Dreaded carp: Can they be stopped? 
By Josephine Marcotty US Source: Star Tribune 8/12/2011

DNA from the invasive silver carp has been found at 22 sites in the St. Croix River, a development that has deepened despair about the imminent arrival of the notorious leaping fish and doubts that state and federal officials can do anything to stop it.

The Minnesota Department of Natural Resources announced Thursday that 22 of 50 water samples taken between St. Croix Falls and Franconia tested positive for silver carp DNA. The samples did not test positive for the other three species of Asian carp that are believed to moving upriver from Illinois, and another 50 samples from the Mississippi River were negative.
 

The results are not conclusive evidence that the fish are living and breeding in the St. Croix -- none has been found in the river -- or that they are absent from the Mississippi, DNR officials said. The DNA could have come from dead carp, live carp someone dumped in the river or fish pellets used in hatcheries.

Still, it ratchets up the fear considerably, they said.

"This is disappointing news," said DNR Commissioner Tom Landwehr.
