BISMARCK, N.D. (AP) — North Dakota's Game and Fish Department is implementing two emergency rules aimed at preventing the spread of zebra mussels from the Red River. State officials last month confirmed young zebra mussels at several locations along the river, and workers discovered an adult zebra mussel at Fargo's water plant. The invasive species compete with native species, clog water intakes and can even sink docks and buoys with their weight. Game and Fish Aquatic Nuisance Species Coordinator Fred Ryckman says anglers may no longer transport live bait in water away from the Red River.
