ABSTRACT: Asian Carp are a highly invasive species introduced into the Mississippi River System in the mid 1970?s and now, due to expanding populations, are a pervasive threat to invading the Great Lakes. The Dresden Island, Marseilles, and Starved Rock Asian Carp populations in the upper Illinois River (leading edge) pose the greatest risk to the Great Lakes and therefore understanding their habitat use and behavior in this region are important for removal efforts to limit further expansion. Therefore, the objectives of our study were to use acoustic telemetry to determine habitat preferences and connectivity, and areas of concentration of silver carp, bighead carp, and grass carp at this leading edge of the invasion. We tracked the three Asian carp species from early March until November 2018 using a mobile Vemco VR-100 receiver at pre-defined grid points (0.54 km apart) within the three pools. Ninety-two tagged Asian carp have been detected (53 in Dresden Island Pool, 14 in Marseilles Pool, and 31 in Starved Rock Pool). Data from this study will be used to identify seasonal habitats of Asian carp to increase the efficiency of contracted harvest of potential Great Lake's Asian carp propagules. Continued research will result in a better understanding of the factors influencing Asian carp habitat use and connectivity to help predict these behaviors and target removal efforts.
