ABSTRACT. Monitoring the spread of Asian carp has been a priority since their introduction and particularly important in the last decade as efforts to prevent them from entering Lake Michigan gained momentum.  Monitoring movement using acoustic tags (manual tracking and stationary receivers) provided a wealth of information to understand Asian carp behavior.  The advent of satellite telemetry and real-time, satellite-linked GPS tags can complement current acoustic efforts by tracking multiple individuals at once without the man hour investment needed to accomplish the same goal using other technologies.  Seven Asian carp (two bighead carp and five silver carp) were tagged with real-time GPS transmitters in the Dresden Reach of the Upper Illinois River between August 3 and August 30, 2017.  The data is accessed through an end user interface and the initial trial indicates several trends. Six of the fish remained in the lower 6 km of the 24 km long reach. Five fish also spent time in the Kankakee River near its convergence with the Illinois River. Over a 24-hour period, one of the silver carp traveled approximately 15 km from the lower end of the reach to a hotspot identified through acoustic tracking.  A total of 173 useable points have been collected from the seven tags.  Real-time GPS tags could be a useful tool to identify real-time aggregations to inform contracted removal on the water, identify habitat use, spawning and feeding locations, and inform management efforts.
