Anytime an invasive species gets into an environment where it is an invader the potential for horrendous consequences exists. See cane toad or rabbits in Australia for example. I would say the Asian Carp is on the same scale.
Causing what is called a “trophic cascade”. For example, when American settlers wiped out wolves in Yellowstone National Park, this caused an increase in herbivores, which in turn led to a decrease in plants, which then caused a loss of birds.
