  1. Asian Carp Gabrielle Yovane

  2. Natural History • Eight different kinds of Asian Carp have been introduced outside where they originally derive from • They include • Grass carp • Common carp • Silver carp • Large-scale silver carp • Big head carp • Black carp • Common goldfish • Crucian carp • Mud carp • They’re fast-growing, aggressive, and adaptable fish

  3. Natural History cont. • For over 1,000 years the largescale silver carp has been cultivated in China for aquaculture • “Four Domesticated Fish” in China are what the grass, silver, bighead and black carp are known as • The Four Domesticated Fish • Most important freshwater fish species for food • Most important freshwater fish species for traditional Chinese medicine

  4. Native Location • Asian carp are native to both Eastern Europe, Western and Southeast Asia • Other than being called Asian Carp, they are sometimes referenced as Eurasian carp

  5. How they were brought to the United States • Were brought to the U.S. in the 1970’s • They were brought to live like vacuums meant to remove algae and suspended matter (plankton, fine plant debris and minerals) from ponds and bodies of water • Specifically to filter the pond water in fish farms in Arkansas • Flooding led them to escape and reproduce by the 1980’s • Have now been found in open waters of 40 states • Over 97% of the biomass in portions of the Illinois and Mississippi Rivers • Currently moving rapidly North towards the Great Lakes

  6. Effect on the Environment • They cause damage to the native fish populations in lakes and rivers that they infest because they out-compete other fish for food and space • They’re thought to lower water quality, which kill off organisms like freshwater mussels • Known for dominating entire streams and pushing out other native species • Great Lakes • Worried if they get to the Great Lakes it will affect the fishing industry by out-competing the fish that are important for the fishermen

  7. How they’re spread • Asian carp are known to jump out of the water at high speeds • Capable of jumping over barriers and low dams • Flooding can spread them because flooding connects bodies of water that aren’t usually connected

  8. Control and Prevention • Federal and state agencies are studying barrier technologies that would prevent further spread • The Mississippi National River and Recreation Area is working with other agencies to create an Action Plan • The Coon Rapids Dam (near the Mississippi river) is constructing a barrier to prevent the Asian Carp from moving up river
