Description

The Asian carp are an invasive species that was originally introduced to the United States in the 1970’s to help aquaculture and wastewater treatment facilities keep retention ponds clean. Flooding caused these fish to be washed into the Missouri and Illinois river systems and migrate throughout the Mississippi River. These fish can grow between 80 and 100 pounds and consume up to 40% of their body weight everyday in plankton. Specific treatment methods are being used to limit the expansion of the Asian carp population. A barrier that limits the fish from passing through to the Great Lakes has been implemented, as well as an electric barrier to prevent the fish from passing through.

Mathematical modeling and simulation of the spatial dynamics of this invasive species were used to better understand the rate at which this particular group of carp is expanding and to see the success of techniques used to slow their expansion. Through this mathematical modeling process, we experimented to predict the invasive species populations before they are introduced to new areas as well as after they have been introduced. We also mathematically analyzed this spatial dynamics model of the Asian carp fish population and the effectiveness of the treatments on slowing their growth.
