(Northland's NewsCenter) -- The Minnesota Department of Natural Resources reports that a silver carp and bighead carp were caught in a seine net by commercial fishermen on March 1 out of the Mississippi River near Winona.
The silver carp that was caught weighed 8 pounds and represents the farthest upstream discovery to date.
"A silver carp discovery this far upstream is discouraging, but not surprising," said Time Schlagenhaft of the DNR's Mississippi River Team at Lake City. "This is further evidence that Asian carp continue to move upstream in the Mississippi River."
Populations of bighead or silver carp are not known in Minnesota, according to the DNR. However, individual Asian carp have been caught by commercial fishermen in recent years.
According to the DNR, between 2003 and 2009, six bighead carp were caught in the Mississippi River between Lake Pepin and the Iowa border.
Big head carp can weigh up to 110 pounds and silver carp up to 60 pounds. They are capable of consuming 5 to 20% of their own body weight each day. Scientists believe Asian carp could severely disrupt the aquatic ecosystems of Minnesota waters.
