Duluth, MN - (The Northland's News Center) - Water samples from the St. Croix River have tested positive for genetic material from silver carp, suggesting the invasive, leaping Asian species may be present in the river as far north as the dam at St. Croix Falls, according to the Minnesota Department of Natural Resources.
So far the results do not provide any information on the number or the size of the fish present in the river, or whether they are breeding.
No silver carp have been caught in the St. Croix River, either by commercial fishing operators or by anglers.
In order to combat the issue, the DNR will soon contract with commercial fishing operations to begin using nets and boats, outfitted with electric shocking capabilities in order to capture live silver carp.
The DNR will use a bubble or sonic barrier at the mouth of the St. Croix River at Prescott, Wisconsin, creating a barrier that would help to keep additional carp out of the river.
DNR operations could start as early as next week. commercial netting operations are expected to start by the end of August.
