The Minnesota Department of Natural Resources (DNR) has confirmed the capture of a silver carp below the Lake Bella dam in the Ocheyedan River, about 100 yards from the Iowa border in southwestern Minnesota’s Nobles County. DNR fisheries staff caught the invasive carp while following up on a reported silver carp sighting.
The Ocheyedan River connects to the Little Sioux and Missouri rivers in Iowa, where silver carp have previously been confirmed.
“While this is the first silver carp capture in southwestern Minnesota, it is not entirely unexpected,” said DNR invasive fish coordinator Nick Frohnauer. “High water this year likely aided the fish in getting this far upstream. Fortunately, the Lake Bella dam prevents invasive carp from swimming further upstream.”
The silver carp captured in Minnesota waters was a 28.8 inch male weighing 9.4 pounds.
Frohnauer noted that while the DNR continues to be very concerned about the potential impacts of invasive carp in Minnesota waters, individual adult fish captures do not indicate reproduction or an established population of invasive carp.
Invasive carp have been progressing upstream since escaping into the lower Mississippi River in the 1970s. These large fish compete with native species and pose a threat to rivers and lakes. No breeding populations have been detected in Minnesota waters.
The DNR invasive species program has built partnerships with state and federal agencies, conservation groups, university researchers and commercial businesses to prevent the spread of invasive carp. The 2015 closure of the Mississippi River lock at Upper St. Anthony Falls in Minneapolis was a major accomplishment in establishing a barrier to protect the Mississippi River and its tributaries above the Twin Cities.
The DNR is actively engaged with invasive carp prevention efforts in southwestern Minnesota. DNR fisheries proactively surveyed the Missouri River watershed in Minnesota to identify locations to prevent expansion of invasive carp populations in southwestern Minnesota.
The DNR completed eight projects that limit expansion and protect valuable aquatic resources.
Invasive carp captures must be reported to the DNR immediately. Call (651) 587-2781 or e-mail firstname.lastname@example.org . Take a photo and transport the carp to the nearest DNR fisheries office or arrange for it to be picked up by a DNR official.
