"Carp are a family of fish native to Europe and Asia. Common carp (#CyprinusCarpio) has been in the United States for over 100 years. The common carp is considered a nuisance fish or a pest fish. See Species Profile: Common Carp (Nonindigenous Aquatic species Database) for more information.
"The newest invaders, #BigheadCarp,#BlackCarp, #GrassCarp, and #SilverCarp that originated from Asia are collectively known as invasive carp or #AsianCarp. These invasive carp species are causing issues in the #MississippiRiver and surrounding waters. Invasive carp are fast-growing and prolific feeders that out-compete native fish and leave a trail of environmental destruction in their wake.
"The four types of invasive carp currently found in the U.S. were imported into the country for use in #aquaculture #ponds. Through flooding and accidental releases, black, grass, bighead and silver carps found their way into the Mississippi River system. The Mississippi River system is like a giant freshwater highway that has given invasive carp species access to many of the country’s rivers and streams."
