Provides basic information about common carp and invasive Asian carp species. The newest invaders, bighead carp, black carp, grass carp, and silver carp that originated from Asia are collectively know as "Asian carp." These carp species are causing issues in the Mississippi river and surrounding waters. Asian carp are fast growing and prolific feeders that out-compete native. Asian carp have been known to dominate entire streams (video, 45 sec), effectively pushing out the native species. Silver carp are known to jump out of the water at high speeds, which can injure boaters and damage boating equipment. So, what does a school of jumping silver carp look like?

Introduced Asian carp in North America pose a major threat to the ecology, environment, economy, and way of life in the Upper Midwest and Great Lakes region of the United States and Canada. Asian carp are a group of fish species, which include several known to be invasive, and represent the most urgent potential danger to the ecology of the Great Lakes. The Common Carp's Introduction into North America Arriving in the United States during the mid-1800s, increasing waves of immigrants could scarcely believe that this vast new land had no carp - it had been a cultivated food source, garden element, and symbol of strength and courage in Asia for over 4,000 years, and similarly esteemed in Europe for nearly 2,000!
Asian carp are in direct competition with native aquatic species for food and habitat. Their rapid population increase is disrupting the ecology and food web of the large rivers of the Midwest. In areas where Asian carp are abundant, they have harmed native fish communities and interfered with commercial and recreational fishing.
