 58 contained DNA from Asian carp and were taken beyond the barrier.
Sadly, now the argument is going to move from "What about the ships?" to "Oh, but they're already in the lake...no use closing the locks now."
