Understanding the timing and drivers of migration can be beneficial for improving efficiency of response efforts aimed at reducing invasive species density or limiting risk of spread to other systems. Efforts by management agencies to remove grass carp (Ctenopharyngodon idella), an invasive species to the Laurentian Great Lakes, have been ongoing in select Lake Erie tributaries since 2018. To further aid control efforts, a seasonal, non-physical barrier has been proposed downstream of a known spawning location near Brady’s Island in the Sandusky River, OH to limit recruitment. However, knowledge of external grass carp migratory cues/timing and the potential effects the barrier might impose on native fish [e.g., walleye (Sander vitreus)] movements is limited. We used acoustic telemetry detection data from tagged grass carp (n=29) and walleye (n=84) to address three objectives: 1) quantify interannual variation of grass carp migration timing to Brady’s Island (BI), 2) assess overlap in migration timing with native walleye, and 3) evaluate environmental cues of grass carp migration to BI.
