Why Are Asian Carp a Problem?

Why are carp a problem? 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.

How did the Asian carp get to America and why are they a problem?

Asian carp were brought into the United States intentionally by humans to capitalize on the carps dietary preferences. Bighead, silver and grass carp were first introduced to control nuisance algae blooms and aquatic vegetation in aquaculture facilities, farm ponds and sewage lagoons.

What problems have been caused by Asian carp?

The first is a food problem. Asian carp don't eat other fish, but because of their voracious appetites (consuming up to a third of their body weight per day) they could easily out-compete native fish that rely on specific sources of food.
