  2. Native to: Eastern Russia and China • How they got there: They got to North America and Europe as food, part of pet trade, and sport fishing • Impact on environment and economy: The carp take over the food and habitat of native fish. They have been known to prey on the eggs of certain fish. • Methods of control: some special methods are holding special events. 1.The Asian carp NY

  3. Native to: Black, Caspian, Aral and Azov seas • How the got there: Zebra mussels were brought over in ballast water. • Impact on environment and economy: This species is a very aggressive fresh water species which will populate fast. This species will destroy whole entire plankton populations. They also clog up pipes which cost lots of money to fix • Methods of control: chemicals are used to kill the larva Zebra mussel ny

  4. Native to: Northern South America, Central America and Mexico • How the got there: Cane toads were brought over as a way to control crop pests. • Impact on environment and economy: The toad produces a natural toxin that predators don’t have a resistance so the toad will take out lots of plants and predators • Methods of control: Cane Toad

  5. Native to: Asia and Africa. • How the got there: It is thought that they arrived when aquarium owners didn’t want their exotic animals so they dumped them in local lakes • Impact on environment and economy: they threaten the native species of an environment. • Methods of control: they can be controlled by putting toxins in the water Northern Snakehead ny

  6. Native to: Atlantic ocean • How the got there: they got here through cannels and locks that were built from the great lakes to the ocean • Impact on environment and economy: it is thought that about 29 million dollars were lost at lake champion because people stopped fishing there • Methods of control: they are trying to add barriers to stop the migration of adult sea lamprey Sea lamprey Ny

  7. Native to: Ponto-Caspian region of Eastern Europe and Western Asia • How the got there: it is thought they can from international ballast water from tankers • Impact on environment and economy: it is thought that this invasive species is going to impact the food web in a bad way. • Methods of control: they clean, drain, and dry the water to rid of the water flea Spiny water flea

  8. Native to: fresh waters of eastern and southern Asia. • How the got there: no one knows how they got here but it most likely involves human activity, such as debris floating across the ocean is one theory. • Impact on environment and economy: this species can effect a very sensitive aquatic eco system and release a chemical that makes algae grow better • Methods of control: the use of bottom barriers has been used to stop the speard Asian clam ny

  9. Native to: western Pacific Ocean from Russia to Hong Kong and the Japanese archipelago • How the got there: it is theorized that adults or larvae were introduced by ballast water from international shipping. • Impact on environment and economy: it can hurt the populations of native fish and crabs • Methods of control: parasites will help control and potentially take this species out in a area Asian Shore Crab

  10. Native to: Black and Caspian Seas and the Sea of Azov • How the got there: it is thought they arrived from ballast water from a cargo ship the fish flourished in it’s new environment • Impact on environment and economy: the fish will take over spawning sites near the shore and aggressively attack any other fish that come near their site, this will slowly decrease the population of native species • Methods of control: one way to drain the water of your boat to stop the spread of eggs Round Gobyny

  11. Native to: Europe and parts of Asia. • How the got there: they were brought as pets and zoo animals until they escaped and lived in the wild • Impact on environment and economy: the swan poses a threat to vegetation and the animals that feed of the vegetation. • Methods of control: In many states, egg addling, culling, and euthanasia have been performed to control mute swan populations.
