Nonindigenous Aquatic Species

Aquatic Wildlife is threatened by some species of animals that are not native to our U.S. waters. These species, which scientists label as nonindigenous aquatic species, change or alter habitats, or homes, of native plants and animals. This can result in significant economic impacts and alter the natural balance within aquatic communities. In aquatic environments, these invasive species can be very harmful, or noxious, because the native species are not able to compete with the new species for food.  Habitats are also threatened and native animals may become prey, or food, for the nonindigenous species. Often these species have no natural enemies in their foreign habitats, and their numbers may increase rapidly. Scientists monitor these nonindigenous species and work to protect aquatic habitats.
