On Stieger Lake in Victoria, Minn. — the headwaters of Lake Minnetonka — four workers in hip waders spent Friday morning tossing nearly 2,000 pounds of common carp from nets to a boat to the back of a pickup truck. The fish have become a nuisance in some lakes because they’re so good at moving around and destroying the habitats of more desirable fish species.

Carp removal project kicks off at Lake Minnetonka headwaters 

The carp management plan is based on data from a three-year study by the University of Minnesota’s Aquatic Invasive Species Research Center. The researchers found an unprecedented number of common carp in the Six Mile Creek system, including Lake Minnetonka’s Halsted Bay. They also identified where the carp are spawning and determined their migration patterns. The findings helped shape a management strategy that includes removing adult carp, installing carp barriers, and aerating lakes to ensure the winter survival of bluegill sunfish (which feed on carp eggs).

But the common carp that’s already here is an invasive species, too, and an undesirable one at that. It destroys aquatic plants and stirs up sediment, degrading water quality. Researchers in the north metro area are learning more about these fish as they try to come up with new ways to manage them.
