UPDATE: Biologists search Sturgeon Bay for Asian carp

UPDATED Wednesday, November 13, 2013 --- 9:37 a.m.

STURGEON BAY, Wis. (AP) -- Biologists are back on the waters of Sturgeon Bay, looking for evidence of the invasive Asian carp.

A team of three biologists took water samples from the upper half of Sturgeon Bay to Green Bay on Tuesday. Wednesday, the team plans to take samples from the southern and eastern portions of the bay. WLUK-TV reports researchers will take a total of 150 water samples.

Asian carp have infested the Illinois River all the way to Chicago. Scientists fear if they reach the Great Lakes, they could threaten native fish species and harm a fishing industry valued at $7 billion.

Earlier this month, scientists said a water sample from Lake Michigan's Sturgeon Bay tested positive for Asian carp DNA, although it's unknown whether the genetic material came from a live fish.

MILWAUKEE (AP) -- The Wisconsin Department of Natural Resources says Asian carp DNA has turned up in Wisconsin's Lake Michigan waters for the first time.

The single positive water sample for the jumping silver carp was taken May 31 in Sturgeon Bay near Door County's Potawatomi State Park.

The sampling was part of a Lake Michigan-wide survey looking for evidence of Eurasian ruffe, a different type of invasive fish species.

The water sample was not screened for the presence of Asian carp DNA until this fall. DNR fishery director Mike Staggs says the agency did not get word of the positive result until last week.

The Milwaukee Journal Sentinel reports DNR officials plan to go back to the Sturgeon Bay area to do more sampling next week.
