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

ABSTRACT: Age information is a management tool used by fisheries biologists to characterize populations. The Blue Catfish (Ictaluris furcatus) is a riverine species that grow to trophy lengths and have been introduced into Kansas Reservoirs. Blue Catfish were introduced into Wilson Reservoir in 2006 and Lovewell Reservoir in 2010 with a common management objective, establishing a trophy fishery. Standard sampling protocol (SSP) has misrepresented the Blue Catfish population status in both reservoirs; a targeted sampling effort was conducted in the summer of 2016 in Lovewell Reservoir using low-pulse electrofishing and in 2017 using float-lines to gain insight on the population structure. A total 170 fish were collected from Wilson Reservoir with a TL ranging 210-860 mm. We sampled Lovewell Reservoir and collected 146 individuals ranging from 220-860 mm. Pectoral spines were collected from each individual and used for aging. Annual stockings were scheduled for Lovewell reservoir from 2010-2014 approximately at 1 fish/acre excluding the year 2013 stocking at 0.33 fish/acre. Age 6 fish comprised 52% of the sample, 2% at age 5, 13% age 4, 3% age 3, 23% age 2, and 4% age 1. Wilson Blue Catfish stocking rates were conducted at 2 fish/acre in 2006 and 2008; stocking rates were 1 fish/acre in 2007, 2010, 2011, 2012, 2013, 2014, and 2016. Age 11 fish made up 13% of the sample, age 10 at 49%, 36% were age 9, and 7% age 1. Age classes 2, 3, 4, 5, 6, and 7 were not represented in the sample. Detection of these missing year classes may have been caused by low lake levels during this time period.
