Why are ANS such a big deal?

Aquatic nuisance species (ANS) can greatly degrade or ruin habitats and compete with native and/or desirable species for food and space. Not only can recreational fisheries suffer, but so can industries and communities that rely on lakes or rivers for their water supply. Once established, the cost of controlling ANS would far exceed the minimal costs required to keep from spreading it into or within North Dakota. See our current list of ANS infested waters. If precautions are taken and everyone is in compliance with regulations, the spread can be controlled.
