Regulations to Reduce Potential for Introduction of Aquatic Invasive Species

The State of Alaska has regulations and laws to protect our native fish and wildlife. Alaska’s stringent transport laws reduce the potential for intentional introduction of invasive species. It is illegal to stock any type of fish into waters of the state without a permit, release unwanted pets into the wild, and use certain gear-types when fishing or hunting in the Alaska.

Editor’s Note: The following is a summary of regulations pertinent to invasive species excerpted from the official codes on file with the Lieutenant Governor. There may be errors or omissions that have not been identified and changes that have occurred after this publication.

The Department of Fish and Game is responsible for the management of fisheries, wildlife and habitats. State fisheries are managed by the Division of Sport Fish and the Division of Commercial Fisheries. The Division of Habitat implements the state’s authority for Fish Habitat and Special Areas, while management of wildlife is delegated to the Division of Wildlife Conservation. For more information on Alaska regulations visit the Regulations page or for full text of the Administrative Code online, go to the Alaska Administrative Code-Regulations or contact your local Department of Fish and Game office.

New Regulations

Beginning in 2021, regulations prohibit possession, import, propagation, transport, release, purchase, and/or sale of organisms listed as banned invasive species without a permit. Examples of the banned invasive species includes signal crayfish, red swamp crayfish, yellow perch, zebra mussels, quagga mussels, American bullfrogs, Asian carp, and New Zealand mudsnails.

Non-native species are categorized as banned invasive species if they are able to:

  • Survive and establish sustainable populations in Alaska;
  • Compete with native species for food, habitat, or resources;
  • Degrade habitat;
  • Transmit diseases;
  • Threaten the health of or a population of native species, or
  • Cause economic or environmental harm.

See Alaska regulation 5 AAC 41.075 for more detailed information and a complete list of banned invasive species or view our FAQ about banned invasive species.

  • BOG will remove a species from the Clean List if there is a preponderance of evidence that the species is capable of surviving in the wild in Alaska; causing genetic alteration of an indigenous species; causing significant reduction in the population of an indigenous species; transmitting a disease to an indigenous species; or otherwise presents a threat to the health or population of a species that is indigenous to Alaska.


  • It is unlawful for the owner or operator of a vessel, vehicle, aircraft, structure being translocated, or other means of conveyance to knowingly or unknowingly transport or harbor live Muridae rodents, or to enter this state, including by the waters of this state, while knowingly or unknowingly transporting or harboring live Muridae rodents.
