Guarding the Great Lakes

TRAVERSE CITY, Mich. — At least some Asian carp probably have found their way into the Great Lakes, but there's still time to stop the dreaded invaders from becoming established and unraveling food chains that support a $7 billion fishing industry and sensitive ecosystems, according to a scientific report released Thursday.

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.

"The most plausible explanation is still that there are some carp out there," Christopher Jerde of the University of Notre Dame, the lead author, told The Associated Press in a telephone interview.
