  • Steven Gratz, Exploring spatial and seasonal stable isotope variation of Channel Catfish and Blue Catfish within a reservoir
  • Jacob Bentley, Food web dynamics and ecological niche of Blue Catfish and other sport fish in Hoover Reservoir using stable isotopes


Dr. Ludsin invited to talk at GLFC

Dr. Stu Ludsin gave an invited talk to the Great Lakes Fishery Commission’s Board of Technical Experts on Tuesday, March 5th. The talk presented findings from a recently completed GLFC project, entitled “Physiochemical and energy landscapes as a driver of Lake Erie walleye population dynamics: past, present & future”, for which former Ludsin Lab member, David Dippold, did his PhD research and several former AEL post-docs (Noel Aloysius, Michael Fraker, Conor Keitzer, and David Glover) conducted research.


Denman Undergraduate Research Forum 2024

Ludsin Lab undergraduate thesis students Paula Joseph and Olivia Houpt, both advised by Stu Ludsin, presented at the Denman Undergraduate Research Forum on March 5, 2024. Both students presented in the category Insects & Other Animal Sciences.

Paula presented on her thesis work, titled, An Otolith Microchemical Approach to Determine Sandusky River Contributions of Recruits to Lake Erie’s Walleye Population Before Removal of the Ballville Dam.

Olivia presented on her thesis work, titled, Understanding the Impact of Bythotrephes longimanus on Yellow Perch Angling Success in Western Lake Erie, for which she was awarded 3rd place in the category.

Ludsin Lab attends Midwest Fish & Wildlife Conference

Ludsin Lab was represented at the 84th Midwest Fish and Wildlife Conference in Sioux Falls, South Dakota, January 28-31, 2024.

Jacob Bentley, MS student studying under Stu Ludsin, and his research technician, Steven Gratz, both presented on Ohio Division of Wildlife funded research on catfish in Ohio reservoirs.

Jacob’s talk was titled, Feeding Ecology of Reservoir-Dwelling Ictalurids in Sympatry and Allopatry.

Steven’s talk was titled, Characterizing Variation in Feeding and Habitat Use of Blue Catfish and Channel Catfish in Reservoirs: A Stable Isotope Approach. Additionally, in his role as Ohio Chapter of the American Fisheries Society president, Steven accepted the award for American Fisheries Society – North Central Division Best Chapter Communications Award.

Dr. Ludsin to Host the 47th Larval Fish Conference, May 2024

Stu Ludsin is hosting the 47th Annual Larval Fish Conference (LFC47) of the Early Life History Section of the American Fisheries Society in May, 2024.

The conference will be held at Sawmill Creek Resort in Huron, Ohio, and will include four days of plenary sessions, a day of optional field trips (choices will include kayaking, touring Stone Lab, visiting a state fish hatchery, and touring a Lake Erie wetland), an early career workshop on preventing burnout, and a bonus Larval Fish ID workshop.

Abstract submission is open, and abstracts are due Friday, March 1.

Lake Erie & Inland Waters Research Review

Dr. Ludsin, in his role as director of the Fish Management in Ohio Partnership with the Ohio Division of Wildlife (DOW), hosted the annual Lake Erie & Inland Waters Research Review December 14-15, 2023. The two-day event had 20 speakers and 13 posters, with presentations on topics from invasive grass carp, to dam removal in Cuyahoga Valley National Park, to the economics of Ohio’s fisheries.

Ludsin Lab members were among the presenters:
