While the adult carp prefer slow moving water, they look for high, fast moving water when laying eggs (spawning). They lay hundreds of thousands of eggs at a time, which means populations grow and spread quickly. Because of this, they can quickly out-compete native species, and put ecosystems in danger.
Carp are also thought to lower water quality, which can kill off sensitive organisms like native freshwater mussels.
Asian carp cause serious damage to the native fish populations in the lakes and rivers that they infest because they out-compete other fish (video, 1 min) for food and space. Carp are also thought to lower water quality, which can kill off sensitive organisms like native freshwater mussels.
The Asian carp populations increase rapidly because they are invading native fishes area. They invade native fish like salmon or catfish causing a slight decrease in there population.
