Welcome to the interactive web schedule for the 2019 Midwest Fish & Wildlife Conference! The schedule is subject to change (as of November 7, 2018). Please check back for updates. To return to the main Conference website, go to: www.midwestfw.org.

TIPS FOR NAVIGATING THIS SCHEDULE:
The conference schedule is hosted in SCHED which allows you to search within the schedule, and filter the schedule to show items only occurring on a certain date or within a track/symposia.
  • To view only a certain type of presentation or track, locate the heading "Filter By Type" in the navigation bar. As an example, try clicking on "T01: Fisheries: Great Lakes I".
  • The default view for the schedule is "Simple" which only shows the start time and title of the agenda item. Hover over the button that says "Schedule" to see the different view options. The "Expanded" option will show start and end times, room location, and session description, if there is one.
  • You can build your own schedule by creating a free account with SCHED by selecting "SIGN UP." Watch the "how-to" video to learn more about using Sched. 
  • PLEASE NOTE: Adding agenda items to your schedule through this app does not sign you up for a session. If an agenda item says "pre-registration required" or charges an additional fee, you need to add the item to your registration through the online registration system

AUTHORS: Samuel Schaick, Eastern Illinois University; Cassi Moody-Carpenter, Eastern Illinois University; Aaron Schrey, Georgia Southern University; Katie Miller, Georgia Southern University; David Wahl, Illinois Natural History Survey; Robert Colombo, Eastern Illinois University ABSTRACT: Silver Carp are a non-native fish species that have deleterious effects on the ecosystems they invade. Because of their destructive nature, fisheries managers devote substantial time and effort to limit the spread of these fishes. Better understanding patterns of Silver Carp reproduction and dispersal can help to better manage this invader. To determine spawning locations, we used drift nets and larval push nets in three tributaries the Wabash River to capture larval Hypophthalmichthys (Silver and Bighead Carp) in 2016 and 2017. Further, we used microsatellite loci to determine if genetic differences existed between larval Hypophthalmichthys in our three study tributaries. In total, 1,246 Hypophthalmichthys were collected from three tributaries, with the Little Wabash River and Embarras River producing roughly 83% and 16% of larvae. Having large enough sample sizes at two sites on the Little Wabash River and one site on the Embarras River, we performed genetic analyses and found all three sites had high levels of genetic diversity. Additionally, we found minimal inbreeding or outbreeding present. The middle Little Wabash and lower Embarras River samples were found to be genetically different. We expect this research to improve our understanding of Asian carp reproduction and help fisheries professionals to better mediate their spread.
