In the St. Paul Pioneer Press this morning:
“Bighead and silver carp have been discovered in a portion of the Mississippi River above the Hastings dam, the farthest north they have been discovered in the river or its surrounding lakes.
Commercial fishermen contracted by the Minnesota Department of Natural Resources netted one each of the invasive species, including a 40-pound bighead and 20-pound silver carp.
The fish were caught near Cottage Grove on Thursday, in Pool 2 of the Mississippi, the DNR said. Pool 2 is the portion above the Hastings dam, extending to the Ford Dam in St. Paul, and includes the backwater lakes of Baldwin, River, Spring and Mooers, as well as the Grey Cloud slough.
Both fish were females that contained eggs, the DNR said.
The species are considered dangerous to the river’s ecosystem, because of their ability to grow up to 60 pounds, requiring large numbers of plankton and other fish to sustain themselves.
Bighead carp previously had not been found above the mouth of the St. Croix River near Prescott, Wis.; silver carp had never been detected north of a section of the Mississippi near Winona, Wis.
In a written statement, DNR regional fisheries manager Brad Parsons said the findings were “disappointing but not entirely unexpected,” noting that carp can migrate upstream during high-water conditions such as those that occurred this year.”
well this is truly sad and as mentioned, not really unexpected
