We developed a spatially-explicit, bioenergetics-based model of Asian carp individuals IBM to predict the likelihood of AC establishment and impact on Reproduction has not been documented in waters upstream of Marseilles Lock and Dam. DNA is extracted from the water samples and identified using genetic markers that are unique to bighead and silver carp. For more information on eDNA testing visit http: Sharon Gross, Robert Reed and Cynthia Kolar discuss issues related to invasive species and explain innovative methods used to help detect and control these invaders.

Loss of these recreational activities will likely have an influence on local economies. They consume plankton—algae and other microscopic organisms—stripping the food web of the key source of food for small and big fish.
