Asian Carp a very invasive form of fish. Asian carp are fast-growing, aggressive and adaptable fish that are outcompeting native fish species for food and habitat in much of the mid-section of the United States. Asian carp were introduced into Southern fish farm ponds in the 1970s and quickly spread across the United States. They are now on the verge of invading the Great Lakes. Asian carp cause serious damage to the native fish populations in the lakes and rivers that they infest because they out-compete other fish for food and space.
