Do Asian carp affect native species?

Many studies show that bighead and silver carp substantially change ecosystems where they have been introduced. Studies around the world, including a USGS study in the Missouri River, found that zooplankton populations are dramatically reduced when Asian carp are abundant. In the presence of high densities of silver carp, large phytoplankton (plant plankton) species decline, but very small phytoplankton species, too small to be fed on by silver carp, usually become more abundant. The end result is water that appears very green but has little zooplankton. Native fish that eat zooplankton may be negatively affected by Asian carp if food resources are limited. Furthermore, since nearly all fish feed on zooplankton when they are very young, most species have the potential to be affected. There is also evidence of native planktivores being out-competed by Asian carp for food resources in the U.S. as well as around the world.
