SOUTH BEND, Ind., April 4 (UPI) -- Asian carp DNA is not widespread in the Great Lakes basin, despite fears the invasive species could eventually proliferate in those waters, researchers say.
Written by experts who pioneered use of genetic data to search for the aggressive fish, the paper disagrees with government scientists who say many of the positive Asian carp DNA hits recorded in or near the lakes in recent years could have come from other sources, such as excrement from birds that fed on carp in distant rivers.

Researchers studying water samples from the Mississippi and St. Croix rivers for fragments of Asian carp DNA say they found little evidence of bighead and silver carp in Minnesota.
