AFS Symposium on Walleye, Sauger and Yellow Perch

Posted on Dec 12, 2019

A symposium on the biology management and culture of walleye, sauger and yellow perch will be held during the American Fisheries Society Annual Meeting in Columbus, Ohio (August 30 - September 3, 2020).

Walleye, one of the most sought-after species of freshwater sport fishes in North America, and its “sister” species, the Sauger, have demonstrated appreciable declines in their numbers from their original populations since the beginning of the 20th century. Similarly, Yellow Perch, once the most commonly caught sport fish and an important commercial species in North America, have also shown declines. Yet, some western states and provinces are trying to extirpate Walleye and Yellow Perch where they have been introduced outside of their native range. The purpose of this one-day symposium is to present up-to-date information on the biology and management of Walleye, Sauger, and Yellow Perch, since the 2011 publication of the AFS book, Biology, Management, and Culture of Walleye and Sauger, the companion column in Fisheries that year (36[12]), Future Research Needs of Walleye and Sauger, and pertinent review papers in Biology of Perch (CRC Press, 2015). Presentations will include topics on systematics, genetics, physiology, ecology, population dynamics, culture, recent case histories, and management practices, which will be of interest to managers, researchers, and students who deal with these important species, particularly in light of habitat alterations, population shifts, and other biotic and abiotic factors related to a changing climate. 
If you are interested in presenting a talk on Walleye, Sauger, or Yellow Perch at the American Fisheries Society’s 150th annual meeting, please contact John Clay Bruner (jbruner [at] to be included in the symposium.
Proposals for Symposia must be submitted by January 21, 2020. Accepted Symposia proposals will be posted on the conference website on February 14, 2020. If accepted, organizers must submit a complete list of confirmed presentations and titles by March 13, 2020. Abstracts for Symposium oral presentations must be submitted by March 20, 2020
