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

(SYMPOSIA-11) A Research Path to the Control of Dreissenids Throughout Entire Water Bodies

AUTHORS: Dan Molloy, Molloy & Associates, LLC ABSTRACT: Dreissena mussels pose a significant challenge to infrastructures.  One key element contributing to this challenge is the lack of a practical method for large-scale control of populations once they become established throughout a water body.  As a result, facilities drawing water from such water bodies are subjected to constant reinfestation.Although concerns exist about environmental impacts of molluscicides, it is the prohibitive total project cost of open-water control programs that currently eliminates them as a mitigation option.  Total project cost includes not only the molluscicide and its application throughout the entire water body, but also a myriad of other expenses often required in the overall control program, such as fund raising, administration, regulatory approval, post-treatment mussel mortality monitoring, report writing, etc.The research project reported herein offers a potential solution to this seemingly intractable problem of prohibitively high control program expense.  The key to the low cost of this proposed control approach is that it does not require treatment of the entire water body.  In contrast to traditional control programs: 1) only a minuscule portion of the infested water body’s volume would be treated (“seeded”) with the control agent; and 2) the control agent would subsequently amplify itself and self-spread throughout the water body.  There is only one type of control agent capable of doing that – a live one, a biological control agent.This presentation describes the research conducted in the first year of a multi-year project to find such a control agent.  The project is based in Eurasia and specifically designed to find a hypervirulent (i.e., extremely lethal), highly-specific dreissenid parasite that one day (following years of comprehensive environmental safety studies) would be introduced into North American water bodies where it will leave a trail of dead dreissenids in the path of its spread.
