BISMARCK, N.D. (AP) – North Dakota wildlife officials say zebra mussels are still present in the Red River.

The nuisance species was first detected in the Red about a year ago between Wahpeton and neighboring Breckenridge, Minn. The North Dakota Game and Fish Department says young mussels were found recently in the same vicinity.

Zebra mussels compete with native species, clog water intakes and sink docks and buoys with their weight. Biologists believe the mussels in the Red River originated from Pelican Lake in Minnesota, which has adult zebra mussels.

Adults have not yet been found in the Red River or anywhere else in North Dakota.
