One of the biggest threats currently facing aquatic natural resources is the establishment of aquatic nuisance species. ANS are nonnative aquatic species that threaten the diversity or abundance of native species, the ecological stability of infested waters, or commercial, agricultural, aquaculture or recreational activities that depend on such waters, and cause negative economic or ecological impacts. In areas where they have become established, ANS have proven expensive to combat and difficult or impossible to control or eradicate. North Dakota currently has a limited number of ANS that threaten our waters and the activities that rely upon those waters. For more information, see our ANS page
To conserve our natural resources for the future, the North Dakota Game and Fish Department strives to prevent the introduction and spread of ANS into and within the state, as well as to minimize impacts of existing populations. Boaters, anglers, hunters and water enthusiasts such as yourself are paramount to detecting new ANS when they first enter the state or as they begin to establish populations. If you find any fish, plant or other animal that looks out of place, use the form below to report your finding. Even if it turns out not to be an ANS, the information you provide is extremely important.
Tips for what to do if you find a potential ANS
- Take pictures of the organism and where you found it. If possible, place the organism in a plastic bag and freeze.
- Record exactly where you found the organism and get a GPS location if possible.
- Take notes on the finding, including how you found the organism, whether you found it on shore, and details on the site (vegetation, water depth, sandy substrate, etc.)
- Look around to see if any similar organisms are around and if there are a lot or a few.
