Invading species are introduced to the Great Lakes through foreign shipping, aquarium & water garden trades, live fish trade and aquaculture. These species can be further spread to Ontario's inland waters through recreational activities such as boating and angling. In 1992 the Ontario Federation of Anglers and Hunters, in partnership with the Ontario Ministry of Natural Resources, established The Invading Species Awareness Program.

Nonindigenous Aquatic Species (NAS) information resource for the United States Geological Survey. Located at the Center for Aquatic Resource Studies, this site has been established as a central repository for accurate and spatially referenced biogeographic accounts of nonindigenous aquatic species. The program provides scientific reports, online/realtime queries, spatial data sets, regional contact lists, and general information. The data is made available for use by biologists, interagency groups, and the general public. The geographical coverage is the United States.

The purpose of these pages is to provide an information network for the various interests involved with management of aquatic nuisance species as well as to educate the public. The Western Regional Panel on Aquatic Nuisance Species was formed in 1997 to help limit the introduction, spread and impacts of aquatic nuisance species into the Western Region of North America. This panel of public and private entities was formed by a provision in the National Invasive Species Act of 1996 (P.L. 101-636), the amendment to the 1990 Act.

Division of State Lands Home Page. The Bureau of Invasive Plant Management (bureau) is the lead agency in Florida responsible for coordinating and funding two statewide programs controlling invasive aquatic and upland plants on public conservation lands and waterways throughout the state. Florida's aquatic plant management program is one of the oldest invasive species removal programs with its beginnings dating back to the late 1800s.

Invasive Species: any species of insects, animals, plants and pathogens, including its seeds, eggs, spores, or other biological material capable of propagating that species, that is not native to that ecosystem; and whose introduction does or is likely to cause economic or environmental harm or harm to human health

The Global Programme of Action for the Protection of the Marine Environment from Land-based Activities (GPA) aims at preventing the degradation of the marine environment from land-based activities by facilitating the duty of States to preserve and protect.

The International Conference on Aquatic Invasive Species is widely considered the most comprehensive international forum for the review of accumulated scientific knowledge, presentation of the latest field and laboratory research, introduction of new technological developments for species control and mitigation, discussion of policy and legislation to prevent new introductions, ballast water and other shipping-related issues, and public education and outreach initiatives to raise awareness about aquatic invasive species.

Exotic aquatic invaders are impacting all our shores. Invasive species, including Zebra mussel and green crab, have had serious ecological and socioeconomic impacts from the Great Lakes to the Gulf of Mexico, and from the Atlantic to Pacific oceans - and rivers and lakes in between. For example, the Atlantic coast is also impacted by exotic species such as the green crab, Carcinus maenas, and purple loosestrife, Lythrum salicaria. Important ecosystems such as the Chesapeake Bay have been invaded by exotic plants and animals that have been introduced in ballast water dumped by foreign ships.
