GRAND FORKS, N.D. (AP) — Staff members from the U.S. Geological Survey have found three adult zebra mussels in the Red River in Grand Forks.

North Dakota Game and Fish Department aquatic nuisance species coordinator Fred Ryckman says the mussels were discovered last week on Red River sampling equipment at Sorlie Bridge. They attached to an aluminum pipe approximately three feet below the surface of the water.

Ryckman says the discovery was not a surprise, as one zebra mussel adult was found in Fargo earlier this summer. He says many veligers were found along the entire length of the Red River.

Game and Fish officials are reminding local entities and water recreationists to thoroughly check for new aquatic nuisance species infestations when pulling and storing fishing piers, boat docks and lifts prior to ice up.
