The Asian carp mentioned here is the common carp in our market. It is also the raw material for the famous dish sweet and sour carp.

Because there was no carp species in the Americas at the beginning, Americans believed that carp like to dig in the mud to find food, which would seriously damage the natural waters. If there are too many carp, they will dig up the mud in large numbers to find food. The mud can kill other fish from lack of oxygen. Moreover, Americans do not like to put carp with a strong earthy smell on the table, causing carp to multiply in large numbers. Just like there was no ragweed on our land in the first place, it was already too late to discover the harm of ragweed. Therefore, it is more appropriate to use the term invasion of alien species (organisms) to describe it.
